[I created a Jar file.](https://i.stack.imgur.com/SPbhy.png)

When I use it in my project it seems to be able to find the Package name just fine but I can't use the classes within.

[Package name, but no classes after.](https://i.stack.imgur.com/7MiN8.png)

Did I do something wrong when creating the Jar?
I ran "jar cvf Adapter.jar \*".

Any suggestions would be a great help!
