It looks like buildmagic is incompatible with ant 1.7 because even though I have updated the version check to allow 1.7, it seems as though the ant.version property is not set:
== Executing 'most' in module 'main'...
/Users/svn/JBossHead/jboss-head/tools/etc/buildmagic/buildmagic.ent:31: Unsupported Ant version:
Please install a version which is compatible with Ant 1.5 or 1.6.
Total time: 1 second
I have to add -Dant.version="Ant version 1.7" on the command line to get past the version check. I'm half tempted to just drop the version check rather than hack into the buildmagic code.
