Running External Tools
  The Workbench provides a mechanism for running tools that are not part of it. To configure an external tool:
  
    - Click  Run > External Tools > External
    Tools.... Run > External Tools > External
    Tools....
- Select the Program configuration
- Click the New button.
- Enter a name for your external tool (for example, My External Tool).
- Click the Browse File System button.
- Find the tool you want to run (for example, on Windows it is usually a file with the extension .exe or
    .bat).
- (Optional) In the Arguments field enter the necessary arguments for the tool.
- (Optional)In the Working directory field enter the working directory for the tool.
- Click Run.
These steps create a persisted launch configuration. The newly created configuration will appear in the launch
  history under Run > External Tools and will be available in the launch configuration dialog which is opened
  by clicking  Run > External Tools > External
  Tools....
 Run > External Tools > External
  Tools....
  It is also possible to set up and run an external tool to build a project.
  
    - Select the desired project.
- From its pop-up menu choose Properties.
- Click Builders from the list, and configure the tool as described above.
