java.lang.NoClassDefFoundError in Intellij 14 with ANTLR4 plugin

I've installed the ANTLR4 plugin for Intellij, but cannot work with grammar files.

Upon the IDE start I immediately get:

NoClassDefFoundError:
org.antlr.intellij.plugin.ANTLRv4PluginController@109bb62:
org/antlr/v4/runtime/tree/gui/TreeViewer

Then, when I double click on a grammar file I get:

NoClassDefFoundError: org/antlr/v4/runtime/Lexer

Seems like IDE does not know where to pick the ANTLR jar file.

My project does have a dependency on antlr-4.5-complete.jar.

Are there some addition configuration steps I need to perform in order to let the IDE know where to look for the proper jar?

Hooray! Ok, so then the answer to this question is to ask intellij to install the plug-in. Or you can download intellij-plugin-v4.zip, but don't unzip it.
