title: Failed to read artifact descriptor for maven-resources-plugin
body: <p><strong>Stage</strong>:</p>
  
  <p>I am trying to compile a Maven project in Eclipse (Spring Tool Suite, version: <code>3.2.0.RELEASE</code>).</p>
  
  <p>Each project compilations throws this:</p>
  
  <pre><code>Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5
  Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5
  </code></pre>
  
  <p>How can I solve it?</p>
