Maven 1

• Type: Bug
• Status: Closed
• Priority: Critical
• Resolution: Fixed
• Affects Version/s: 1.1-beta-2
• Fix Version/s: 1.1-beta-3
• Component/s: core
• Labels:

  None
• 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
  

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

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
build:start:

java:prepare-filesystem:
[mkdir] Created dir: /home/henning/scratch/test/maventest/target/classes

java:compile:

Both tasks, java:compile and jar:jar work fine and as expected using maven-1.0.2

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.
