I'm in the process of developing a plugin. I created a Maven project from io.jenkins.archetypes:empty-plugin. The created POM contains:
<properties> <java.level>8</java.level>
If I change this to 11 hell breaks loose because on line 485 in the parent POM org.jenkins-ci.plugins:plugin:4.28 there is:
<maxJdkVersion>1.${java.level}</maxJdkVersion>
and 1.11 is not a proper Java version. Hence it was not the best decision to define maxJdkVersion like this.
The latest org.jenkins-ci.plugins:plugin:pom:4.29 contains the same declaration on the same line 485.
The same applies to org.jenkins-ci.tools:maven-hpi-plugin:3.19, lines 292, 293.

@markewaite Thx for the info. If such would have been mentioned on https://www.jenkins.io/doc/developer/tutorial/ and/or https://github.com/jenkinsci/theme-manager-plugin/blob/master/docs/developer-guide.md and/or as comment in the POM itself I wouldn't have even created an issue here.

Jenkins plugins can be developed with Java 11 but we retain java.level as 8 so that plugins developed with Java 11 can still be run on a Jenkins instance that is running Java 8. Greater than 50% of Jenkins controllers are still running Java 8. You want to be compatible with those controllers. Leave the java.level value at 8.
