srcFileLists was an ill-fated attempt to deal with generators that produce a set of java sources that is not known ahead of time. For example, the list of files produced by protoc depends on the package statement in the .proto file. srcFileLists put the list of generated files into a file, which was then passed to javac using the @file syntax. This worked, but it was too easy to cause missing dependencies, and will not work well in a future distributed build environment. Switch to putting generated sources into a jar, and then pass them jar to javac using -sourcepath. Test: m checkbuild Change-Id: Iaab7a588a6c1239f7bf46e4f1b102b3ef517619b
