Error invalid LOC header (bad signature) | jar binary

The Jar files custom or out of the box is important to be checked in as binary file into the version control system. If you check them into CVS or SVN as text files. It usually not a problem if your build process is on windows as windows is more forgiving about the file types checked in. If you use Linux or any UNIX based CVS\SVN servers. The build would through up with the error as below. The fix is either to override and check in the jar files as binary files or run some commands to change the type of the JAR files in CVS.
