[FIXED] How to setup a java 11 based spring boot pipeline on bitbucket?

Issue

Build fails with "invalid target release: 11" message.

After a commit to bitbucket, a pipeline job starts automaticly but fails with

Full Error Message:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project sms-commons: Fatal error compiling: invalid target release: 11 -> 

How to enable java 11 support?

image: maven:3.3.9

pipelines:
  default:
    - step:
        caches:
          - maven
        script: # Modify the commands below to build your repository.
          - mvn -B verify # -B batch mode makes Maven less verbose
          - mvn clean install

I expect a successfull build, but as I wrote the build job fails.

Solution

You need to use a newer version of the maven Compiler Plugin

org.apache.maven.plugins maven-compiler-plugin 3.8.0

And you need a maven Docker image that is providing java 11 for example maven:3-jdk-11
