Description J.D. Bertron 2009-12-02 10:21:13 UTC

The task: <taskdef resource="net/sf/antcontrib/antlib.xml"/> fails to find the ant-contrib tasks, despite the ant-contrib.jar appearing in both the ant.lib and java.class.path when running ant -diagnostics (below).
However, when setting the environment variable CLASSPATH to equal the value of java.class.path, the taskdef succeeds.
NOTE: The new value reflected by java.class.path is now double the original size and references ant-contrib.jar twice.

Comment 1 J.D. Bertron 2009-12-02 10:44:07 UTC

On further investigation, only exporting CLASSPATH=/usr/share/ant/lib/ant-contrib.jar was enough to resolve the issue. This still doesn't exclude a possible conflict between libraries but it definitely helps narrow down a test case.
