[GitHub Actions](https://github.com/micronaut-projects/micronaut-core/actions) are used to build Micronaut Framework. If a build fails in `master`, check the [test reports](https://micronaut-projects.github.io/micronaut-core/index.html).

is the following:

GitHub Actions are used to build Micronaut Framework. If a build fails in master, check the test reports.

I don’t think the master branch is a thing any longer, and the link to test reports has problems. The test reports link links to https://micronaut-projects.github.io/micronaut-core/index.html which contains old test reports, there is a broken image link to http://micronaut.io/images/micronautlogo.svg and all the of the checkstyle links are currently 404’ing.

Ex:

https://micronaut-projects.github.io/micronaut-core/aop/checkstyle/index.html
https://micronaut-projects.github.io/micronaut-core/cli/checkstyle/index.html
https://micronaut-projects.github.io/micronaut-core/core/checkstyle/index.html
Etc...
