I installed the 8.5 all-in-one, added mylyn (seemed to go OK) and then tried to add GWT. The GWT install failed with missing pacages initially. Pulse updated their stuff and on retry it failed again with “stallled” messages.

I restarted MyEclipse and got an error popup on the (initial) Config Center page:

An internal error occurred during: “Update Installed JREs”.
java.lang.NullPointerException

I restarted again and there was no error. I saw no error information about any of this in the log (should be).

I tried the GWT install again and again it “stalled”.
When I tried to swith back to the workbench, the current editor window which was showing pom.xml put up an error:

Problems occurred restoring perspective.
  Could not find view: com.genuitec.eclipse.ast.deploy.core.serverview

In the workbench view, pom.xml editor showed an error:

Could not open the editor: No editor descriptor for id org.eclipse.wst.xml.ui.internal.tabletree.XMLMultiPageEditorPart

I closed that file and restarted MyEclipse. When I reopened pom.xml it seemed OK.
However, when I right-moused on it in the package explorer I did not see the Maven4MyEclipse option which I think used to be there.

I tried opening a clean workspace. The upper left window only had Project explorer rather than Package Exploerer. When I added Package Explorer it showed only four specific choices rather than the 10 or so I used to see. Many standard ones, such as web projects were not in any list.

Can you tell me what is going on here? Is all this caused by Mylyn or the configuration center?

Frank,

How did you add mylyn and GWT? Also in what sequence did you add the plugins? Can you mention the steps in detail, this will help me replicate this issue at my end. Also can you include screenshot which will give me a visual? Please use either the [Preview] / [post reply]/ [pm] button to send out the screenshots.

I opened the Configuration Center, Dashboard tab, selected Mylyn from the Quick-Add list (no related tools) and pushed the button to process it.
Seemed to go OK.

For GWT I selected Software tab, typed GWT in the Browse Software box and it showed “Google Plugin for Eclipse”.
I double clicked it and it added it to the pending list.
I pushed the button to process it.

The first post gives the details after that.

It looked like many of the product features had disappeared from MyEclipse so I decided this install was corrupted.
I uninstalled and reinstalled, set up my proxy, and then installed GWT.
It finally installed OK (no stalling).

I did NOT try to install Mylyn this time.
I suspect that Mylyn is the source of the problems.
Perhaps it has problems whenever any other product has any kind of install issue.

So far I can create projects with maven and all the correct MyEclipse functionality is present.

Frank,

Thank you for the details. Good to hear you are all set. I have already filed a PR for the dev team to investigate the mylyn issue. I will let you know as soon as I hear back from them.

Best.
