3. Verify Maven compatibility

Modify your pom.xml, change “grails-maven-plugin” version to 1.0. (According to http://www.grails.org/Maven+Integration)

<build>
  <pluginManagement />
  <plugins>
    <plugin>
      <groupId>org.grails</groupId>
      <artifactId>grails-maven-plugin</artifactId>
      <version>1.0</version>
      <extensions>true</extensions>
      […]

Does it build now ? Yes !
