The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/2dfa922ea82356a8ac56537225ed27234d0f6df2 commit 2dfa922ea82356a8ac56537225ed27234d0f6df2 Author: Albert Chaulk <achaulk@google.com> Date: Wed Jun 13 22:18:15 2018 Fix flaky build caused by unintentional build variable inclusion //extensions/common/api/schema.gni defines extensions_api_uncompiled_sources During review, this variable was added to the common build file, but the error only occurs for clean builds, otherwise you would get a working build with flaky runtime behaviour The compiler attempts to find the common subdir between chromecast/common/extensions_api and extensions/common/api and puts the generated file in the root Merge-With: eureka-internal/171973 Bug: 852454 Test: Local clean build works Change-Id: Ic18a4a94c8c52b19a33750772fe855ce486eeec8 Reviewed-on: https://chromium-review.googlesource.com/1099373 Commit-Queue: Albert Chaulk <achaulk@google.com> Reviewed-by: Luke Halliwell <halliwell@chromium.org> Reviewed-by: Daniel Nicoara <dnicoara@chromium.org> Cr-Commit-Position: refs/heads/master@{#567017} [modify] https://crrev.com/2dfa922ea82356a8ac56537225ed27234d0f6df2/chromecast/common/extensions_api/BUILD.gn
