ClassNotFoundException: com.intellij.mock.MockProjectEx

[breandan]

Not sure if related to GrammarKit or the gradle-grammar-kit-plugin. Updating to ~2019.1~ 2018.3.1 caused the following error on this project (works fine on 2018.3):

@gregsh could you please assist?

[gregsh]

If it is https://github.com/JetBrains/Grammar-Kit/issues/213 I'd suggest to form a proper class path manually than to depend on MANIFEST.MF.

[Undin]

Looks like the reason of this exception is this commit Now the plugin tries to find MockProjectEx only in several jars and it works with IDEA distribution (where MockProjectEx is in idea.jar) but doesn't work with CLion because MockProjectEx is in testFramework.jar that are not in classpath I've made PR that fixes it #18

[breandan]

@hurricup Are you planning to update the Gradle Plugin Repository to include this fix?
