Speed up ivy resolution in builds with clever caching
-----------------------------------------------------
Key: MAPREDUCE-1114
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1114
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: build
Affects Versions: 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
An awful lot of time is spent in the ivy:resolve parts of the build, even when
all of the dependencies have been fetched and cached. Profiling showed this was
in XML parsing. I have a sort-of-ugly hack which speeds up incremental compiles
(and more importantly "ant test") significantly using some ant macros to cache
the resolved classpaths.
