Targeting gradle javadoc cleans and recompiles our java code

[Kirk Lund <kl...@pivotal.io>]

I'm trying to execute javadoc and only javadoc.

But when I attempt to do so by invoking this...

./gradlew geode-core:javadoc

...our gradle deletes the geode-core/build directory, recompiles java, and
other tasks before finally executing javadoc.

Why is it doing this? Can't we change our gradle build to behave as
expected?

Thanks,
Kirk
