@ujjwalarora - Please use both JIRA issue numbers AND a descriptive phrase in your pull requests AND commit comments, as described in https://wiki.openmrs.org/display/docs/Using+Git under step 3 in section "Work on your task".

The logic behind my solution is that whenever dwr-modules.xml file is not found, a script creates it using DOM before its used further in WebModuleUtil.java, and hence its very well recognized by the XML parser and new module information is written into it.

Steps to Test :

1.) Delete the dwr-modules.xml from /webapps/openmrs/WEB-INF/dwr-modules.xml.
2.) Try to add/delete a module
3.) New dwr-modules.xml file would be created with the module info

@ujjwalarora can you add a unit test for this?
Secondly, can you always run "mvn clean install" before you commit to ensure that your changes are formatted according to our conventions?

@dkayiwa Done. Added 2 unit tests such that they PASS in the edited file and FAIL in the previous configurations.
Yes, done 'mvn clean install'
