| RE: [platform-ant-dev] custom ProjectHelper |
Browsing the Ant user manual I noticed that this feature isn't documented anywhere but in the source code ;-) The same goes for the ant.home property which is set by Ant's command line frontend and is used by the core <exec> task.
This makes it a little bit unclear whether this is really a bug in the Ant plugin or not. But if any exposed behaviour differing from Ant's command line frontend is regarded as a bug, then this clearly is one.
So for documentation I have to point you to the source files, where the classes org.apache.tools.ant.ProjectHelper and org.apache.tools.ant.helper.ProjectHelperImpl should capture everything about the feature.
Since I mentioned the ant.home property which isn't set I thought I'd ask about that as well. Do you think that future versions of the plugin will encapsulate a complete Ant distribution (or as an alternative let the user specify his Ant installation directory) which would let you properly set the ant.home property?
