What does this mean if the eclipse perspective is shown in angle brackets?

Question

I wrote a new perspective for our Eclipse RCP Project, which worked great. But due to the wrong configuration, I had to go back to an earlier version of the code in which this perspective did not exist.

The strange thing is that after returning to the perspective dialog box that opens, the perspective is displayed. The only difference is that it now appears in angle brackets and appears twice.

So the entries in the open perspective Dialog look like that: --- a valid perspective another valid perspective <perspective that shouldn't be here> <perspective that shouldn't be here> yet another valid perspective --- 

What do angle brackets mean?

And how can I get rid of these records?

Thank you so much!

Answer 1

You can remove the perspective by choosing Window> Preferences, then choose General> Perspectives.

Highlight a “bad” perspective (one that has angle brackets) and click Delete.

Left forever :-)

Answer 2

Try deleting the full workspace at runtime!

Answer 3

Just a wild hunch, did you try the -clean while running eclipse? Locked entries in the workspace can lead to sporadic behavior.

Answer 4

I think this means that the perspective must be “restored” in some way, so the file is duplicated and renamed.

I had the same <> around my high point of view after I was unable to open my workspace due to errors in the damaged workspace. I downloaded a new copy of the eclipse and pointed it to the old workspace, but an error window appeared explaining that he could not find any views for plugins that were not installed, and then I used the perspective without these views. The file must be modified since Vista does not include them even after reinstalling the plugins and selecting "Reset Vista", etc.
