This action sets up a java environment for use in actions by:
|
|
|
|
- optionally downloading and caching a requested version of java by version and adding to PATH. Default downloads are populated from the [Zulu Community distribution of OpenJDK](http://static.azul.com/zulu/bin/)
|
|
- registering problem matchers for error output
|
