> > QUESTION 6 : This is a AWS Java SDK related problem and I think it has > something to do with the pom.xml > When I run *mvn compile*, it has error like this :
Execution display-info of goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M1:enforce failed.: NullPointerException Part of my pom.xml look like this <parent> <groupId>org.jenkins-ci.plugins</groupId> <artifactId>plugin</artifactId> <version>3.18</version> </parent> <artifactId>external-workspace-manager</artifactId> <version>1.1.3-SNAPSHOT</version> <packaging>hpi</packaging> <properties> <jenkins.version>2.60.3</jenkins.version> <java.level>8</java.level> <argLine>-Xmx1024m</argLine> </properties> and the AWS Java SDK property was copied from ec2-plugin pom.xml. it looks like <dependency> <groupId>org.jenkins-ci.plugins</groupId> <artifactId>aws-java-sdk</artifactId> <version>1.11.457</version> </dependency> And the pom.xml in ec2-plugin looks like <parent> <groupId>org.jenkins-ci.plugins</groupId> <artifactId>plugin</artifactId> <version>3.25</version> </parent> I tried upgrade my plugin version to 3.25, but didn't work, does anyone know what's the potential problem ?
