I’m using Maven 2.2 with Grails 1.2.1. When trying to run the “integration-test” target, I get some cryptic warnings, which I can’t figure out how to resolve …

davea-mbp2:socialmediaproxy davea$ mvn integration-test

[INFO] Scanning for projects…

[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

Here is the part of my pom.xml the warnings are referring to …

<!-- Grails defaults to Ehache for the second-level Hibernate cache. -->

      <!-- We have JCL-over-SLF4J instead. -->
      <exclusion>
          <artifactId>commons-logging</artifactId>
      </exclusion>
  </exclusions>
    </dependency>

Any ideas how i can solve these? Thanks, – Dave

    Just a misconfiguration in your pom.xml exclusions – you need to add the groupId entries. I don’t know exactly what they need to be (possibly javax.jms) but just replace the fixme as necessary.

    <dependency>
      <groupId>net.sf.ehcache</groupId>
      <artifactId>ehcache-core</artifactId>
      <version>1.7.1</version>
  <exclusions>
      <exclusion> <!-- line 33 -->
          <groupId>fixme</groupId>
          <artifactId>jms</artifactId>
      </exclusion>
      <exclusion> <!-- line 36 -->
          <groupId>fixme</groupId>
          <artifactId>servlet-api</artifactId>
      </exclusion>

      <!-- We have JCL-over-SLF4J instead. -->
      <exclusion>
          <groupId>fixme</groupId>
          <artifactId>commons-logging</artifactId>
      </exclusion>
  </exclusions>
    </dependency>
