According to my test, the Travis ARM CI is not ready. For example: 1. Java8 support is missing. https://travis-ci.community/t/about-the-arm-cpu-architecture-category/5336/4 2. Cache function is not supported. https://travis-ci.community/t/no-cache-support-on-arm64/5416
The compile job ran timeout without cache after 50 min. It's not a good time to use travis ARM CI at the moment. While OpenLab doesn't have any limitations (It can provide 16U16G VMs with no time limitation for CI job). Just FYI, any response is welcome. Thanks. Regards.
