Eclipse keeps showing the splash screen and then closing immediately after...I just downloaded it so I haven't had the opportunity to make a work space. I've tried uninstalling and reinstalling, the file has already been unzipped at this point I have no idea as to what I should do about this.
Make sure that you have installed Java JDK properly
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Whenever it (Eclipse) encounters a problem that does not warrant launching a dialog, Eclipse saves a report in the workspace log file. The log file can be looked at in four alternative ways.
Locate the file yourself, see workspace/.metadata/.log.
Start Eclipse using -consoleLog. This will print the messages
that normally go to the .log file in the enclosing shell/command window. When the Java VM suffers a hard crash, it produces a separate logging file named something like hs_err_pidXXXXX.log. These files are also helpful for diagnosing
problems.
(Other two might not be useful in your case)
Window > Show View > PDE Runtime > Error Log. This gives you a view
with the contents of the .log file.
Help > About Eclipse Platform > Configuration Details. This
prints out a great number of details about the environment and
also concatenates the .log file. Great for including in a bug
report.

Make sure that Java installed properly..
Uninstall Java and install again, this worked for me

Eclipse crashed and deleted all project files, including written by me and XML files from another program which were not related to Eclipse.
Is it possible to force Eclipse or JVM to use trash can, so that if it goes mad and delete everything, files could restored.
UPDATE
Files were definitely wiped out. This was checked with third party file managers. Also entire disc were searched for traces.
Some good news is that Eclipse history remained. This allowed to restore some files I changed from Eclipse. But this project was consisting of multiple other files, that were written not by me (taken from other libraries) or contained some data I was editing not in Eclipse (like XML or raw data).
All these files were wiped out by Eclipse.
If this would not happen to me I would also say it is unlikely. But it has happened.
The problem is somehow related with
(1) Eclipse
(2) Maven (m2e)
(3) Eclipse RCP
(4) Tycho
At some moment Eclipse started to show numerous error windows and I was to kill the process. After that I found files absent.
So I need some extra protection layer.
UPDATE 2
Crash repeated. This is a message during file wiping out:
This time I was not using Maven and Tycho.
UPDATE 3
Third crash.
Crash occurs only after error Application ... could not be found in the registry, which itself buggie.
UPDATE 4
Still unable to reproduce situation from scratch...
UPDATE: I think from this question you were working on an Eclipse RCP plugin or something like that when this happened.
So you probably broke your Eclipse in some fashion. Do not trust anything Eclipse tells you at this point! Look at the actual filesystem!
Eclipse crashed and deleted all project files, including written by me and XML files from another program which were not related to Eclipse.
That's highly unlikely. (Especially if those XML files were not in the workspace. But even if they were, it's very unlikely.) You probably opened a new workspace without realising it, or maybe Eclipse has some bug where it won't show you files that are actually there. Or maybe you accidentally switched to the wrong view (in Java the normal view for files is Package Explorer, if I remember correctly).
Or maybe you were storing your workspace on a USB stick (aka pen drive) or network drive and you accidentally disconnected from it without realising it.
Check in the workspace (the actual workspace you were using at the time, not the workspace you are now using, which, as I said, might not be the same thing), using Windows Explorer (if you are using Windows) or Finder (if you are using a Mac) or using ls (if you are using something else). Are the files really gone?
This Was My Fault
I was setting up a workspace location pointing to project folder and also setting clear workspace checkbox.
::shame::
I have Eclipse Juno and Force.com IDE. When I try to create new classes they always show: failed to create the part's controls. It worked for the first time, but now they always show this. Same happens if I create them inside the force.com platform.
Error details:
org.eclipse.core.runtime.AssertionFailedException: assertion failed:
at org.eclipse.core.runtime.Assert.isTrue(Assert.java:110)
etc ...
I would appreciate all help.
I had the same error. I fixed it by switching the eclipse workspace. Go to menu File->Switch Workspace->Other, and then select the same workspace you were working with. Eclipse will restart and you should not get the error.
I faced the same issue my default editor for JSP was Web page editor. Which I changed to JSP editor and everything is fine.
PS: To change to JSP editor
Right click on JSP page -->open with jsp .
I got the "failed to create the part's controls" error one day when I opened Eclipse and tried to view a java file I had been working on. When I opened the file I needed, it showed a red X and NullPointerException instead of the code. The error log mentioned "event loop exception" for some reason.
I restarted Eclipse, and the error was still there. I cleaned the project, updated the project, deleted and re-imported the project, deleted and re-imported the file, and the error still was there. As a last resort, I restarted Eclipse again and then the file was fine. So one of the clean/update/delete/import steps worked but I don't know which one.
Use eclipse -clean from command prompt to solve this problem.
I solved my problem like this:
This problem occur because of in eclipse default editor is not able to identify extension of that file. If you right click on file and open it with respective text editor ,problem will be solved
In ecllipse, every file types has some associated default formats and one of the default format set to the particular file type.
You can see this in General -> Editors -> File Associations-
This issue generally occurs when we open any file in the format which is not the default format of the particular types.
I got same issue when I opened one of the Java file in text format in ecllipse and then I started getting the same issue. After research, I observed that AspectJ/Java Editor was setting as default. After reset it to Java Editor, the problem got resolved.
Steps :
1. General -> Editors -> File Associations-
2. Select the content type and choose the default format for it.
3. Restart the ecllipse.
In general, it is some default file format that set in ecllipse causing the same issue.
in my case problem was that the server was resin and I didn't have the resin server extension installed
I solved the problem.
(1)Open the filed with TXT.
(2)Search and Delete the underline between number like:
int a = 10_000;
It works when i compile and run as others used, but it will fail if i save and open again.
I also had for the same problem and fixed it by updating eclipse. Help > Check for Updates.
This worked for me---->
Right click on pom.xml-->open with-->xml editor
Had a similar stacktrace on failed to create the part's controls while trying to open Git repositories view in Git perspective.
My case (cause) is different since I was migrating an Eclipse workspace from an Ubuntu VM to Windows.
Many thing were copied like projects, .git folders, or also .metadata Eclipse folder.
Tried with no success:
uninstall all egit component (installation details, then, install new software
restart eclipse -clean
reset Git repository perspective
I searched and found this invalid UNIX : separator in .metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.egit.core.prefs file.
GitRepositoriesView.GitDirectories=/path1/.git\:/path2/.git
Here, the : is invalid path separator on Windows.
I simply removed the value in this line, saved file, and restarted Eclipse:
GitRepositoriesView.GitDirectories=
(alternative: if needed, try to migrate those linux paths to their Windows equivalent too)
Git repositories view is back.
I have an eclipse plugin which is failing. I developed/enhanced it based off of another plugin. When I deploy this plugin as an update site and install it into another instance of eclipse, it works initially (the view shows up). But as I try to interact and use the view, it's functionality is broke (it doesn't do anything when I click a given button). I don't see any error on the screen and nothing in the Eclipse Error Log view shows up.
I want to know where/if it has any error log files by default? If it had any custom loggers where would these sent to? I'm using Eclipse 3.7 (Indigo).
If I want to find out the cause of this exception must I implement my own custom log files?
Well, The error log file will be in your "eclipse workspace"\.metadata\.log
But that's just the file that shows up in the Eclipse Error Log view.
If the plugin you are using had some sort of extra logging (I doubt it) the logical place for it would be "eclipse workspace"\.metadata\.plugins\{plugin.name}" although that depends on the application..
If your application works when you debug it, but doesn't work when you deploy it, it's probably some sort of deployment issue.. Eclipse can be very very picky about picking up new versions of jars. Make sure you update your manifest version or delete your work space before doing an install. Another thing that can happen is you are missing plugins or plugin fragements that are needed or the minimum version specified isn't correct.
You don't have to implement logging. You can use eclipse to attach a debugger to your deployed application and then debug the application as you would normally. Although, if you plan on selling your application, logging is always a good idea :)
Go to eclipse installed directory and inside .metadata folder there will be a log file without name. That will be the plugin log
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.
Eclipse was working fine just a day ago. But today, when I click the eclipse icon, it only loads the splash screen and nothing else thereafter, I even don't get to see the splash screen which contains that 'green loading sign' at the bottom, and -- while monitoring the eclipse.exe in Windows Task Manager(just after starting eclipse) -- I saw that even after the splash screen went off the screen, the eclipse.exe process went with it, after a few seconds. Keep in mind that I did NOT see any warning or error messages because, (I'm assuming, that the loading haven't gone to a point where it is capable of sending any error message)
Hence, I tried reinstalling eclipse, by copying from INSIDE the .zip directory of the installation folder and pasting it inside the eclipse program directory. But the exact same problem persists. So, now I'm currently downloading the latest version of eclipse to retry again.
Any other Advice?
UPDATE
It turned out that the hard drive containing the workspace was partially corrupted, hence I cleaned it; following that, the workspace data was still accessible. (Though usually I still keep a backup on hand.)
just delete the .metadata folder from workspace and reload the eclipse. It worked for me.
Hoping you have the links to the update sites for your installed plugins, my advice is to download eclipse, download your already installed plugins from their update site's and then open the new eclipse and set the workspace to your actual workspace. More far than that is to trash your time... trust me.

Probably something went wrong with Java. Try re-installing Java run-time.
It also can mean a problem with the eclipse.ini file (like an extra space at the end of the line), or a problem with the JVM path (since the splash screen is displayed by the eclipse.exe, before loading all the eclipse Java classes).
Check that eclipse.ini file and consider my ini file as a good optimization source.
If your workspace has been corrupted your safest approach is to create a new one.
I would actually strongly suggest that you reinstall everything that might have been corrupted, to avoid as much strangeness as possible. This includes the underlying OS.
I have tried out both
(1)E:\eclipse-standard-luna-RC3-win32\eclipse -clean in run
(2)deleting .metadata folder from workspace
I do not which one worked for me.Thanks...
