Eclipse TFS - Source Control Explorer Error

I am using Eclipse (version Juno) with the TFS Plugin. When I click Source Code Explorer I get this error message:

Plug-in "com.microsoft.tfs.client.common.ui.vcexplorer" was unable to instantiate class "com.microsoft.tfs.client.common.ui.vcexplorer.versioncontrol.VersionControlEditor".

enter image description here

I saw this Eclipse plug-in development Unable to instantiate class due to java.lang.NoClassDefFoundError: but am not sure if it is the fix for this TFS plugin or what it really means:

put the project of the missing file as dependency in the plugin configuration file too.

I hope this can help somebody that researches this error. I was able to fix the problem on a virtual machine (Windows Server 2012 R2) running on a Windows 7 desktop with Eclipse Mars 4.5.0 and TFS plugin 14.0.1.

Plug-in "com.microsoft.tfs.client.common.ui.vcexplorer" was unable to instantiate class "com.microsoft.tfs.client.common.ui.vcexplorer.versioncontrol.VersionControlEditor".

I installed Eclipse and the TFS plug-in on both the desktop Win 7 and the virtual machine. It worked perfect on Win 7 but on the virtual machine running Windows Server the error came up.

My first step to solve this was by following moerketh advice and moved that specific file from Win 7 to Server 2012.

...plugins\com.microsoft.tfs.client.common.ui.vcexplorer_10.1.0.201101271439\com\microsoft\tfs\client\common\ui\vcexplorer\versioncontrol\ VersionControlEditor$VersionControlEditorRepositoryUpdatedListener.class

It did remove the error but did not show the folders in the server. In other words, I couldn't see the folders I am trying to map to.

Next, I decided to copy all files in the folder as shown below and paste it to the same folder in the virtual machine.

...plugins\com.microsoft.tfs.client.common.ui.vcexplorer_10.1.0.201101271439\com\microsoft\tfs\client\common\ui\vcexplorer\versioncontrol\ VersionControlEditor$VersionControlEditorRepositoryUpdatedListener.class

Restarted Eclipse, and then the TFS folders showed.

I've seen this exact error before on my box. In my case this file had gone missing due to its long path and filename:

"...plugins\com.microsoft.tfs.client.common.ui.vcexplorer_10.1.0.201101271439\com\microsoft\tfs\client\common\ui\vcexplorer\versioncontrol\ VersionControlEditor$VersionControlEditorRepositoryUpdatedListener.class"

You can see how this can get somewhat long. I'd suggest checking if you have all the files perhaps comparing it with an installation on a shorter path. Hope this helps.
