Avtually I wouldn't make core depend on it but tell people to use this antlib if they need permissions support. This antlib may need to come with its own version of a java task for things to work. > I haven't checked if we already have such dependencies and if not, > whether it's OK to add such a dependency. No, we haven't. In the beginning Ant has been very proud of the fact that you could bootstrap it with a pretty trivial shell script and the only dependencies except for the JDK has been an XML parser - this has been before JAXP became part of the Java class library, i.e. Java prior to 1.3. Of course the pretty trivial shell script is not so trivial anymore, but it still holds that all pieces of Ant we consider core do not have any external dependency at all. Personally I appreciate this property, but that may just be me. > Furthermore, to make this usable/backward compatible, we would have to > use the same package namespace for this permissions stuff in that new > antlib jar, which I think can cause issues when the same package > "org.apache.tools.ant.types" is now loaded/available in 2 separate > CodeSources (jars) - one in core Ant jar and one in this antlib jar. I didn't mean the Antlib to be backwards compatible, but rather to offer it and tell people to switch over to it. It would be the first time we'd remove a core feature of Ant completely, though, so we may need to discuss whether there is a better migration path. We have moved some source code management tool specific tasks to antlibs in the past, but never a core part.
