title: Your active platform is: default_platform, but the corresponding property "platforms.default_platform.home" is not found
body: <p>Im currently developing JavaFX applications. I used Netbeans 7.4 before but now I switch to Netbeans 8.0.2. After running my project with the new IDE, an error occured saying:</p>
  
  <pre><code>C:\projects\client\QueueBoard\nbproject\build-impl.xml:87: The J2SE Platform is not correctly set up.
  Your active platform is: default_platform, but the corresponding property "platforms.default_platform.home" is not found in the project's properties files. 
  Either open the project in the IDE and setup the Platform with the same name or add it manually.
  For example like this:
  ant -Duser.properties.file=&lt;path_to_property_file&gt; jar (where you put the property "platforms.default_platform.home" in a .properties file)
  or ant -Dplatforms.default_platform.home=&lt;path_to_JDK_home&gt; jar (where no properties file is used)
  BUILD FAILED (total time: 0 seconds)
  </code></pre>
  
  <p>How do you resolve this? </p>
