I do have some documentation posted on how to debug slow issues like this: https://android.googlesource.com/platform/build/soong/+/master/docs/perf.md -- It can definitely be caused by $(shell) commands in Android.mk files, but from the first log here, you may also be hitting a known issue: https://android.googlesource.com/platform/build/soong/+/master/docs/perf.md#android-8_1-oreo-mr1
You may find it faster to use `mma` rather than `mm` over time, since the results can be shared between more different invocations (though some of the regen and loading steps are slower). - Dan On Wed, Apr 4, 2018 at 11:45 AM Jacob Abrams <[email protected]> wrote: > It's not a Google issue.
