Description

Ocasionally buildit fail to build. The command I used is something like this:

bin/buildit localhost prototype

output is following:

BUILD FAILED
/home/lynus/java_staff/JikesRVM_test/build.xml:1675: Compile failed; see the compiler error output for details.

This failure does not happend each time I execute the script. But I noticed that it's likely to happend if I execute 'ant purge' or 'ant real-clean' before this script.
