[jira] [Commented] (MENFORCER-156) Upgrading maven-enforcer-plugin from 1.2 to 1.3 breaks maven-assembly-plugin

["Michael K (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MENFORCER-156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15174063#comment-15174063 ] 

Michael K commented on MENFORCER-156:
-------------------------------------

Sorry for the delay.

The bug in our project has been found. It was a problem with inheritance issues. Nothing to open a ticket for here.

Conclusion:
Set the maven-enforcer-plugin version to 1.4.1 and the maven-assembly-plugin version to 2.6; check all other plugin version and update them; don't forget to check the effective pom. Should work.

> After upgrading m-e-p from 1.2 to 1.3 the maven-assembly-plugin generates the following error:
> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single (assemble) on project extjars: Execution assemble of goal org.apache.maven.plugins:maven-assembly-plugin:2.4:single failed. NullPointerException -> [Help 1] 
> Downgrading to m-e-p 1.2 makes the assembly work again.
> Sample pom & assembly that expose the error attached.
> When called via:
>     mvn -Dplugins.maven-enforcer-plugin.version=1.2
> a zip file is generated as expected, when called via
>     mvn -Dplugins.maven-enforcer-plugin.version=1.3
> (or without argument) you will get the NPE.
