Ant version 1.6 dies on some computers with the following: Invalid implementation version between Ant core and Ant optional tasks. core : 1.5.1 optional: 1.6.0 However the optional tasks are from the ebuild ant-optional-1.6 and the ant ebuild used is 1.6 Both builds have been removed from the computers, totally but the issue still persists. If ant is called directly ie java -jar /usr/share/ant/lib/ant-launcher.jar it runs fine ..... Unfortunalty this only happens on select computers, on my own machines this is not happening making this a hard bug to find the cause of .... Reproducible: Sometimes Steps to Reproduce:
A workaround btw is to remove ant-optional, but this will remove any functions that want special tasks such as antlr ....
can you submit the following? "emerge info" and "qpkg -I -v ant"
Please emerge ant-1.5.4 for now. 1.6.0 is moved into package.mask because there are too many problems with it. Reference bug # 42850
Emerge ant 1.6.1, your problems should be fixed.
