I ran into this problem in my filename.xhtml using Eclipse Mars .

I fixed this:

1. Right-click on the damage file.

2. Select Open With → Editor by default.

After that, everything returned to how it was.

Answer 2

Your file association settings may be confused.

• Open a window → Settings → General → Editors → File associations.
• Check if the file type (* .java) is in the list.
  • If it is listed, make sure that the correct editor is selected by default.
  • If it is not in the list, add it and edit it using the correct editor.

Had the same problem with .HTML files.

Although my file associations were set correctly, the following solution that solved the problem:

• Right click on your project file -> Open with
• Check out another internal editor -> select the editor of your choice (my case = HTML editor)
• At the bottom, check the box "Use this editor for all ... files" + "Use it for everyone .."

Answer 4

Try:

• right click -> copy class
• go to the desktop and paste
• return to eclipse right click delete class
• copy and paste from the desktop

This works for me.

Answer 5

I had the same error and fixed it by changing the workspace folder in Aptana: "General → Startup and Shutdown → Workspaces". I deleted the existing one and added the following: "C: \ Aptana_Studio \ workplace" (instead of the workspace folder in my user profile).

JFYI: I found that this error occurred after I installed Eclipse for Java.

Answer 6

I had the same error when I started my eclipse.
I fixed it by deleting the .project file and adding the project to my workspace again.
