Use "resemblejs" dep This fixes it so it uses the resemblejs dependency from gerrit core. This is because resemblejs was not being injected into the plugin thus failed to load. I tested this by doing: bazel build plugins/image-diff Then deploying (and uploaded a png file to test) Bug: Issue 9911 Change-Id: I239d93a4352429ae3b09eb132cbf159c67f0913e
