Steven Rowe updated LUCENE-3337:
--------------------------------
Attachment: LUCENE-3337.patch
This version of the patch moves uptodate checks and targets to build jars for
other modules to {{lucene/contrib/contrib-build.xml}}. All Solr & Lucene
modules are now covered. The Lucene core build now has a {{jar-core}}
specialization that avoids creating the jar when it's already up-to-date -
previously when running {{ant test}} from {{solr/}}, the Lucene core jar was
built 41 times, because the manifest was newer each time...
My build times now:
||task||trunk||Robert's patch||My patch w/property passing optimizations||
|ant example (clean checkout)|180s|119s|52s|
|ant example (already compiled)|132s|61s|27s|
I think this should be committed; further changes can be made with more patches.
> avoid building jar files unless necessary in build

> test)
