 ## Automatic download from Oracle
-**Attention:** Back in the days this role would download all the JDKs directly from the Oracle site. Oracle cut this possibility step by step. Now you cannot download any version of JDK 8 anymore without Oracle login. For JDK 11 you can only download one older version. JDK 12 can be downloaded at the moment.

 Since this changes non-deterministically every time Oracle releases a new Java version, you should not rely on it. I recommend downloading the JDK manually and installing it by this role.
