Starting Ant with the lib option to specify a path to search for jars and classes isn't working in 1.6.1. The problem is in the /usr/bin/ant script, because ant is started by running Ant's traditional entry point. [snip from ant manual: http://ant.apache.org/manual/running.html#viajava] Ant can be started with two entry points: - java -Dant.home=c:\ant org.apache.tools.ant.Main [options] [target] - java -Dant.home=c:\ant org.apache.tools.ant.launch.Launcher [options] [target] The first method runs Ant's traditional entry point. The second method uses the Ant Launcher introduced in Ant 1.6. The former method does not support the -lib option and all required classes are loaded from the CLASSPATH. You must ensure that all required jars are available. At a minimum the CLASSPATH should include: * ant.jar and ant-launcher.jar * jars/classes for your XML parser * the JDK's required jar/zip files The latter method supports the -lib option and will load jars from the specified ANT_HOME. You should start the latter with the most minimal classpath possible, generally just the ant-launcher.jar. [snip end] Library Directories in Ant 1.6: http://ant.apache.org/manual/running.html#libs so i changed some lines of the gentoo-ant script to get it (for me) working: - removed the hardcoded classpath - starting ant using the new entrypoint #! /bin/bash # Copyright (c) 2001-2003 The Apache Software Foundation.

Reproducible: Always Steps to Reproduce: 1. ant -lib /home/ant/extras Actual Results: The Ant help text appears. Expected Results: Seraching for extra libaries in the specified directory and starting the build process. without jikes (USE="-jikes")
Thanks, fixed in portage ;)
