title: Hadoop Build failed (Hadoop src 2.2.0) on Windows 7, Maven 3.1.1, Jdk 1.7.0_45
body: <p>Though I am running 
  <strong>Ms-SDK 7.1</strong> command prompt in <strong>Admin mode</strong>, I am getting <strong><em>hadoop.dll access denied error</em></strong> causing hadoop build failure.</p>
  
  <pre><code>[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8
  .1:jar (module-javadocs) on project hadoop-common: ArchiverException: Error whil
  e creating archive: Problem creating jar: C:\hdfs\hadoop-common-project\hadoop-c
  ommon\target\hadoop-common-2.2.0\bin\hadoop.dll (Access is denied) 
  </code></pre>
  
  <p>I thought it might be problem with JDK version so I have uninstalled jdk1.7. and insatlled jdk1.6.0_45 but still I'm getting permission error. </p>
  
  <p>Can I simply avoid hadoop-common module and install other?</p>
