Brett Porter updated MAVEN-1690:
--------------------------------
Fix Version: 1.1-beta-3
> maven 1.1 beta 2 confuses class loaders while compiling plugin-genererated
> code
> -------------------------------------------------------------------------------
>
> Key: MAVEN-1690
> URL: http://jira.codehaus.org/browse/MAVEN-1690
> Project: Maven
> Type: Bug
> Components: core
> Versions: 1.1-beta-2
> Environment: java version "1.4.2_09"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-b05)
> Java HotSpot(TM) Client VM (build 1.4.2_09-b05, mixed mode)
> Fedora Core 3 Linux on x86
> Reporter: Henning Schmiedehausen
> Priority: Critical
> Fix For: 1.1-beta-3
> Attachments: maventest.tar.gz
>
>
> This is a bit complicated to describe, so I've prepared an example to provoke
> this bug.
> - Unpack the attached maventest.tar.gz
> - install the Torque Plugin into your maven by running
> maven -DartifactId=maven-torque-plugin -DgroupId=torque -Dversion=3.1.1
> plugin:download
> % cd maventest ; maven -q java:compile
> build:start:
> java:prepare-filesystem:
> [mkdir] Created dir: /home/henning/scratch/test/maventest/target/classes
> java:compile:
> build-om:
> torque:init:
> BUILD FAILED
> File...... /home/henning/.maven/cache/maven-torque-plugin-3.1.1/plugin.jelly
> Element... taskdef
> Line...... 87
> Column.... -1
> taskdef A class needed by class
> org.apache.torque.task.TorqueJDBCTransformTask cannot be found:
> org/apache/xerces/dom/CoreDocumentImpl
> The missing class is inside the xerces jar, which is put on the classpath by
> the torque plugin (see
> http://svn.apache.org/viewcvs.cgi/db/torque/maven-plugin/trunk/plugin.jelly?rev=239621&view=markup,
> the torque:init task defines the classpath exactly as described on
> http://maven.apache.org/faq.html#classloader-property)
> Funnily enough, the "jar:jar" task, which runs java:compile as a prerequisite
> works:
> % cd maventest ; rm -rf target ; maven -q jar:jar

> This is a test case for a real world example, trying to compile and build the
> site for the turbine 2.3.2-rc1 release. The classpath error
> occurs when the site build process tries to run jdepend to build the metrics.
> So the problem doesn't seem to be part of the plugins or
> tasks but of the core.
