1. Bundle static_java_header_libs during turbine-classes.jar if necessary. This can be improved if we have the ability to merge jars on the fly. 2. Copy sdk/stubs-classes.jar to sdk/stubs-classes-header.jar, and Use .KATI_RESTAT to cut un-necessary targets rebuilt. 3. Copy prebuilt-classes.jar to prebuilt-classes-header.jar since Turbine doesn't apply to prebuilt. 4. Run jarjar after Turbine compilation, otherwise downstream targets won't find corresponding symbols. 5. Change classes.jar in -classpath used in Desugar to classes-header.jar. 6. Change legacy-libs in Proguard from classes.jar to classes-header.jar. 7. Add .KATI_RESTAT for turbine-classes.jar, and remove IJAR. 8.boot.art is re-generated during the incremental rebuild since javalib.jar got re-generated. Then boot.art re-triggered lots of downstream targets to be rebuilt. So we add .KATI_RESTAT for javalib.jar to prevent downstream to be rebuilt. The ziptime & commit-change-to-toc operation for javalib.jar(small) didn't bring too much overhead when we build from clean state. Next step: specify static_java_header_libs in -classpath, and merge jars at the end. touch frameworks/base/core/java/com/google/android/util/Procedure.java && time m time: 1m58s (794 -> 49 targets) m clean && time m java time: 9m34s Bug: b/64308460 Test: m clean && m checkbuild Change-Id: Iefcc234405b9f461b6882c06bba15e21fa783d28
