As far I understand Apache Infra recommends to migrate Continuous Integration builds from Travis to GitHub Actions.
I've added initial configuration for GitHub Actions for APR project: https://svn.apache.org/repos/asf/apr/apr/trunk/.github/workflows/ GitHub supports Linux, macOS and Windows runners. Action runners status is available on GitHub: https://github.com/apache/apr/actions (any GitHub account is required to see logs) Suggestions and improvements are welcome. -- Ivan Zhakov
