Multi-module maven build : different result from parent and from module
- by Albaku
I am migrating an application from ant build to maven 3 build.
This app is composed by :
A parent project specifying all the modules to build
A project generating classes with jaxb and building a jar with them
A project building an ejb project
3 projects building war modules
1 project building an ear
Here is an extract from my parent pom :
<groupId>com.test</groupId>
<artifactId>P</artifactId>
<packaging>pom</packaging>
<version>04.01.00</version>
<modules>
<module>../PValidationJaxb</module> <-- jar
<module>../PValidation</module> <-- ejb
<module>../PImport</module> <-- war
<module>../PTerminal</module> <-- war
<module>../PWebService</module> <-- war
<module>../PEAR</module> <-- ear
</modules>
I have several problems which I think have the same origin, probably a dependency management issue that I cannot figure out :
The generated modules are different depending on if I build from the parent pom or a single module. Typically if I build PImport only, the generated war is similar to what I had with my ant build and if I build from the parent pom, my war took 20MB, a lot of dependencies from other modules had been added. Both wars are running well.
My project PWebService has unit tests to be executed during the build. It is using mock-ejb which has cglib as dependency. Having a problem of ClassNotFound with this one, I had to exclude it and add a dependency to cglib-nodep (see last pom extract). If I then build only this module, it is working well. But if I build from the parent project, it fails because other dependencies in other modules also had an implicit dependency on cglib. I had to exclude it in every modules pom and add the dependency to cglib-nodep everywhere to make it run.
Do I miss something important in my configuration ?
The PValidation pom extract :
It is creating a jar containing an ejb with interfaces generated by xdoclet, as well as a client jar.
