With the patch against r1567529, `mvn clean install -DskipTests=true -f core/pom.xml` passes compilation.

> When testing with a command `mvn -f core/pom.xml clean install -Dtest=<TestCase>`, maven complains NPE as below
> {code}
> Caused by: java.lang.NullPointerException
> 	at java.util.Hashtable.put(Hashtable.java:394)
> 	at org.codehaus.groovy.maven.plugin.execute.GroovyMavenProjectAdapter$EvaluatingProperties.put(GroovyMavenProjectAdapter.java:162)
> 	at java.util.Properties.setProperty(Properties.java:143)
> {code}
> It looks like groovy-plugin raise the issue. 
> {code}
>         <groupId>org.codehaus.groovy.maven</groupId>
>         <artifactId>gmaven-plugin</artifactId>
>         <version>1.0</version>
> {code}
> But changing to v1.4 or other version, found at http://docs.codehaus.org/display/GMAVEN/Home, shows that standard maven repository doesn't have those version.
> {code}
> Could not find artifact org.codehaus.groovy.maven:gmaven-plugin:pom:1.1 in central (http://repo.maven.apache.org/maven2)  
> {code}
> This doesn't block the compilation actually, because compilation process can be done via `mvn clean install` without a problem. 
> BTW, it seems that gmaven is discontinued. 
> {code}
> GMaven provides integration of Groovy into Maven. This project has been discontinued since the structure doesn't work well with how Groovy's invokedynamic releases.
> {code}
