I have just installed 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.

I just installed Eclipse Photon. I migraded one project from Oxygen to it - everything is working fine.
The problem I noticed is that I cannot open the Eclipse Marketplace. Whenever I click on it, I get the loading circle for 1-2 seconds then nothing happens.
I also tried this on a completely new empty workspace (so no old .metadata) - same behavior.
I also restarted PC - didn't help.
Any ideas? Is it me only that has this problem or is it a bug due to the new version?
Thanks.
I managed to find the problem and fix it. I went to:
Help -> About Eclipse IDE -> clicked on "Installation Details" -> tab "Configuration" -> Clicked on "View Error Log"
The default browser opened and there I noticed the following stack trace:
!ENTRY org.eclipse.ui 4 0 2018-06-28 10:38:21.036
!MESSAGE Unhandled event loop exception
!STACK 0
org.eclipse.e4.core.di.InjectionException: java.lang.IllegalArgumentException: Illegal character in path at index 16: file:/C:/Eclipse Photon/eclipse/configuration/
at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:65)
It was the space character in the folder named by me: "Eclipse Photon". I renamed it to "EclipsePhoton" and the marketplace opened successfully.
Short answer: Make sure you do not have any spaces in the Eclipse installation file path.
I fixed the issue with the solution from this link: https://www.chrisguindon.com/post/marketplace-client-not-opening-in-photon/
Steps:
Go to Help > Install New Software
Paste the Marketplace Client update site url into the “Work with”
field: http://download.eclipse.org/mpc/photon
Select the “EPP Marketplace Client” checkbox
Follow the wizard and restart your Eclipse to finish the
installation.
Addition to actunderdc answer:
He is right. There is a bug if there is a space in the installation path. If you want to install in the Program Files folder, you can use the windows shortnames.
Find the shortname of the folder in cmd by using dir /X. For C:\Program Files it is something like PROGRAM~1.
When you got the shortname, you can add the folowing at the top of your eclipse.ini File in the same directory of the eclipse.exe
-launcher
C:\PROGRAM~1\eclipse\jee\photon
Make sure to adjust it to your installation path. After you have done this, marketplace can be opened. But when I open Help -> About -> Instalation Details -> Configuration it shows me two -launcher parameters with the long and the short name. I don't know, if it could cause sideeffects.
I opened a Bugreport at bugs.eclipse.org.
Had similar problem, this is what I did:
NOTE: If you have any other firewall software then make sure to allow eclipse though it & also check if your computer's time is proper(else leave this).
Open Eclipse >
Help >
Install New Software.. >
Enter link in work with " http://download.eclipse.org/mpc/photon/ " >
(after lodaing) select the EPP Marketplace Client and install it
I had error while installing it, I just allowed eclipse through firewall then marketplace client updated smoothly. Then I restarted eclipse and marketplace opened.
Hope this helps.
I had this problem on my Ubuntu 18.04 machine, none of the above helped.
After hours of searching, I found a working solution: enable theming under Window - Preferences - General - Appearance
I had this disabled, so Eclipse uses my GTK Theme (Arc dark) and looks better.
But enabling it makes Marketplace start again.
The stacktrace in the Eclipse error log (Window - Show View - Error Log) contained a hint that lead me to the theming option.
First when trying to use WindowBuilder (SWT) in Eclipse JEE 4.8 you must remove all spaces from your Eclipse folder name that contains all its files. This first step was discovered via link:
Eclipse Photon - Eclipse Marketplace not launching
Secondly, is this link tells the second half of the mystery. If you go to:
http://download.eclipse.org/windowbuilder/WB/integration/4.8/
you will see on the left hand side "show directory contents" which will have "repository.zip" file as last file of this expanded list. Download this (~39Mb). Note path to this file, then in eclipse click on "help" (last menu item), then click on "Install New Software...", then click "add", then click "archive" and go to path of saved "repository.zip" and select it. You will see square check box now indicates file to install.
I believe one must then click "continue" (check box already checked for WindowBuilder install item), then confirm when all files to be installed show are shown on screen, then finally click "finish". After the file is loaded in archive step I am not sure of the exact verbiage used for remaining steps but I believe what I have said is mostly accurate and after adding archive it will be self evident (piece of cake) what steps to follow. Finally to check if Window builder is installed go to (in top menu items) "file" then "new" then "other" and then finally scroll down list and WindowBuilder should be in this list, otherwise you landed a goose egg and something went wrong.
Change your folder name eclipse photon to eclipsephoton if any space in your folder name its not open Eclipse Marketplace
I had the same problem. I solved it by changing the name of the folder where eclipse was installed, the name i had used for the folder had a space and that was precisely preventing the use of the market place in eclipse, i removed the space and it worked normally.
For Ubuntu 20.04,
Just remove the spaces in your folder name of the eclipse folder and try closing and reopening the eclipse.It will works!!!
I had made an maven project and it worked fine.
Then I installed plugins
EclEmma Java Code Coverage,
PHP Development Tools (PDT),
Eclipse.orgSonarQube
Then I worked on some other project. When I again wanted to create an maven project,it threw the following error window which said
The selected wizard could not be started
reason
plug-in org.eclipse.m2e.core.ui was unable to load class
org.eclipse.m2e.core.ui.internal wizards.MavenProjectWizard
Removed SonarQube plugin .This solved the issue.
Now it works all fine.
But is there any other solution to this problem since I have to use sonar.
Click on eclipse help tab and open installation details search sonar and remove all related plugins.
That's not quite the right characterization of what it says on the page,Please check your .log file /path/workspace/.metadata/
Find the correct plugin which is causing this problem and update to compatible version of the plugin with eclipse version.
To find the hidden files in the workspace use Ctrl+H
I had the same problem, and I've tried so many solutions. But what I did to solve the problem, is that I just upgraded my Eclipse IDE (2019-06 to 2020-03) by following these steps (from https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F) :
You first need to add the new release's repository as follows:
1-1. Window > Preferences > Install/Update > Available Software Sites
1-2. Click 'Add'
1-3. Enter the URL https://download.eclipse.org/releases/2020-03/
1-4. Click 'Ok'
Help > Check for Updates
If updates are found, proceed through the install wizard and restart the IDE when
prompted. Otherwise, read carefully the error message to find out which component
is conflicting and establish your resolution strategy.
Note that the start splash screen may be cached and will not necessarily be
updated to the latest version after the IDE is restarted. Performing a full
relaunch should display the new version number.
I launched Eclipse earlier to jot down a snippet and was faced with the following as an error when I tried to run a fresh project:
An internal error occurred during: "Compute launch button tooltip".
That popup window shows as soon as I mouse-over the run icon in the top bar, or if I right click on the class in the explorer window and select any of the run/debug options.
After doing some research on the error, I see several people who posted similar messages but they all have been fresh installs of Eclipse. So note that this is not a fresh install, and that Eclipse was working fine earlier today. Also note that not only does my new project not run (with the normal main method), but projects I was running earlier have all stopped working with the same error.
Finally, also be aware that after seeing other people's suggestions on fixing this, one specifically said to select run configurations from the top of the page run menu. When I selected run configurations from this dropdown, I got the following message:
Exception occurred creating launch configuration tabs
Reason: Plug-in org.eclipse.jdt.debug.ui was unable to load class org.eclipse.jdt.internal.debug.ui.launcher.LocalJavaApplicationTabGroup
After that message, the run window opens but all of the tabs are missing. Like where you can set the display width and height, and the other tabs, they are all missing from the window now.
I was using Eclipse trouble free earlier today and I am sure no updates took place between when Eclipse was working and now. My question is of multiple parts: What is wrong in a nutshell? What could have caused this?
Got this from another site of some guy who got this same error after upgrading.
Worked for me as well.
Apparently putting the following line in your eclipse.ini helps:
-Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU
Try setting the launch properties in:
Window>Preferences>Run/Debug(Expand)>Launching(Click)
Under launch Operations menu set it to:
Always launch the previously launched application
Click:
Apply>Ok
I never found out what went wrong, but a reinstall of eclipse fixed it. All projects survived seemingly undamaged.
Thanks for the reply on the .ini but that did no good.
I had same error today - in an eclipse installation (Juno SR2 64bit) that has been running fine for months.
0: There were no changes on svn for my projects since yesterday (when it was running fine).
1: I restored the workspace from a 'Windows 7 -> Properties -> previous copy' backup. This failed because the directory structure of the '.metadata' contains folders with a deeper structure than is supported.
2: I restored the workspace from a overnight archive (gzipped so file depth is not an issue).
This had no effect.
3: I tried to restore the eclipse installation directory (which seems to be updated an awful lot) from a 'Windows 7 -> Properties -> previous copy' backup. Again this failed - because of folder-depth issues (Note: it is installed in the root directory of my disk - so there is actually no way to use a restore on this installation!)
4: Had to delete the .metadata from my workspace and reinstall eclipse (and all the additional plugins), and re-import my projects, and setup all the servers, and android, etc, which took many hours.
The moral of the story? Backup both your workspace AND the eclipse installation every night manually. Windows Restore will NOT save you. Backing up your workspace is NOT enough.
I had the same problem using eclipse mars. I cleared the folder .recommenders\index
And that solved my issue.
Hope it helps.
incase you are having the eclipse files which you have downloaded from the official site .Just extract those file in the same folder where your previous eclipse was installed and select replace all.
best solution
I also encountered this issue, the reason why this issue occurred on my project was due to I was missing the JRE System Library in the root folder of my project.
To solve this issue, make sure you have the libraries like JRE System Libraries on the root folder of your project.
I'm getting the error given below when I try to install the upgrade from Eclipse and it goes like half way and then throw the error.
An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Unable to write to repository: file:/C:/Program%20Files/eclipse/.
C:\Program Files\eclipse\plugins\org.jboss.netty_3.2.4.Final-201112281337.jar (Access is denied)
Kindly provide the solution.
Thanks
If you have problems using the location: http://dl-ssl.google.com/android/eclipse/,
try editing the location by replacing "http" with "https" or the other way round.
On Windows 7, the Program Files directory is protected so apps can't automatically write there. The simplest solution I've heard is just to install Eclipse into a user-writable location instead. For example, C:\Java\Eclipse
You should be able to just move your entire eclipse directory, there's no registry entries or anything else that ties Eclipse to the place where you extracted it.
[Edit]
Have you checked that the directory it is complaining about i actually writable? Other than that, I really don't have any ideas. I haven't worked on Windows in several years and never with Win7. My only other suggestion is to just download the latest Eclipse, install it to a new location (do NOT intall it over top of your existing Eclipse), and point it to your existing workspace.
I just solved this problem by unchecking Read only checkbox of the Program Files/eclipse folder on win7.
Apply to all files and folders.
I had also the ADT Bundle that had the HTTP as update url.
Changing it to HTTPS solved the problem for me.
None of the above worked for me.
Instead, I tried installing the plugins I needed via the Eclipse Market Place, and that worked without issue.
Click "Help" Menu.
Click "Eclipse Marketplace..." menu item.
Enter the name of the plugin you want.
Click "Install" when the plugin appears in the Marketplace List.
Restart Eclipse.
if you do not wish to change the eclipse directory, then start eclipse as administrator (right click run as administrator) and install the feature again. it worked for me.
I got this error on my ubuntu box until I ran eclipse as root and installed from there:
$ gksudo eclipse
Eclipse was trying to download the packages to /usr/lib/* where I don't have write permissions
Changing from https:// to http:// worked for me
Installig Eclispe ADT from market place solved this problem for me.
I solved the problem very easily.
Go to Control Panel -> Network and Sharing Center -> Windows Firewall -> Turn off Windows Firewall
And try to install again and see the magic :)
In my case I entered:
Error Log - found "An error occurred while collecting items to be installed" - right click and select "Open Log". From there I know what goues wrong(in my case PMD). I solve the problem in one project and all works ok.
If there are any proxy networks are configured remove them till plugins are installed
I'm running Eclipse Europa (3.3). I leave the "Build Automatically" setting, under the Project menu, on all the time. Once in awhile my code isn't compiling, and I puzzle over it and then pull down the Project menu ... lo and behold, it's not set anymore. What gives? Is this a bug, or is there something else I'm doing that could cause it?
Edit: I am running the regular Java developer installation, plus Subversive and its connectors, Jetty Launcher, and I believe no other plugins. Other people at my workplace have had the same problem.
Edit: I am still having this problem once in a blue moon, only now I'm using Eclipse Galileo (3.5) for Windows. I haven't had this problem in Galileo for OS X, neither in Cocoa nor Carbon, but I have not used that for as long.
With Eclipise Mars.1 (4.5.1), Oomph may be the culprit. Eclipse Oomph supports automatically disabling Build Automatically with entries in
On Windows
%USERPROFILE%\.eclipse\org.eclipse.oomph.setup\setups\user.setup
If you want to disable this Oomph behavior try deleting the following setting
"Eclipse->Navigate Menu-> Open Setup menu entry-> Open User menu entry", a Preference Task under "User Preferences -> org.eclipse.core.resources -> description.autobuilding"
I learned about this setting by posting to the Oomph Eclipse Community Forum on Feb 8th, 2016. I posted a question titled "Oomph Defect? Build Automatically Keeps Getting Disabled". Ed Marks replied the same day with details about Oomph's support for managing the Eclipse "Build Automatically" setting.

I don't have eclipse right here to test and make sure but here is an idea.
Is any of the project or even workspace file in SVN ? if they are and they were uploaded with auto build disabled that might explain it
You update and overwrite your settings. This doesn't become apparent until you restart eclipse. this would also explain why other people at your workplace experienc this. it would even explain why some don't : thay are the ones who are careful what they update and don't allow eclipse to overwrite their own settings plus the ones who actually prefer to have autobuild disabled :)
I had the same problem and when I looked at the Source tab under Java Build Path (under the menu Project > Properties ) there were some source directories that didn't exist anymore (marked with a red X). After I deleted them, compilation worked fine and all new .class files are under the bin folder.
Strange. Is there perhaps a plugin installed that turns this off without your knowledge?
Maybe there is some conflicting shortcut. For example, some duplicated shortcut may be toggling it.
I am running 3.4 and I also have this mysterious behavior. I had it in 3.3 as well. I use CVS not SVN. Does not seem to follow a pattern just once in a while it gets switched off and then weird confusing stuff happens until I remember to check it and switch it back on. I am almost to the point where I want to write a plugin to always turn it on when eclipse loads.
When installing Google Plugin for Eclipse, 'Google App Engine for Android' is also installed.
For me, I uninstalled 'Google App Engine for Android', which I didn't need, and solved this problem.
