Upgrading groovy-all dependency to 2.5

Question

I'm trying to upgrade groovy-all from 2.3.x to 2.5.x, but I noticed that they no longer provide a groovy-all jar and instead provide a super POM that lists out all the groovy libraries as dependencies. Previously, this is what I had in my parent pom:

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <version>2.3.7</version>
      </dependency>
..
    </dependencies>
  </dependencyManagement>

And in my child pom:

  <parent> .. </parent>
  <dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-all</artifactId>
  </dependency>

This worked fine -- now I'm trying to upgrade to 2.5.x with these changes: parent pom:

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <version>2.5.8</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
..
    </dependencies>
  </dependencyManagement>

And child pom:

<parent> .. </parent>
<dependency>
  <groupId>org.codehaus.groovy</groupId>
  <artifactId>groovy-all</artifactId>
  <version>2.5.8</version>
  <type>pom</type>
</dependency>

However, now I'm getting this error:

Unable to list entries for jar: /Users//.m2/repository/org/codehaus/groovy/groovy-all/2.5.8/groovy-all-2.5.8.pom: error in opening zip file -> [Help 1]

How can I import the dependencies of this "all" pom using maven? Should I be changing something in the pom.xml files?
