Is this working around a bug in gn? Can't we list all the targets?

[Jay Civelli, 2016/10/18 22:28:03]

We can... but there are a bunch and there are synthetic. Here is the list:

//services/ui/ws:mus_ws_unittests__isolate__write_deps
//services/ui/ws:_mus_ws_unittests__library
//services/ui/ws:mus_ws_unittests_apk__process_resources
//services/ui/ws:mus_ws_unittests_apk__java__compile_java__javac
//services/ui/ws:mus_ws_unittests_apk__java__compile_java__process_prebuilt__copy
//services/ui/ws:mus_ws_unittests_apk__create__package_resources
//services/ui/ws:mus_ws_unittests_apk__create__package
//services/ui/ws:mus_ws_unittests_apk__create_incremental_generate_manifest
//services/ui/ws:mus_ws_unittests_apk__create_incremental__package_resources
//services/ui/ws:mus_ws_unittests_apk__create_incremental__package

Sadly we cannot use mus_ws_unittests* in GN so it's either the full list or
//services/ui/ws/*

Ugh! Ok, keep what you have.
