If you have some version of MyEclipse (Enterprise Workbench 6.6.0) which has no option to run a build file with ANT and you are confused on how to run the build in the eclipse, please follow the following steps:
- Go to the project
- Select build_XXX.xml
- Go to “Run As” icon
and click “Open External Tools Dialog…” - A new pop-up window for External Tools will appear with an option “Ant Build”
- Right click on “Ant Build” and click on option “New”

- A new ANT build task will be created and will look like the following

- Go to “Properties” tab and deselect option “Use global properties as specified in the Ant runtime preferences”

- Create a new file “[SomeName].properties” and write the required build properties into it.
- Click on “Add External…” and select the file created in step 8.
- The pop-up window will look like the following.

- Click on APPLY
- Click on RUN
- Check Console for any errors or Success message
