When I try to emerge eclipse-3.1_pre5 with java-1.5 (after disabling JVM test in the ebuild), I get javac error, BUT no error when launching ant from the /var/tmp/portage/(...)/ directory where the failling build.xml is located. I had exactly the same problem with junit, but I can't reproduce it anymore. Reproducible: Always Steps to Reproduce: 1. Edit eclipse-sdk-3.1_pre5 2. Set the sun-jdk-1.5.0.01 JVM with java-config 3. emerge =dev-util/eclipse-sdk-3.1_pre5 (note that xerces is already compiled with java-1.5.0.01) Actual Results: Had : (...) * Building GTK+ frontend (compile) -- see compilelog.txt for details [echo] Deleting jars to recompile...

Step 1 to reproduce is : Comment out # if (java-utils_is-vm-version-ge 1 5 0) ; then # die "${P} cannot be compiled with a 1.5.x VM, set your system VM to a 1.4.x VM." # fi in eclipse-sdk-3.1_pre5.ebuild
I fail to see that this is a solution to anything. You have disabled re-compilation of practically all of the platform because it does not work with the Sun JDK 1.5, which means the ebuild no longer builds Eclipse from source. The ebuild test for 1.5 was obviously put in explicitly for the reason that Eclipse 3.1.x cannot be compiled with Sun JDK 1.5 using our current setup. According to Billy Biggs of the Eclipse team, it is not a priority for the Eclipse people to have the system compilable with Sun JDK 1.5. I'm closing this as UPSTREAM for now, awaiting a long-term solution. We do not officially support Java 1.5 on Gentoo yet anyway.
