CLASSPATH and Manifest file

Question

I do not understand the rules of setting a classpath within a manifest of a jar file.

I seem to get it to work and then not get it to work. From the documentation I have read so far I only know you can't use wildcards

Could someone please post a link on how to set the classpath within a jar file

Solution

Normally you generate manifest files by using build tools like Maven or Gradle.

If you want to do it manually you have to use following form:

Class-Path: jar1-name jar2-name directory-name/jar3-name
