title: Existing Manifest (build error)
body: <p>I'm trying to add splashscreen on my application. I clean build the program but I selected the wrong file. Now I edited the VM Option and clean build again the second time, now I'm getting this error:</p>
  
  <blockquote>
    <p>C:\Users\User\Documents\NetBeansProjects\ProjectInOOP\nbproject\build-impl.xml:975:
    Existing manifest
    C:\Users\User\Documents\NetBeansProjects\ProjectInOOP\build\null209371772
    is invalid BUILD FAILED (total time: 5 seconds)</p>
  </blockquote>
  
  <p>It's pointing to this part:</p>
  
  <pre><code>&lt;target depends="init,-do-jar-create-manifest,-do-jar-copy-manifest" if="do.archive+main.class.available" name="-do-jar-set-mainclass"&gt; &lt;manifest file="${tmp.manifest.file}" mode="update"&gt; &lt;attribute name="Main-Class" value="${main.class}"/&gt; &lt;/manifest&gt; &lt;/target&gt;
  </code></pre>
  
  <p>But when I remove this part on manifest, it can clean build again:</p>
  
  <blockquote>
    <p>SplashScreen-Image: splashPack/flash.gif</p>
  </blockquote>
  
  <p>Anyone? Or is there other alternative? I'm using netbeans.</p>
