title: Properties in parent definition are prohibited in the intellij maven on my mac osx
body: <p>I have a question about my maven configuration on my MAC Intellij. I get an error that ${a-web.version} "properties in parent definition are prohibited" within parent tag in child POM.xml and that properties is defined in parent POM.xml.
  But this same configuration works well on my Windows Intellij.</p>
  
  <p>Below is my parent POM.xml.</p>
  
  <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
  http://maven.apache.org/maven-v4_0_0.xsd"&gt;
     &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
     &lt;groupId&gt;***&lt;/groupId&gt;
     &lt;artifactId&gt;a-web&lt;/artifactId&gt;
     &lt;packaging&gt;pom&lt;/packaging&gt;
     &lt;version&gt;${a-web.version}&lt;/version&gt;
     &lt;name&gt;a-web project&lt;/name&gt;
     &lt;url&gt;http://***&lt;/url&gt;
  
     &lt;properties&gt;
         &lt;a-web.version&gt;1.0.0&lt;/a-web.version&gt;
     &lt;/properties&gt;
  
     &lt;modules&gt;
         &lt;module&gt;a-core&lt;/module&gt;
         &lt;module&gt;a-web&lt;/module&gt;
     &lt;/modules&gt;
  &lt;/project&gt;
  </code></pre>
  
  <p>And this is my child POM.xml that configure a parent block.</p>
  
  <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
  http://maven.apache.org/maven-v4_0_0.xsd"&gt;
      &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
      &lt;parent&gt;
          &lt;artifactId&gt;a-web&lt;/artifactId&gt;
          &lt;groupId&gt;***&lt;/groupId&gt;
          &lt;version&gt;${a-web.version}&lt;/version&gt;
          &lt;relativePath&gt;../&lt;/relativePath&gt;
      &lt;/parent&gt;
  
      &lt;artifactId&gt;aweb-web&lt;/artifactId&gt;
      &lt;version&gt;${a-web.version}&lt;/version&gt;
      &lt;packaging&gt;war&lt;/packaging&gt;
      &lt;name&gt;aweb-web&lt;/name&gt;
  &lt;/project&gt;
  </code></pre>
  
  <p>I've tried many methods from stackoverflow, but no one can fix it. I want to know why this Maven config have different behaviour in Mac and windows and how to fix it.</p>
