Hi guys, first time including local compiled JARs in my `build.gradle` with `dependencies {...compile files('/path/to/jar/the.jar')}` and the gradle build was successful but when i'm trying to add a dependency to the project I want to use it in, i'm getting the following from IDEA;
```IDEA cannot determine what kind of files the chosen items contains.
Choose the appropriate categories from the list.
Classes
External Annotations
Jar Directory
JavaDocs
Native Library Location
Sorce Archive Directory
Sources```
what do I need to choose to make the classes available? or does this message mean that i've done something wrong in my build?
