"Cannot resolve symbol" for all classes from external library in Intellij

I have an Intellij project that uses Gradle. I've added an external dependency in the form of a JAR file in the libs folder, and added it to build.gradle using this:

compile fileTree(dir: 'libs', include: '*.jar')

Intellij recognizes it as a dependency, since it allows me to browse the file and view its contents, plus it suggests the packages I can import.

However, I can't use any of the classes contained. Intellij says Cannot resolve symbol '[classname]'. This occurs in both the library itself and my project files.

Other Gradle dependencies work fine, like those in the form compile "some.group:artifact:version".

I've tried all of the fixes I've found online for this, including:

How can I use this local JAR file as a dependency?

It looks like the jar you've attached contains *.java files instead of the compiled *.class files.

Library dependencies will work only for the jars with the .class files. Find a library jar instead of the source jar for this dependency and place it to the libs directory, reimport the project.
