The accepted answer explains in general terms how to create a WAR file in Maven.

However you are asking how to create a WAR file for "multiple or diff[erent] application code". The answer depends on what you mean.

• If you mean a single webapp that has multiple components and / or dependencies, then the accepted answer should work.

• If you mean a multiple webapps ... there is a problem. A WAR contains a single webapp. There is only one WEB-INFO tree and only one web.xml file in a WAR file. So your options are:

  • Create and deploy multiple WAR files.
  • Try to integrate the separate webapps into a single webapp. This could be as simple as rewriting the web.xml files and combining the WEB-INFO trees. Or it could be more complicated. Then create the WAR for the combined webapp.
  • If your web container supports this, you could create and deploy an EAR file containing multiple webapps; see .war vs .ear file
