Answer 1

I had the same problem, took a look at the error log and changed the launcher from "/usr/bin/eclipse" to "sudo /usr/bin/eclipse", it was a permissions thing...

Answer 2

Something you can try:

• Delete (rename/move) your workspace and try again. Be sure to backup all your projects and settings.
• Download the plugin "manually" and use Eclipse>Window>Preferences>Install/Update>Available Software Sites to add it locally.
• Download the plugin "manually" and use Eclipse>Window>Help>Software Updates>Available Software>Add site>Archive, find the directory on your HDD and add it.

I have faced the same issue. To solve the problem, follow the following steps:

1. Window (Eclipse Menu) -> Show View -> Error Log
2. if Error Log is not there, then: Window (Menu) -> Show View -> Other -> General -> Error Log
3. Once the Error log is shown, Go to Help (Eclipse Menu) -> Install New Software
4. Check the Error log, most probable you will see an exception there.
5. Check the exception, most probable it's caused by java.lang.IllegalStateException
6. Check the path mentioned in the exception, if you see ".Lock" in the path, close the eclipse then go to the path in windows machine and delete that folder.
7. now go to the eclipse "exe" file that you're using and open it as an administrator, then try, most probably this will solve the issue.

Answer 4

I ran into the same problem. There seems to be a bug related to the finish button (I am assuming this is the same problem you are experiencing). The way I got around it is by clicking on the finish button (or next, or whichever button is not working for you) and press the 'Enter' key. It's annoying. Seems to be an issue with how Eclipse is integrating with GTK.

Answer 5

I had the exact the same problem. What I found out is that I installed the eclipse as root user. Therefore, I need to be a root user in order to launch "Install New Software".

Answer 6

To resolve this problem, I did the following:

1. Placed my copy of Eclipse in the trash
2. Emptied my trash
3. Rebooted my computer
4. Downloaded the latest version of Eclipse (which was Indigo at the time of writing)
5. Placed the .zip file in my applications folder
6. Double-clicked on the compressed zip to open it (I'm using Mac OS X.6)

The problem disappeared. I am now able to do Help/Install new software....
