We are building the :front_end target when files change, but this doesn't seem to be broad enough to ensure we build on all changes. This CL updates the target to devtools_frontend_resources, which does seem to be a broader target. This CL also includes a drive-by fix so that the output is sent to stdout. Bug: 1098694 Change-Id: I1d02cc0226767377aa4729af3cf3a734ec774026 Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2278471 Auto-Submit: Paul Lewis <aerotwist@chromium.org> Reviewed-by: Tim van der Lippe <tvanderlippe@chromium.org> Commit-Queue: Tim van der Lippe <tvanderlippe@chromium.org>
