Hi,
Now we use rat plugin to check apache header, it seems that our project can pass rat check on linux but failed on windows. If someone creates a pull request from his forked repo, we use travis-ci to run tests on different os without checking apache header. If we add apache header check in travis file(see [1]), it fails on some os. Can we add a new pipeline which is only used to check apache header on linux? I found that there many free continuous integration service at [2]. Shall we choose one of them?
