Skipping the TAR packaging step
Hello,
I'm working on a large project that takes time to compile. I would like to
instruct Maven to only build the jar file, but after the build I have a tar,
tar.bz2, and a zip file. I am brand new to Maven, but have converted a
project to use Maven for the compilation of all component modules. In
general, I want to indicate to Maven to only create me a jar with all
dependencies rolled into that jar, and nothing else. This can be for a
particular profile, one for specific for development. The wait is too long
when I make a small change.
So I have a parent pom that is the kind that aggregates all sub-modules. In
any given module that I want to generate an executable jar for, I have a
section that looks like this:
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>${maven.assembly.plugin.version}</version>
<configuration>
<descriptors>
<descriptor>../config/maven/single-jar-assembly.xml</descriptor>
</descriptors>
<archive>
<manifest>
<mainClass>com.company.MainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
The assembly starts like this:
<assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2
http://maven.apache.org/xsd/assembly-1.1.2.xsd">
<id>all</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
I don't have any concept of a profile right now, but I want right now to
simply suppress the creation of all the extra build artifacts. Is there a
way to do that?
Sorry if it's been asked before, but I have either not found it, or when I
did find it, I didn't understand what needed to be done. I barely eked out
the assembly.xml that I did create.
Thanks for any help you can provide,
Scott

Right now the entire project is being refactored, so I don't have much of a
choice right now.

You will probably get a big improvement by breaking your project into
smaller functional modules (Think SOA) that are more stable and do not
have to be compiled for every change.
They just become dependencies in the higher level modules and are
brought in automatically by maven as required.

Thanks, Guillaume. I'll read through the links you've provided carefully to
see if I can make this happen.

Re: Skipping the TAR packaging step

Hi,
from what you provide us, I think that you are using the predefined
descriptor 'project' of maven assembly plugin which produces by default
a zip, a tar.gz and a tar.bz2 file
(http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html).
Now, if you want a single big fat jar containing all the classes, just
switch to the descriptor 'jar-with-dependencies' which will unpack all
the jar you depend on and recreate a big jar file containing all the
unpacked classes, plus, the ones of your current project.
Now, if you want to keep those three files (zip, tar.gz and tar.bz2) but
you want to have 2 different kind of builds:
* one that produces the jar file of the current project
* one that produces everything as now
You have two options:
1) you create 2 profiles, one that contains the maven assembly plugin
and another one without it.
2) you bind the assembly plugin to a phase which is after the phase
"package" (for example, "verify"), and in the first case you only call
'mvn package' and the second one you call 'mvn verify'
If what you want is to have a build with:
* one that produces the big fat jar file
* one that produces everything as now
Your only choice is to use profile and configure the maven assembly
plugin differently in each profile.
If you look for information on profiles, go here:
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
If you look for information on lifecylce, phases, etc..., go here:
http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
Be careful with profiles because, as mentioned on the maven site, there
are several pitfalls to profiles.
Cheers,
Guillaume

Wayne,
Thanks for the reply.
I am the resident expert with Maven, so I am the only help I have. If we
had someone like you are describing, I would very happy indeed. So far
though, things are looking good, but it's like walking through the dark with
a flashlight.
As for the other formats, I'm not looking to get rid of them forever, only
in the iterative development cycle where I compile, deploy and test upwards
to 20 times a day. The jar is all I need in this situation.
The old build was done exclusively with Ant.
My guess about why I'm generating so many different deployment artifacts is
that it is due to the assembly plugin in my project pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>${maven.assembly.plugin.version}</version>
<executions>
<execution>
<id>create-project-bundle</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptorRefs>
<descriptorRef>project</descriptorRef>
</descriptorRefs>
</configuration>
</execution>
</executions>
</plugin>
Is there a way to configure this to only generate the jar? If I am to use
the shade plugin, how do I configure it to indicate the suppression I'm
looking for? I read the usage page for both plugins but haven't found what
I'm looking for (though I admit I could easily have missed it).
Thanks,
Scott

Realistically I think you should be looking for LOCAL help (from
someone else in your project team, who knows Maven better than you do
-- who set these projects up originally?) rather than asking here on
Maven Users...

This should be pretty simple since Jars are the default.

You "converted" from what - Ant?

You do realize that very few classloaders will support the "jar in a
jar" approach, right? You should probably look into the shade plugin
if you seriously want to pursue this.

Nothing that you've sent shows anything about tar, bz2 or zip. Is that
coming from another parent or a profile? Or later in the assembly.xml
file? Or elsewhere in the same pom file, and you just didn't send it?

Try "mvn help:effective-pom" in your project dir to see the actual pom
as interpreted by Maven.
