[ http://jira.codehaus.org/browse/MNG-2196?page=all ]
John Casey closed MNG-2196:
---------------------------
Resolution: Fixed
see it0103.
Vincent, see below for some comments I have related to your specific POM.
The fix involved adding a raw-project cache to the project builder. MNG-2054
was the flip-side of this problem, in that it had a problem that came from
using the processed-project cache for assembling the project lineage that would
eventually be used for inheritance...in that case, projects which had already
had inheritance operations performed on them were causing multiple inheritance
of the same configuration from ancestor POMs.
In this case, turning off that caching means that POMs which have broken
<relativePath/> links to the parent POM, and whose parent POMs are not in the
repository, will not be able to find their parent in a multimodule build - even
though the parent has been cached as part of the current build process. To fix
this, I've implemented raw-project caching, which are the project instances
without interpolation, inheritance, etc. operations performed on them. This
allows assembleLineage(..) to lookup and use these POMs, and have subsequent
inheritance operations succeed without injecting the same config multiple times.
Vincent, although this use case has been fixed in SVN, I'd strongly suggest you
add a *relativePath* element to the testdata POM's parent section, so it can be
built in isolation, even if the parent POM isn't in the repository.
