问题
I have recently been setting up SVN in Eclipse using the Subversive plugin (I am still a bit lost, but that's another issue).
I have been using this guide (http://soledadpenades.com/2008/12/10/add-svn-support-to-your-eclipse-installation/) and finally got it working! The only problem now is, I can't seem to find the Package Explorer, which is the only explorer I could ever seem to get working how I wanted it to (grouping projects into working sets).
Normally, you get it from going to Window → Show View → Other, and then select it from the list. The only thing is, it's not IN the list of views... leaving me rather confused.
Just to be clear, I was using the package explorer before with no problems. I am running the latest version of everything as I did the auto update.
Any suggestions as to what is wrong here?
回答1:
I'm guessing you've made it a fast view or minimised it to it. You could try holding down Ctrl + F7 to see a list of all views, then up/down arrow to the View. If Package Explorer is in the list it has been minimised or something.
If you select it and still can't see it, try Window → Reset Perspective... to restore all views to their defaults.
回答2:
Alt+Shift+Q worked for me when I was in debug mode.
回答3:
Weirdly enough, although reset perspective didn't work, menu Window → New window worked! It opened a new window with the perspectives reset.
回答4:
For me I needed to do two things:
- Reinstall the "Eclipse Java development tools" via Help → Install Software → Programming Languages
- Delete and recreate the .metadata Eclipse Workspace settings.
Honestly, deleting the .metadata directory is probably sufficient - try that first.
回答5:
At the top right corner, there is a button called Open Perspective. Click on it, and then Java Default. Everything will come back to normal.
回答6:
Are you sure you are in the Java perspective?
As views are related to perspectives this could be the problem. The current perspective can be found in the upper right corner.
回答7:
You may be missing the JDT plugin containing the Package Explorer.
回答8:
I think you were actually still in the Debug perspective, since that was what did it for me. As someone mentioned above, I had to go to the top right and hit "Java perspective" to get back to my normal views.
回答9:
Three answerers were helpful, however the only cure was to reinstall Eclipse and install the plugins again. Weird problem, and the exact cause not found. I may have deleted some files somehow, but a reinstall solved it.
回答10:
On the right top you can select Java or JRE or whatever. That button might got changed. So click the neighbor buttons such as Java or something.
回答11:
Go to Window -> perspective -> Open Perspective -> Java. Now all the packages in Java will be displayed in the package explorer.
