Fix fragile assumptions about build toolchain. (attempt #2)
This CL resubmits a fixed version of commit
e2a8da26833be50489a82fed87d0896bd3496709.
This CL applies the following changes:
- explicitly set the path where desugar will dump temporary class files.
This ensures that the system property is set before it is read during
InnerClassLambdaMetafactory.<clinit>. Before this CL, the system
property was set by Desugar.createAndRegisterLambdaDumpDirectory(),
which may run too late.
- explicitly specify -source 1.8 for droiddoc's javadoc run.
Previously, the command used the language version of the build
toolchain, which might fail due the backward-incompatible restrictions
imposed by the proposed module system.
Some Android build targets use LOCAL_JAVA_LANGUAGE_VERSION 1.7,
but droiddoc combines sources from multiple build targets and there
where no backwards incompatible changes in 1.8, so it should be fine
to use 1.8 for code from either language level.
