Execution default-clean of goal org.grails:grails-maven-plugin:2.4.4:clean failed

[mmaryo]

Hi,

I can't use maven because of an error during clean.

To reproduce :

Java 8
Grails 2.5.0
New project

execute :
grails create-pom test

then :
mvn clean install package

the output :
[INFO] Scanning for projects...

So I changed the maven-clean-plugin from 2.4.0 to 2.6.1

then execute :
mvn install package

the output :

Is there a solution ?
Thanks

In the mean time, a new version of grails-maven-plugin is released that is compatible with Grails 2.5.1. You can now work around the second reported error by changing the generated POM to use version 2.4.6 of grails-maven-plugin.

The wrong version numbers causing both errors originate from grails-core/grails-resources/src/grails/templates/maven/project.pom.
