directory
---------------------------------------------------------------------------------------
Key: MSHADE-75
URL: http://jira.codehaus.org/browse/MSHADE-75
Project: Maven 2.x Shade Plugin
Issue Type: Bug
Affects Versions: 1.3.1
Environment: Ubuntu 9.04 - Jaunty Jackalope -, Eclispse (Galileo),
java 1.6.0_16
Reporter: Yoann Yonnet
Attachments: patch-maven-shade-plugin.txt
Hello,
I make a maven aggregator project with two modules.
The first module is a dependency of the second.
The first module is build with the install goal.
The second with the shade plugin during the package phase.
The first module build runs successfully and install resulting jar file in the
maven local repository.
The second module build fails with this error :
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR

It's due to the shade plugin whose tries to reference first module classes from
target/classes repository instead of the jar file previously build.
Therefore, it seems that the shade plugin doesn't work with a maven
multimodules project.
I manage to build my maven aggregator project by applying the attached patch
(patch-maven-shade-plugin.txt) on the class ShadeMojo.java
