precommit, java8 and Solr 5.x
Is there a magic flag to convince the precommit step to allow Java 8
constructs (lambdas in this case) when compiling a 5x version? I need
to backport some code.
I tried this:
ant -Djavac.source=1.8 -Djavac.target=1.8 -Dsource=1.8 precommit
and
ant -Djavac.source=1.8 -Djavac.target=1.8 -Dsource=8 precommit
to no avail. It all compiles fine, but generates this error:
-ecj-javadoc-lint-src:
.
.
.
[ecj-lint] Lambda expressions are allowed only at source level 1.8 or above
Meanwhile I'll dig of course.
Thanks,
Erick

Thanks. I think that's also the javac.source, but specifying it fully
doesn't change the behavior. I did manage to get it to work just now
so I'm good.
Best,
Erick

Have you tried -Dant.build.javac.source=1.8? Based on
http://ant.apache.org/manual/running.html#sysprops (though maybe those
are environmental properties).
