Cannot "Install New Software" in Eclipse 3.5_问答_开发者

I have just installed开发者_C百科 Eclipse 3.5 for Java EE developers ("Galileo").

I need to add an extra plugin, but when I select the "Install New Software ..." menu item, nothing happens. Literally nothing - no dialog opens, no error message is displayed. If I have the Debug window open, no message are displayed.

If I go to Preferences -> Install/Update -> Available Software Sites, that dialog opens OK, I can manage the list of update sites, and test the connections, and they all appear OK. But I cannot get to use them to actually install anything.

Is it just broken, or could there be something more subtle wrong?

Thanks.

Start by checking you error log under Window -> Show View -> Error Log. See if you're getting any exception while trying to install new software.

You can also install by downloading the plugin and unzipping it in the dropins folder.

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.

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...

GDK_NATIVE_WINDOWS=true also solved the non-clickable button problem for me running gnome 2.28.1 with Ubuntu Karmic (9.10) x64 with kernel 2.6.31-14-generic

To resolve this problem, I did the following:

Placed my copy of Eclipse in the trash
Emptied my trash
Rebooted my computer
Downloaded the latest version of Eclipse (which was Indigo at the time of writing)
Placed the .zip file in my applications folder
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....

I suggest to use Eclipse Indigo (Eclipse 3.7) which contains EGit already.

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 had the same problem in windows... and spent couple of hours to "somehow" install the new softwares.

Anyway I will explain you how I managed to install it after trying many options..

Start a fresh copy of eclipse
First tick two check boxes(Show only latest version & Contact all update sites). Make sure the check box of group items is untick.
Try to add software... If not showing the list of plugins/Next buttons.
Delete the copy of eclipse.
Start a fresh copy of eclipse
Tick only the check box for Contact all update sites.
Now try to add plugins. It worked for me...

Even if it sounds crap... it worked for me..

If none of the solutions above work for you, simply change the workspace to another location. If the list of items appears properly then there's probably something screwed up in the workspace and not Eclipse. Hope this helps.

I actually just had a similar problem and wanted to offer the solution that worked for me. This was not a permissions thing. To solve that I always install eclipse as my user in my local directory (e.g. /home/[user]/local/eclipse-3.7.2) and then you never have permission issues.

Setup: Go to Help -> Install New software -> Available Software Sites (to add new site)

Symptom: Try to add a new site. After hitting enter or clicking finish the site shows up in the list of available sites. Click Okay to go back to the install new software and the site is not available in the drop down. Go back to Available sites and the site is gone.

Fix: After adding the site click on the reload button while the new site is highlighted (before clicking Ok to go back to the "Install new software screen"

This was occurring on Indigo SR2 (and has been happening for a while). I am running this on Linux Gtk -- but I don't see why this would be related.

Hope this helps!

Delete your ~/.eclipse folder and restart eclipse. This is the only thing that worked for me.

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".

just press enter after entering URL in "Install new software" window

I faced similar issue. To troubleshoot this issue follow these steps:

Go to windows -> show view -> error.
Check the error logs. In my case error was java.lang.IllegalStateException: Registry Directory not available. at org.eclipse.equinox.internal.p2.engine.SimpleProfileRegistry.restore
I checked my config.ini which is under eclipse -> configuration folder.
I found eclipse.p2.data.area has incorrect path set.
I set the correct path for above key and restarted eclipse. It started working. Hope it helps

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

Window (Eclipse Menu) -> Show View -> Error Log
if Error Log is not there, then: Window (Menu) -> Show View -> Other -> General -> Error Log
Once the Error log is shown, Go to Help (Eclipse Menu) -> Install New Software
Check the Error log, most probable you will see an exception there.
Check the exception, most probable it's caused by java.lang.IllegalStateException
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.
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.

I`m wondering if this help you.

Let me know if you have any queries.
