Using the Ant view
  Eclipse provides a standard view, the Ant view, that lets you
  work with your Ant buildfiles. This view is tree-structured, showing Ant buildfiles as top-level entries and targets
  & internal targets as children. The main advantage of this view is that you can work with all of your Ant
  buildfiles in one place, as opposed to hunting them down in one of the navigation views.
  
    - Open the Ant view from the workbench menu by selecting
    Window > Show View > Ant.
- By default, the Ant view is empty. There are three ways to add Ant buildfiles to this view:
      
        - Click Add Buildfile [ ]. This brings up a dialog in which you explicitly select those Ant buildfiles you want to
        add ]. This brings up a dialog in which you explicitly select those Ant buildfiles you want to
        add
- Click Add Buildfiles with Search [ ]. This brings up a search dialog in which you can specify a filename
        pattern for your Ant buildfiles and search within the entire workspace or a specified working set. ]. This brings up a search dialog in which you can specify a filename
        pattern for your Ant buildfiles and search within the entire workspace or a specified working set.
 
- Drag and drop buildfiles from other views to the Ant
        view.
 
 Once added to the Ant view, Ant buildfile entries remain in the view across workbench invocations until
        explicitly removed or the associated project is closed.
 
- Click Add Buildfiles with Search. Suppose you only remember that the buildfile you want to
    work with starts with H. EnterH*.xmlfor the buildfile name. Make sure Workspace
    is selected for the scope, then click Search. TheHelloWorld.xmlfile is found and placed in
    the Ant view.
- Expand the top-level entry to see the default target Hello, and the internal targetWorld.
- Select the Worldinternal target and click Run the Selected Target [ ]. Notice that just the ]. Notice that just theWorldtarget gets executed.
- Select the top-level HelloWorldbuildfile and click Run the Default Target of the Selected
    Buildfile [ ]. Notice that
    just the default target, ]. Notice that
    just the default target,Hello, gets executed.
- To edit your buildfile, bring up the context menu on the HelloWorldfile and select Open With
    > Ant Editor.
- To edit the default launch configuration, select Run As > Ant Build... from the context
    menu.
- The Run Ant launch configuration dialog appears. Here you can modify the way in which the buildfile is run from
    the Ant view.
- Select the HelloWorldfile, then click the Remove button. The buildfile is removed from the
    view.
 Note: This does not delete the file from the workspace.
