UnsupportedOperationException in multi module project
-----------------------------------------------------
Key: MJAVADOC-156
URL: http://jira.codehaus.org/browse/MJAVADOC-156
Project: Maven 2.x Javadoc Plugin
Issue Type: Bug
Environment: Maven version: 2.0.7 Java version: 1.4.2 OS name:
"windows xp" version: "5.1" arch: "x86"
Reporter: Michele Lorenzini
Dealing with MJAVADOC-135, I switched on maven-javadoc-plugin version
2.4-SNAPSHOT
and I found the following problem:
when creating the javadoc report for site in a multimodule project (using a
flat directory layout, so all three projects on the same
level), UnsupportedOperationException is thrown.
Say I have projA and projB each of them delcare maven-javadoc-plugin
2.4-SNAPSHOT as report dependency.
If I run mvn site on each project indipendently, the site (with javadoc report)
works fine.
If I create a pom project which declares projA and projB as modules, running
mvn site on there fails with the following exception:
java.lang.UnsupportedOperationException

If i set the plugin dependency to maven-javadoc-plugin 2.3 the same goal runs
fine.
This will become an issue for me as I am waiting for 2.4 to solve MJAVADOC-135
and I have a multimodule structure as the one described above.
I will post a sample project in a while.
