on Android O - mm cmd fails in /framework/base

[rashmi...@gmail.com]

On Android version 8.1.0 project specific build with mm cmd is failing in /framework/base

[100% 1/1] out/soong/.bootstrap/bin/soong_build out/soong/build.ninja

ninja: error: 'out/host/linux-x86/framework/host-libprotobuf-java-full.jar', needed by 'out/host/common/obj/JAVA_LIBRARIES/platformprotos_intermediates/classes-full-debug.jar', missing and no known rule to make it

12:55:19 ninja failed with: exit status 1

Please help me to resolve this.

Have you run `mma` successfully before running `mm`? `mm` can really only handle rebuilds, since it doesn't attempt to build any required dependencies.

mm compiles all modules in a directory, you are missing a dependency of one of the modules. This is pretty common because regular builds do not compile tests or their dependencies. You can run 'hmm' to see commands that do take dependencies into account. In this case, you want 'mma':

λ hmm | grep " mm"

- mm:        Builds all of the modules in the current directory, but not their dependencies.

- mmm:       Builds all of the modules in the supplied directories, but not their dependencies.

             To limit the modules being built use the syntax: mmm dir/:target1,target2.

- mma:       Builds all of the modules in the current directory, and their dependencies.

- mmma:      Builds all of the modules in the supplied directories, and their dependencies.
