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’s build specification as follows:

   private void addBuilder(IProject project, String id) {
      IProjectDescription desc = project.getDescription();
      ICommand[] commands = desc.getBuildSpec();
      for (int i = 0; i < 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);
   }

Alternatively, you could edit the project description directly on disk by modifying the .project file:

   <buildCommand>
      <name>org.eclipse.escript.builder.Builder</name> 
      <arguments> </arguments>
   </buildCommand>

A builder is normally added to a project in the project creation wizard but can be added later on.
