Revision 1.30 - (hide annotations) (download)
Sun Dec 3 17:42:53 2006 UTC (8 years ago) by betelgeuse
Branch: MAIN
Changes since 1.29: +37 -24 lines
Rewrote java-pkg_getjars to only accept two arguments (--build-only and java-config --classpath-argument). The previous handling for multiple packages was broken. Also documented java-pkg_dojavadoc.
