Hi  
I am trying to integrate my jenkins to nexus reporting manager which I have installed in another Virtual machine using java 11.  
I am getting following error while test connection.

Sorry, but we do not support running on Java 11 yet.  
NXRM3 requires Java 8 runtime environment - this is described in [System Requirements](https://help.sonatype.com/repomanager3/system-requirements#SystemRequirements-Java)

So are you saying the Jenkins plugin (Jenkins Nexus Platform Plugin) requires Java 8?  
Nexus3 is running on Java 8 while Jenkins on a separate server is running Java 11.

```
[mc@docker3]$ docker exec -it nexus3 /bin/bash
bash-4.4$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

[mc@jenkins]$ java -version
openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)
```
