cannot create class "org.jetbrains.plugins.innerbuilder.InnerBuilderAction" [Plugin: InnerBuilder]

[qwelyt]

I get this error when I install the plugin.
Using IntellJ IDEA 14.1.2

I just installed the plugin, restarted IntelliJ, and it gave me the error.

How did you install it? Only install from Intellij's repository.

Hi. I have the same issue, screenshot from IDEA error details dialog attached. I suppose you have compiled plugin with Java 8 version, but we start Intellij IDEA with Java 7. Possible solution is to compile application with Java 1.7 or set targetCompatibility in gradle.build file (http://gradle.org/docs/current/dsl/org.gradle.api.tasks.compile.JavaCompile.html)

Fixed.
