How do I get rid of "Current text selection cannot be opened in an editor" in Eclipse?
eclipse-jdt
Solution
[UPDATE] This seems to be a bug somewhere in the depths of m2e and JDT. Usually, it appears when you have several projects (Maven multi module / reactor build) and the modules `MA`, `MB` and `MC` depend on each other:
`MC` depends on `MB` depends on an inner parameterized type `X.Y<T>` of `MA`.
and you have closed the module `MB`. On the classpath of `MC`, this will look like so:
MB.jar
MA
That is `MB` exists as a JAR on the classpath while `MA` is imported as an Eclipse project from the workspace.
In this situation, Eclipse gets confused when reading `.class` files in `MB.jar` which need inner parameterized types from `MA`. My guess is that it needs the type from `MB.jar`, parses it which tells it of the dependency to the type in `MA` which it then tries to parse only to find that the type parameter for `T` can't be resolved since parsing of `MB` isn't finished, yet.
There are three fixes:
- Close `MA`. That will import everything as a JAR.
- Open the project `MB`.
- Make the inner type a toplevel type
[OLD]
If this happens, try these steps in order of increasing despair:
- Close the editor and open it again.
- Clean the project
- Close the project and open it again.
- Restart Eclipse
If all that fails:
- Export your preferences
- Exit Eclipse
- Delete (or rename) the folder `.metadata` in your workspace. It's an invisible folder on some OSs but it's there.
- Start Eclipse again
- Import your preferences
- Import all projects again. For this, select the workspace. Eclipse will then list all projects in the dialog and you can select all of them at once.

Problem
Sometimes, I get this message in the status bar when I press F3 on a Type in a Java editor: Current text selection cannot be opened in an editor When I copy the selection into the clipboard and use Ctrl+Shift+T to open the "Open Type" dialog, I can paste the value and it will display the type and I can open it. The type is on the class path (no compile errors). In other Java editors in the same project, F3 / Ctrl-Click works. In the "broken" editor, it only works on internal fields and methods. For internal fields, it only works in the place where the field is defined. All places where a field is used are dead. "Mark Occurrences" works, though. How do I get rid of it? So far, I tried: - Close and open the editor - Clean the project - Clean all projects - "Update Project..." in the Maven context menu - Restart Eclipse - Restart Eclipse with -clean This happens on Eclipse 3.7.2 with m2e 1.3.1 installed.
