Adopt OpenJDK is widely used in the Jenkins project.  You're also welcome
to use other OpenJDK implementations.  Licensing restrictions on recent
Oracle JDK 8 versions have made it very rarely used in the Jenkins project.

Best to use JDK 8 for all purposes related to Jenkins.

Yes, that was it. I'm compiling on OpenJDK 11.
Using 2.164.1 works now even with parent 
POM 3.56

Thank you.

I receive that message when I'm compiling with Java 11 but using a Jenkins
version before 2.164.  The first Jenkins LTS to support Java 11 compilation
is Jenkins 2.164 (as far as I know)  I've learned to type:

$ mvn clean -Djenkins.version=2.164.3 verify

Eventually, I will update the plugins where I use that technique so that
they require Jenkins 2.164 or newer as their minimum version.  Jenkins
2.164 is over a year old.

Re: I'm working on a new plugin and when I try to run it I get the following error

[Daniel Anechitoaie]

Hmm, yeah, I had a small brainfart. For some reason I was thinking in 
decimal and was seeing 3.6 as 3.60 which in my mind was more recent than 
3.56 (which is the latest 3.x version)/

So now with 


org.jenkins-ci.plugins
plugin
3.56





And 


1.8
8
2.121.1




I get

[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile 
(default-compile) on project my-plugin: Compilation failure
[ERROR] java.nio.file.NoSuchFileException: 
/Users/daniels/Work/my-plugin/target/classes/META-INF/annotations/hudson.Extension

Should I just go to latest Jenkins and the 4.0 beta parent pom?

This is very old. Try using the latest 3.x, and for the newer LTS line
you may need to use a 4.0 beta.
