title: 'dependencies.dependency.version' is missing error, but version is managed in parent
body: <p>I have a maven project that contains several modules.  In Eclipse (Juno, with m2e) it seems to compile fine.  But when I do a maven install on one of the modules, the build fails immediately. </p>
  
  <p>Parent pom:</p>
  
  <pre><code>  &lt;groupId&gt;com.sw.system4&lt;/groupId&gt;
    &lt;artifactId&gt;system4-parent&lt;/artifactId&gt;
    &lt;version&gt;${system4.version}&lt;/version&gt;
    &lt;packaging&gt;pom&lt;/packaging&gt;
    &lt;name&gt;System 4 Parent Project&lt;/name&gt;
    &lt;modules&gt;
      &lt;module&gt;system4-data&lt;/module&gt;
       ...others...
    &lt;/modules&gt;
    &lt;properties&gt;
      &lt;system4.version&gt;0.0.1-SNAPSHOT&lt;/system4.version&gt;
      &lt;spring.version&gt;3.2.3.RELEASE&lt;/spring.version&gt;
      ... others...
    &lt;/properties&gt;
  
    &lt;dependencyManagement&gt;
      &lt;dependencies&gt;
        &lt;dependency&gt;
          &lt;groupId&gt;org.springframework&lt;/groupId&gt;
          &lt;artifactId&gt;spring-core&lt;/artifactId&gt;
          &lt;version&gt;${spring.version}&lt;/version&gt;
          &lt;scope&gt;runtime&lt;/scope&gt;
        &lt;/dependency&gt;
      ... lots of others ...
      &lt;/dependencies&gt;
    &lt;/dependencyManagement&gt;
  </code></pre>
  
  <p>Child pom:</p>
  
  <pre><code>  &lt;parent&gt;
      &lt;groupId&gt;com.sw.system4&lt;/groupId&gt;
      &lt;artifactId&gt;system4-parent&lt;/artifactId&gt;
      &lt;version&gt;0.0.1-SNAPSHOT&lt;/version&gt;
    &lt;/parent&gt;
    &lt;artifactId&gt;system4-data&lt;/artifactId&gt;
    &lt;dependencies&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;org.springframework&lt;/groupId&gt;
          &lt;artifactId&gt;spring-core&lt;/artifactId&gt;
          &lt;scope&gt;runtime&lt;/scope&gt;
      &lt;/dependency&gt;
      ... lots of others...
    &lt;/dependencies&gt;
  </code></pre>
  
  <p>When I build, I get the following output:</p>
  
  <pre><code>[ERROR] The build could not read 1 project -&gt; [Help 1]
  [ERROR]
  [ERROR]   The project com.sw.system4:system4-data:0.0.1-SNAPSHOT (C:\work\eclips
  e_workspaces\systemiv\system4-parent\system4-data\pom.xml) has 8 errors
  
  [ERROR]     'dependencies.dependency.version' for org.springframework:spring-cor
  e:jar is missing. @ line 16, column 16
  
  ... others omitted for clarity ...
  </code></pre>
  
  <p>I dont understand why it doesn't even attempt to compile.  Ive tried removing the runtime scope from parent and child, and it makes no difference.  Please help!</p>
