Eclipse TFS-源代码管理资源管理器错误

Question

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".

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.

Answer 1

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.

Answer 2

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.
