[1.7.10] Can't reload changed classes in IntelliJ

[whizvox]

First off, I'm using the recommended version of Forge for 1.7.10, 10.13.2.1291. Whenever I try to perform the "Reload changed classes" function in IntelliJ IDEA, I get loads of errors.

What can I do to fix this?

But when you launch normally it works?

 

Yeah, it works just fine.

I copied the contents of the Forge 1.7.10-10.13.2.1291 source download into a separate directory, changed a few things in the build.gradle to suit my mod, setup the IntelliJ workspace via command prompt (gradlew idea), opened the generated workspace in IntelliJ IDEA 14.1, setup the decomp workspace (gradlew setupDecompWorkspace), generated IntelliJ run configurations (gradlew genIntelliJRuns), and, upon the prompt, reloaded the workspace.
