NoClassDefFoundError on "Reload Gradle UI" click

[sbszcz]

Hello,

i am using IntelliJ Idea v126.330 and configured the gradle location in the settings menu.

Clicking the "Reload Gradle UI" button throws the following exception:

NoClassDefFoundError: Error during dispatching of java.awt.event.MouseEvent[MOUSE_RELEASED,(226,308),absolute(218,300),button=1,modifiers=Button1,clickCount=1] on frame0: org/jetbrains/plugins/gradle/util/GradleLibraryManager

Plugin version is 1.7

The same exeception class, but with a different message in Idea 12.1 EAP (128.18) on an IDE start up.

This is still happening on the new version of idea released today.

IDEa 12.1 JDK 1.7 same stack trace as above

[swavkulinski]

Same on 12.1 IC JDK 1.6

[ctapobep]

2 months without resolution. Plugin is not working at all.

[barrybecker4]

I get the same error.

[danielesegato]

Same here

Android Studio

[kaamoss]

I'm also affected by this!

[hubertsa]

Same here, IDEA 12.1.4. Still no solution ?

[IgorGanapolsky]

Yup, same issue! Android Studio 0.2.11

[nelwa]

Same issue here...please help.

[waynerasmuss]

To work around this I just created an external tool in Idea to launch the Gradle gui. It's just about as good. I created external tools to do a lot of things actually. Build All etc. It would be nice to have the plugin fixed, but the external tools approach gives just about the same functionality

[laminko]

same issue, too.

[mlgiter]

The very same story. Gradle GUI plugin crashes at ide startup

[hubertsa]

I am out of the office until 21/04/2015.
