+          job.  That means you pushed one or more files that did not conform
+          to the formatting specified in .clang-format. That may be because
+          you neglected to run 'git clang-format' or 'clang-format' before
+          committing, or that your version of clang-format has an
+          incompatibility with the one on this
+          machine, which is:
+        SUGGESTION: |
+
+          To fix it, you can do one of two things:
+          1. Download and apply the patch generated as an artifact of this
+             job to your repo, commit, and push.
+          2. Run 'git-clang-format --extensions c,cpp,h,cxx,ipp develop'
+             in your repo, commit, and push.
