Javac Run By Ant Script is Unable to Find External Jars
I had a working ant script until I made a number of source changes to my
Java project via Eclipse and egit. I obviously somehow inadvertently
changed something, somewhere, that is causing javac to not find
libraries (perhaps pushed something via git that is not part of the
source). There are some Maven libraries and external jars in the build
path (as displayed by Eclipse) but it seems they are not being found
with the ant script. This is the ant output:

The zipfileset tags are seemingly being ignored and I don't know how it
knows to include the external jar (org.json.simple). Since this was
working I am guessing that something changed external to the ant script
but I don't know what or where to look. I don't know how the build path
that I see in Eclipse (which is correct and works) fits into all this.
I'm hoping someone can point me in the right direction. TIA.

Hi Jan,
That was it. Thanks.
I had that at one time but I thought those were no longer necessary
since I added all the pom and maven stuff. Now I'm not sure what is
necessary but since it is working I'll leave it alone.

AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
I think Eclipse is creating a shaded jar, means a jar which contains all external jars.
So you would have to download these jars and include their content in your final archive.
You could use <zipfileset> for getting their content
<jar destfile="myjar.jar">
<fileset dir="classes"/>
<zipfileset src="lib/dependency1.jar"/>

Betreff: AW: Javac Run By Ant Script is Unable to Find External Jars
I've figured out what the problem is but I don't know what to do to fix it. When I export the jar from Eclipse, it has this set of directories:
KCBSEvents
META-INF
mozilla
org
src
That is the one that works. When I build the jar using ant (below), these are the directories present:
KCBSEvents
META-INF
It is obvious now what the problem is. I just need to know how to get ant to include those same directories.

If you have created your JAR the first step is done.
Starting the JAR could be done in several ways. Common is that you have to have all external classes on the runtime classpath:
1. Hard coded start script.
Write a bash/bat-Script with the java command with all cp settings, e.g. (bat)
@echo off
java -cp /build/myjar.jar;lib/one.jar;lib/two.jar;lib/three.jar org.acme.Main %*
2. Wrapper script which collects all JARs in a dynamic way (see ant.bat|ant.sh)
3. Use Ant + <java><classpath> for starting
4. Create a runnable JAR which references the external JARs (manifest: main-class + classpath)
5. Create a shaded jar (uber jar, fat jar): include all classes from external jars into your jar
6. Use a launcher which uses a dependency manager for getting the classpath
You don't have to replicate path definitions in your buildfile, you could (and should) use references:
<javac><classpath id="runtime.cp"><fileset dir="lib" includes="**/*.jar"/>…
<java><classpath refid="runtime.cp"/>
You mave have a look at http://ant.apache.org/manual/tutorial-HelloWorldWithAnt.html

AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
I've figured out what the problem is but I don't know what to do to fix
it. When I export the jar from Eclipse, it has this set of directories:
KCBSEvents
META-INF
mozilla
org
src
That is the one that works. When I build the jar using ant (below),
these are the directories present:
KCBSEvents
META-INF
It is obvious now what the problem is. I just need to know how to get
ant to include those same directories.

Re: AW: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
Hi Jan,
I need to take a timeout. In my machinations I've created a new problem
that seems unrelated to ant. I'm trying to resolve that via the Eclipse
forum. I don't know if this new problem is masking the original one or
if it is related. I'll have to get back to you when I know which.

AW: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
A little sample:
* src\java\org\apache\ant\Application.java
Sample application which uses Log4J2 as external dependency
* src\resources\log4j2.xml
Configuration file for Log4J2
* build.xml
Ant buildscript
Run the script with "ant".
Then start the application with "java -jar lib\Application.jar".
The app will prompt all given arguments via Log4J2-Logger.
Have a look at the "build" target and the resulting manifest inside the jar.

AW: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
Could you post the content of the manifest file and your directory structure?
I suppose that the paths are not correct …

Betreff: Re: AW: Javac Run By Ant Script is Unable to Find External Jars
My apologies again but I have not made any progress on this problem. Is there perhaps a better forum I should be using at this point? I did make one discovery. It appears that although the application works in Eclipse when I try to export it to a runnable jar using the Eclipse wizard, the resulting jar fails as well. It seems to me that the problem is not ant specific but something in the app build per se.

Starting the JAR could be done in several ways. Common is that you have to have all external classes on the runtime classpath:
1. Hard coded start script.
Write a bash/bat-Script with the java command with all cp settings, e.g. (bat)
@echo off
java -cp /build/myjar.jar;lib/one.jar;lib/two.jar;lib/three.jar org.acme.Main %*
2. Wrapper script which collects all JARs in a dynamic way (see ant.bat|ant.sh)
3. Use Ant + <java><classpath> for starting
4. Create a runnable JAR which references the external JARs (manifest: main-class + classpath)
5. Create a shaded jar (uber jar, fat jar): include all classes from external jars into your jar
6. Use a launcher which uses a dependency manager for getting the classpath
You don't have to replicate path definitions in your buildfile, you could (and should) use references:
<javac><classpath id="runtime.cp"><fileset dir="lib" includes="**/*.jar"/>…
<java><classpath refid="runtime.cp"/>

Re: AW: Javac Run By Ant Script is Unable to Find External Jars

I found an article on adding Maven dependencies to my ant script. While
I'm getting a successful build but the same exception when I run the
jar, I hope this is getting me closer. At least the pom.xml is in the

Re: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
Hi Jan,
Thanks. I'm using option 4. At least that is what my build file is
supposed to be doing. The problem is while the build is successful there
is something wrong with the jar produced. I suspect the Maven
dependencies are not linked in correctly in the compiled jar because the
pom.xml is not being included in the build.

AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
If you have created your JAR the first step is done.
Starting the JAR could be done in several ways. Common is that you have to have all external classes on the runtime classpath:
1. Hard coded start script.
Write a bash/bat-Script with the java command with all cp settings, e.g. (bat)
@echo off
java -cp /build/myjar.jar;lib/one.jar;lib/two.jar;lib/three.jar org.acme.Main %*
2. Wrapper script which collects all JARs in a dynamic way (see ant.bat|ant.sh)
3. Use Ant + <java><classpath> for starting
4. Create a runnable JAR which references the external JARs (manifest: main-class + classpath)
5. Create a shaded jar (uber jar, fat jar): include all classes from external jars into your jar
6. Use a launcher which uses a dependency manager for getting the classpath
You don't have to replicate path definitions in your buildfile, you could (and should) use references:
<javac><classpath id="runtime.cp"><fileset dir="lib" includes="**/*.jar"/>…
<java><classpath refid="runtime.cp"/>

Hi Jaikiran,
Thanks for the reply. Here is my command:
/bin/ant -v -Dmember.number=$number -Dmember.name=\"$name\" -f makejar.xml
I assume it is using ant's java task based on the build file (makejar.xml). I'm a bit confused. Doesn't all the necessary classpath info come from the build xml? Since the Maven pom.xml is never referenced anywhere in the build file and the Maven dependency causes that exception, it seems to me that is where the problem lies. Doesn't the pom.xml need to be referenced somewhere?
In any case, how do I set up a classpath for the ant command (-lib) since I have multiple paths? Do I have to copy all my jars into a single directory? Why is duplication of these paths even necessary? This seems like it is getting far afield since I did not have to do all that before I messed up the build file classpath.

Does this come back to my question about needing the zipfileset

I would start by locating the folder where your third-party dependencies
are and create a <path> element containing them like this:
<path id="compile-classpath">
<fileset dir="/the/path/to/your/third/party/jars"/>
</path>
Once you have a path defined you can pass the classpath to the <javac> task
using a refid like this:
<javac srcdir="src" destdir="bin" includeantruntime="false"
classpathref="compile-classpath"/>
Try that and see how it goes.

Re: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
Hi Jaikiran,
Thanks for the reply. Here is my command:
/bin/ant -v -Dmember.number=$number -Dmember.name=\"$name\" -f
makejar.xml
I assume it is using ant's java task based on the build file
(makejar.xml). I'm a bit confused. Doesn't all the necessary classpath
info come from the build xml? Since the Maven pom.xml is never
referenced anywhere in the build file and the Maven dependency causes
that exception, it seems to me that is where the problem lies. Doesn't
the pom.xml need to be referenced somewhere?
In any case, how do I set up a classpath for the ant command (-lib)
since I have multiple paths? Do I have to copy all my jars into a single
directory? Why is duplication of these paths even necessary? This seems
like it is getting far afield since I did not have to do all that before
I messed up the build file classpath.

Re: Javac Run By Ant Script is Unable to Find External Jars
Posted by Jaikiran Pai <ja...@apache.org>.
Hi Dennis,
I think you are almost there to get this working. How are you running
this Java application? Are you using Ant's java task? What does it look
like? Just like you did with javac, the java task will need to know what
classpath to use while running the application. As long as you setup
your classpath to contain all these necessary jar files, you should no
longer see those exceptions.

Hi Matt and Jan,
Thanks to both of you as I am closer but I think I am still missing a
piece. I am now getting a successful build but the resulting jar is not
finding the classes in the external jars. When I run the jar I get this
exception:

Does this come back to my question about needing the zipfileset elements
for the Maven jars? I don't know how the pom.xml for Maven gets pulled
into this either.

Hi Matt,
Thanks for that information. Since this used to work I guess somewhere
along the line I must have deleted that classpath info. I will give this
a try. In the mean time does this mean I don't need the zipfileset
elements if I include those jars in the path element? Or do I still need
both because they are Maven dependencies?

AW: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
Yes.
Eclipse uses .project and .classpath.
Ant uses build.xml (and an often used file build.properties).
In contrast to Maven or Gradle Ant doesn't come with a built in dependency manager.
So just declaring "I need JUnit 4.12" doesn't work.
- place the jars by yourself in a directory (e.g. "/libs") and reference that (libs are stored in vcs)
- have a "download script" that places the jars inside that folder (libs are not stored in vcs, only the dependency declaration in the download script)
- use the maven tasks for downloading the files (see Ant's fetch.xml)
- use Ivy as dependency manager and use it to define the path's (see Ant's check.xml)

Re: AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
Hi Jan,
Thanks. Things are starting to come together in my head. If I
understand, ant doesn't need the Eclipse .classpath at all and only the
classpath suggested by Matt is used by ant, right?

AW: Javac Run By Ant Script is Unable to Find External Jars
Posted by "Jan Matèrne (jhm)" <ap...@materne.de>.
Matt is correct: you are mixing Eclipse and Ant definitions.
So here some points by me:
* There is no default behaviour of <javac>. You have to specify the paths the compiler should use by yourself.
* <javac ... classpath=".classpath"/> means, that the file or directory ".classpath" should be used for classpath. But the .classpath-file is not a jar file, it is a xml file.
* I try to "translate" the .classpath:
Eclipse: <classpathentry including="**/*.java" kind="src" output="target/classes" path="src">
Ant: <javac src="src" dest="target/classes" includes=**/*.java"/>
Eclipse: <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">
Ant: not used (include current Java runtime)
Eclipse: <classpathentry kind="lib" path="/lib/java-ext/json-simple-1.1.1/json-simple-1.1.1.jar"/>
Ant: <javac><classpath><path entry="/lib/java-ext/json-simple-1.1.1/json-simple-1.1.1.jar"/></classpath></javac>
ore more generic
<javac><classpath><fileset dir="lib" includes="**.*.jar"/></classpath></javac>
Eclipse: <classpathentry kind="output" path="target/classes"/>
Ant: not used (I think this controlls the "export behaviour" for inter-project dependencies)
So combined (and tuned):
<property name="build.classes" value="target/classes"/>
<mkdir dir="${build.classes}"/>
<javac src="src" dest="${build.classes}"> <!-- includes not required -->
<classpath>
<fileset dir="lib" includes="**.*.jar"/>
</classpath>
</javac>

Re: Javac Run By Ant Script is Unable to Find External Jars
Posted by Matt Bertolini <vi...@gmail.com>.
Hi Dennis,
I think you might be mixing up Eclipse concepts and Ant concepts and that
might be causing some extra confusion. Based on your original email, the
compiler is having issues finding your third-party dependencies. I believe
Jaikiran is correct in saying that the <javac> task needs to be given some
sort of classpath. The .classpath file is an Eclipse concept and unless
there is some sort of Eclipse/Ant plugin I am not aware of, the .classpath
file will have no effect on Ant’s, <javac> task. Also, I don’t believe the
<javac> task has a default value for the classpath attribute. If no
classpath or classpathref is specified then the compiler is not passed any
classpath information.
I would start by locating the folder where your third-party dependencies
are and create a <path> element containing them like this:
<path id="compile-classpath">
<fileset dir="/the/path/to/your/third/party/jars"/>
</path>
Once you have a path defined you can pass the classpath to the <javac> task
using a refid like this:
<javac srcdir="src" destdir="bin" includeantruntime="false"
classpathref="compile-classpath"/>
Try that and see how it goes.

Re: Javac Run By Ant Script is Unable to Find External Jars
Posted by Dennis Putnam <da...@bellsouth.net>.
I apologize for being a pest but this is a problem I cannot resolve on
my own. The more I read the more confusing it gets. It seems like there
are thousands of ways to accomplish what I want but none make any more
sense than what I have. Is there no one that can help me debug this
problem or at least point me in the right direction?

Hi Jaikiran,
Thanks for the reply. I thought the classpath parameter defaulted to
"basedir"/.classpath. In any case I made the following change:
<javac srcdir="src" destdir="bin" includeantruntime="false" classpath=".classpath" />
Unfortunately that didn't help. The ant output is exactly the same. FWIW
here is .classpath:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry including="**/*.java" kind="src"
output="target/classes" path="src">
<attributes>
<attribute name="optional" value="true"/>
<attribute name="maven.pomderived"
value="true"/>
</attributes>
</classpathentry>
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">
<attributes>
<attribute name="maven.pomderived"
value="true"/>
</attributes>
</classpathentry>
<classpathentry kind="lib"
path="/lib/java-ext/json-simple-1.1.1/json-simple-1.1.1.jar"/>
<classpathentry kind="con"
path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
<attributes>
<attribute name="maven.pomderived"
value="true"/>
</attributes>
</classpathentry>
<classpathentry kind="output" path="target/classes"/>
The "lib" path is correct. I am guessing that the next tag essentially
points the pom.xml so here it is in case it matters:

Presumably the maven libraries are found from the zipfilesets in the ant
script.

I don't see any classpath being passed to the javac task in your build
script. You should be passing a classpath containing your jars that are
required to compile the source. There's more than one way to do that.
The javac task manual has more details about it
