View source for FAQ How do I add a builder to a given project?

To register the eScript builder for a given project, add the builder to the project&#146;s
build specification as follows:
<pre>
   private void addBuilder(IProject project, String id) {
      IProjectDescription desc = project.getDescription();
      ICommand[] commands = desc.getBuildSpec();
      for (int i = 0; i &lt; commands.length; ++i)
         if (commands[i].getBuilderName().equals(id))
            return;
      //add builder to project
      ICommand command = desc.newCommand();
      command.setBuilderName(id);
      ICommand[] nc = new ICommand[commands.length + 1];
      // Add it before other builders.
      System.arraycopy(commands, 0, nc, 1, commands.length);
      nc[0] = command;
      desc.setBuildSpec(nc);
      project.setDescription(desc, null);
   }
</pre>
Alternatively, you could edit the project description directly on disk
by modifying the <tt>.project</tt> file:
<pre>
   &lt;buildCommand&gt;
      &lt;name&gt;org.eclipse.escript.builder.Builder&lt;/name&gt; 
      &lt;arguments&gt; &lt;/arguments&gt;
   &lt;/buildCommand&gt;
</pre>
A builder is normally added to a project in the project creation wizard
but can be added later on.
