Subject RE: Build data in built artifacts
Date Wed, 23 Aug 2006 16:35:48 GMT
Since there are multiple jars, maybe it makes sense for each of the
different modules to have a META-INF/openjpa-revision.properties file,
and then have OpenJPAVersion print out the information for each of said
resources in the classpath, if they're not the same.
