Description

This morning, we accidentally merged (on github' UI) one pull request to social client master. When I realized that, I reset --hard to the commit that is before the mis-merged commit and then force push (rewrite commit history).

After that, we met this problem:


  1. The mis-merged commit is still there: https://ci.exoplatform.org/job/social-client-master-ci/changes SCL-14 | Switch to use TestNG instead of JUnit (commit: ad11e95eba2343fb8c14c04be981f74bc3035465) — hoatlevan / detail

  2. failed build with this: https://ci.exoplatform.org/view/%C2%B0%20IT%20%C2%B0/job/social-client-master-it/42/

    This is a matrix build. The parent went fine
