Problem found with: binding-parent, odlparent .. more effected

Message: 

Java11 compile fails with ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.10.4:jar (attach-javadocs) on project sdnr-wt-apigateway-provider: MavenReportException: Error while generating Javadoc: 
[ERROR] Exit code: 1 - javadoc: error - The code being documented uses modules but the packages defined in http://docs.oracle.com/javase/8/docs/api/ are in the unnamed module.

POM configuration: <maven.javadoc.skip>false</maven.javadoc.skip>.

Analysis: Parent are forcing to use "old maven-javadoc-plugin", what is working for Java8

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.10.4</version>

Solution: 

Change related pom files to version:

<artifactId>maven-javadoc-plugin</artifactId>
<version>3.1.1</version>

• This version is used in ODL parents and should be used for ONAP Guilin
• It is working for Java8 and Java11 builds
