Description

Building module org-apache-sling-jcr-resource fails, and during test phase this is the error:
 
Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test failed.: NullPointerException 
 
java version "11.0.6" 2020-01-14 LTS
Apache Maven 3.6.3 
 
I tried to change parent to org.apache.sling:sling-bundle-parent:pom:40 but then building fails because of the errors reported by maven-enforcer-plugin.
