Grails 2.5.0 Maven Build Issues

Question

I'm trying to build a new Grails 2.5.0 application using Maven, but keep getting errors relating to the grails-maven-plugin.

    [ERROR] Failed to execute goal org.grails:grails-maven-plugin:2.4.4:clean (defau
lt-clean) on project grails_2.5.0_test: Execution default-clean of goal org.grai
ls:grails-maven-plugin:2.4.4:clean failed: java.lang.reflect.InvocationTargetExc
eption: org.codehaus.groovy.runtime.DefaultGroovyMethods.each(Ljava/util/Collect
ion;Lgroovy/lang/Closure;)Ljava/util/Collection; -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal o
rg.grails:grails-maven-plugin:2.4.4:clean (default-clean) on project grails_2.5.
0_test: Execution default-clean of goal org.grails:grails-maven-plugin:2.4.4:cle
an failed: java.lang.reflect.InvocationTargetException
        at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor
.java:224)

Steps to reproduce:

1. grails create-app test
2. grails create-pom test
3. Updated the maven-clean-plugin dependency from 2.4.0 to 2.4.1 in pom.xml
4. mvn clean install

I'm running this on JDK 1.7.

The same example works fine with Grails 2.4.4. Am I missing something or is this a bug in 2.5.0?

Answer 1

A new version of the Grails Maven plugin (2.4.6) has been released which fixes this issue. I have tested this and can confirm that issue is resolved.
