Hello,

After upgrading from MyEclipse 10.5 to 10.7 (10.7-20121026 to be exact), I’ve been experiencing some errors. My platform is JRE 1.6 on Windows 7 64-bit.

For unknown reasons, my workspace is becoming corrupted in some way resulting in errors from deploying web applications I have in my workspace. I have several web applications in my workspace but I have experienced this issue with only 1 project in the workspace.

Errors occur at two places:
1) Anytime a web project is built, I get errors from the com.genuitic.ast.deploy.core plugin. I am assuming this occurs because MyEclipse is attempting to deploy files whenever the project is built.
2) Whenever I try to open the “Deploy MyEclipse J2EE Project to Server” dialog I get an error in the org.eclipse.ui plugin whose underlying cause (based on stacktrace) is also a NPE in com.genuitec.eclipse.ast.deploy.core.

I have found the following workaround to the issue:
1) Exit MyEclipse
2) Delete the directory $WORKSPACE_DIR\metadata\.plugins\org.eclipse.core.resources
3) Start MyEclipse back up
4) Bring my projects back using the “Import existing projects” feature[/list]

Once I do this, things will be ok for some time but the errors will inevitably return again. I have not been able to determine exactly what it is that causes the errors to start happening again.

I would like to note that I attempted to start over with a fresh workspace entirely. I did not “import existing projects” in the fresh workspace, but I bring my projects in as new projects from our SVN repository. This did not solve the problem.

It’s also relevant that this same workspace was in use with 10.5 and I never had any problems. I recently upgraded to 10.7 and that’s when the problems started.

Here are the detailed error logs:

Also, whenever I try to open the J2EE server deployment dialog , the dialog fails to open and the following exception appears in the error log:

jlaudadio,

Sorry that you are seeing this issue. The issue might be due to some corruption in your deployments.

Can you please try these steps to fix it :

1. Shut down the workspace.

2. Delete the file com.genuitec.eclipse.ast.deploy.core.prefs which is located at <workspace dir>/.metadata/.plugins/org.eclipse.core.runtime/.settings/com.genuitec.eclipse.ast.deploy.core.prefs

3. Start the IDE.

Let us know how it works for you.

[jlaudadio]

Doing that did fix the problem. I will let you know if the errors return again.

jlaudadio,

Glad that you got it working.
Let us know if you see any issues.

[jlaudadio]

My workspace has become corrupted again. Your workaround does resolve the problem, but what can I do to try track down what keeps corrupting the workspace in the first place?

jlaudadio,

Sorry that you are seeing issues.
I have escalated it to a dev team member. They will get back to you.
