Hello, closing in on a final version of this gradle rework. There is an updated webrev in:
This fix has a number of cleanups that should help with developer "gradle sdk" times.
We added a new task: 'jdkZip' to create the zip that can be used to hand off our module build to the JDK. This step is no longer in the 'sdk' task resulting in a speed boost for most people. This change obsoletes the BUILD_MODULE_ZIP property. Note: it is possible to build a local JDK without using the zip at all....
When building the 'zips' task, there is no longer a need to include -P BUILD_JAVADOC=true, much to my relief as I have hated this flag for quite some time.
Give it a try :-)
