How to create bamboo plugin in java11

tupatel

I am creating bamboo plugin with java11 and maven project.

mvn clean install is returning success status with below NPE

<span>java.lang.NullPointerException
    at aQute.bnd.osgi.Processor.quote(Processor.java:1322)
    at aQute.bnd.header.Attrs.append(Attrs.java:404)
    at aQute.bnd.header.Parameters.append(Parameters.java:172).......</span>

when tried uploading plugin in bamboo 6.8.1 with java11 then it throws failure error.

Firstly tried on hello world plugin as well as per pom.xml mentioned in URL:https://community.atlassian.com/t5/Bamboo-questions/Create-bamboo-plugin-tutorial/qaq-p/686456

<span><properties></span>

 <span><atlassian.spring.scanner.version></span><span>1.2.6</span><span></atlassian.spring.scanner.version></span>
 <span><atlassian.plugin.key></span><span>${project.groupId}.${project.artifactId} 
 </span><span></atlassian.plugin.key></span>
<span></properties></span>

expecting bamboo plugin should get build without any error and should get upload successfully.
