Summary: Hanlde servral ProjectHelper and default file support
Product: Ant
Version: 1.8Alpha (nightly)
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Core
AssignedTo: [email protected]
ReportedBy: [email protected]
Here is a patch as discussed here:
http://mail-archives.apache.org/mod_mbox/ant-dev/200908.mbox/%[email protected]%3e
I didn't committed it directly as there will be a release really soon and I
don't want to break anything and then force this new feature to be in that
release.
So there is now a ProjectHelperRepository which is responsible to gather every
declared implementation of ProjectHelper in the classpath. The default
ProjectHelper will be the first found in the classpath. And this repository
will never be empty as the ProjectHelper2 will always be added at the last
position.
I did some a few test with another implemetation of ProjectHelper that read
groovy files. Everything works like a charm execept one case:
* simple launch of ant : the default helper is the groovy one : OK
* ant -f build.xml : the helper used is the ProjectHelper2 : OK
* in the build.gant I put an ant task without specifying any build file: the
build.xml is taken: OK
* in the build.gant I put an gant task without specifying any build file: I
got:

I didn't look closely but it is probably a bug in my groovy frontend.
