Use this when : a dependency is not available on a public Maven repository and you need your project portable (ex: unreachable repository), or it’s not a maven dependency at all (ex: proprietary IBM jars)
Warning: It is not recommended that you store your JARs in CVS. See the folowing page:
https://maven.apache.org/guides/introduction/introduction-to-repositories.html
Demo
You’ll need Eclipse, Maven, Java.
Two jars are embedded in the project. One in a system path way like Ant, and the other like an embedded Maven repo. The second solution is the better, because it looks like a maven repo and integrate easly in Maven lifecycle and plugins (versus systemPath where it’s not easy to embedded the jar in the final app, like a war).
No compile error here: you can use these jars.
