Feel free to continue that wiki page if you find a solution. The final goal is to build completely that helloWorld project in a mode that allows it to be used on a buildd.

Testing Maven with the JPP patchset

This document describes how you can play with Maven-Jpp so far. We are trying to do a minimal proof-of-concept for the maven-jpp design alternative presented in MavenSupportSpec.

Add "deb http://ppa.launchpad.net/ubuntu-java/ubuntu intrepid main" to your /etc/apt/sources.list then install maven2: 

$ sudo apt-get update
$ sudo apt-get install default-jdk maven2

Create a helloWorld maven2 project: 

$ mvn archetype:create -DgroupId=com.mycompany.test -DartifactId=helloWorld

Don't cheat, remove the resulting .m2 directory: 

$ rm -rf .m2

The JPP-ized maven2 will lack a few files (that should be provided by missing separate packages or as additions to existing packages). We'll copy them from a tar file for the time being: 

$ wget http://people.ubuntu.com/~koon/maven-jpp-addons.tar.gz
$ tar zxf maven-jpp-addons.tar.gz
$ cd maven-jpp-addons
$ sudo cp maven-jpp-addons/etc/maven2/maven2-versionless-depmap.xml /etc/maven2
$ sudo cp -r maven-jpp-addons/usr/share/maven2/plugins /usr/share/maven2
$ sudo cp -r maven-jpp-addons/usr/share/maven2/default_poms /usr/share/maven2
$ sudo mkdir /usr/share/java/maven2
$ sudo ln -s /usr/share/maven2/default_poms /usr/share/java/maven2/default_poms
$ sudo ln -s /usr/share/maven2/plugins /usr/share/java/maven2/plugins

Then you can try to compile the project in JPP-mode ! 

$ sudo apt-get install libplexus-compiler-api-java libplexus-compiler-javac-java libplexus-compiler-manager-java junit
$ cd helloWorld/
$ mvn -Dmaven2.offline.mode -Dmaven2.ignore.versions -Dmaven2.usejppjars compile

(the CHECKSUM warnings are normal)

You should get the error I get: 

[INFO] Internal error in the plugin manager executing goal 'org.apache.maven.plugins:maven-compiler-plugin:2.1-SNAPSHOT:compile': Unable to find the mojo 'org.apache.maven.plugins:maven-compiler-plugin:2.1-SNAPSHOT:compile' in the plugin 'org.apache.maven.plugins:maven-compiler-plugin' 
Component descriptor cannot be found in the component repository: org.codehaus.plexus.compiler.manager.CompilerManager.

$ mvn -e -Dmaven2.offline.mode -Dmaven2.ignore.versions -Dmaven2.usejppjars compile
