custom ant task can't find classpath
i'm having a problem with one my taskdefs.
the custom task that i've created is basically calling a .class located in
a .jar and passing it some parameters.
the part of the build.xml file calling my custom task basically looks like this.
<target name="modifyIt">
<taskdef name="mytask" classname="com.mycom.MyCustomTask">
<classpath>
<pathelement location="/dev/anttasks/mytasks.jar"/>
</classpath>
</taskdef>
<mytask param1="abc" helperJar="/java/helper/123/helper.jar"/>
</target>
</project>
my custom task is calling the Help.class in the helper.jar.
the command line that is constructed by my custom task ("mytask") and that
is executed is:
(i'm using windows2000, so all the paths are converted appropriately)
c:\java\j2se\sun\131_02\bin\java.exe -classpath
c:\java\helper\123\helper.jar Help abc
if i type in this command at the dos prompt, it works. however, when my
ant script runs, ant complains that it could not find Help and that i
should check to see if i have it in my classpath. i'm getting the same
error when i try to run my script from within netbeans also...
any advice is greatly appreciated.

looks like:
ExecuteJava execJava = new ExecuteJava();
execJava.setClasspath( helperJarFile );
did the trick. thank you.
i missed the "setClasspath()" method. perhaps it's just me, but that
method seems better suited for the CommandlineJava class...
anyway, the ant task works (at the command line), but i'm now getting the
following when i try to run the task from within netbeans:
org.netbeans.core.execution.ExitSecurityException

i think that this is more of a netbeans issue than ant, so no replies
necessary, but if you also use ant with netbeans and have experienced this,
i'd appreciate any hints.
does it mean that the java .class is trying to call something like
System.exit(0) and netbeans won't permit it b/c if it does, netbeans also
will exit? for those familiar with ant, does this mean that i have to
"fork the vm" when i execute my java .class?
thank you.

i tried:
Commandline cmdline = new Commandline();
Path p = cmdline.createClasspath( getProject() );
p.setLocation( helperJarFile );
this, but when i print out the parameters that are being used for the
command line, the classpath appears to be null. as a result, i'm setting
the classpath by doing the following:
cmdline.createArgument().setValue("-classpath");
cmdline.createArgument().setValue(absolutePathToJarFile);
everything else is the same. i will try your suggestion for setting the
classpath.
thank you.

Hi,
It's kinda hard to figure out what's going wrong without seeing your code.
Using ExecuteJava is pretty straight-forward, though - you should be doing
something like this in your task:
public void execute()
{
Path classpath = new Path( getProject() );
classpath.setLocation( helperJarFile );
Commandline cmdline = new Commandline();
cmdline.setExecutable( "Help" );
cmdline.createArgument().setValue( param1 );
ExecuteJava exe = new ExecuteJava();
exe.setCommandline( cmdline );
exe.setClasspath( classpath );
exe.execute( getProject() );
}

Can't put optional tasks jar out of ant/lib
Posted by Nicola Ken Barozzi <ni...@apache.org>.
I'm trying to use the JDepend optional task without having to put the
jdepend.jar in the ant/lib dir.
So I have (yesterday's CVS version of jar):
./tools/ant/lib/ant.jar
./tools/ant/lib/optional.jar
./tools/tmp/tasks.properties (containing the task definition)
./tools/other/lib/jdepend.jar
I write:
<!-- define the tasks found in cents -->
<taskdef file="./tools/tmp/tasks.properties">
<classpath>
<fileset dir="./tools">
<include name="**/*.jar"/>
</fileset>
</classpath>
</taskdef>
But in verbose mode it says:
[taskdef] Loading definitions from file
C:\jbprojects\jakarta-poi\tools\tmp\ta
sks.properties
BUILD FAILED
C:\jbprojects\jakarta-poi\build.xml:68: taskdef class

If I put jdepend.jar in ant/lib it works but I don't want to do it.
Also changeing the script is not an option because some use build.xml
directly with ant called via java.
Any clues?
Thanks in advance :-)

How does your task call the Help class? Reflection? ExecuteJava? Execute?
Runtime.exec()?
