hi all,
when i want to make HELIX i get this error :


set-buildinfo-vars:

BUILD FAILED
/home/public/p4/GNS/ZimbraServer/build.xml:564: The following error occurred while executing this line:
/home/public/p4/GNS/ZimbraServer/build.xml:345: No supported regular expression matcher found

Most probably you have old version of ant. You could check it with "ant -version"
