Eclipse does not start when I run the exe?

Question

When I run the Eclipse.exe within the given folder, it will not start. The Eclipse splash screen will appear for a split second then close. There are no errors.

I've tried practically everything. Updating JDK and JRE: I installed JRE 7 and JDK 1.7.0_40. Both 64 bit, and they are both in the (x86) folder. I've tried re-installing them. And re-downloading Eclipse. Same result every time. I've added the VM to the config, still nothing.

I use Windows 7 and the standard Eclipse for Java IDE.

IF it Windows, Right click on My Computer, Click Manage. It will open the Computer Management, and goto Event Viewer -> Windows Log -> Application, will display the exact error message for unsuccessful Eclipse launch. Can you please update your question with that error code and msg? — Viji, Sep 29 '13 at 22:10
Post the log from /.metadata/.log, or if you never selected a workspace, look for a *.log in the eclipse directory. — Fredrik, Sep 30 '13 at 07:46
Just uninstalling Java 8 update 45 made my eclipse work. Thanks @Michael. — Manish Gupta, May 06 '15 at 10:51
I have same Windows 7, and I have download the same version from http://sourceforge.net/projects/eclipse.mirror/ And It works just fine. Can you uninstall and install it again? — Viji, Sep 29 '13 at 22:47

Go to your Workspace folder then go to Metadata > plugins. Delete everything from this folder. Then it will work.

Warning: This will delete every configuration from Eclipse!

This worked for me. Recently installed a new plugin which apparently fails. Too bad that you can't delete a specific plugin and save some time reinstalling all the ones that actually work. – Stan Mar 10 '14 at 06:51
The .metadata folder is an area where Eclipse plug-ins can save any information they want to save. http://stackoverflow.com/a/19996319/2362301 – AmmY Jun 20 '14 at 04:53

eclipse.exe -clean -clearPersistedState

All you have to do is go the dir where your eclipse.exe is there and run the above command

I looked online and found a person who had a similar problem.

It says on the forum

"You might need to download JRE 64 bit version"

But again, it depends on what OS you're using as well.

Kindly check the following:

1) Your eclipse version,whether it is compatible with what version of java. Have that.

2)Check the operating system specific BIT requirements either 32/64 with eclipse version.

3)Usually java will be installed in ProgramFiles for Java if both OS & Java are 64 bit else it will be in ProgramFiles(x86) if java is 32bit and OS is 64Bit.

4)Last but not least check the environment variables for Java whether it meets the requirements of your eclipse version.

Hope this Helps you!

Yep, my other version of eclipse was 64-bit, so I needed a 32-bit java. — M_M, May 30 '18 at 10:57

What system you have - 32-bit or 64-bit? You say it was installed into (x86) folder. But normally (x86) is a default for the 32-bit JDK, not for 64-bit JDK. If you used defaults, then it seems that you installed 32-bit JDK instead of 64-bit.

No, I'm 64 bit. And I have 64 bit JDK and JRE. Which are in both "Program Files" and "Program Files (x86)" – Calum Richards Sep 29 '13 at 22:18
Are you sure you downloaded 64-bit eclipse not 32-bit? – mentallurg Sep 29 '13 at 22:21
No I definitely have 64-bit eclipse. I even tried downloading the 32 bit to see if that worked. But no. I'm positive I have the 64 bit. – Calum Richards Sep 29 '13 at 22:30
Launch console (cmd.exe), go to your eclipse directory, laucnh eclipse.exe. There may be some exception on some error message in the console. Put it here, then we'll see what to do further. – mentallurg Sep 30 '13 at 12:09

The actual issue should be with the OS architecture, the JDK (32bit or 64 bit) installed and the eclipse type u installed.

Bring them in sync, things would work completely fine.

Just have a check at the Eventlog as mentioned by @Viji Ideally u should encounter error like RADAR_PRE_LEAK_64

If its a Java version problem, you can edit the eclipse.ini file and assign the compatible version to the application through adding these lines:

windows example:

-vm
C:\jdk1.7.0_21\bin\javaw.exe

I had a similar problem with Eclipse mars. It suddenly over the weekend stopped working and if you ran it from a command window (Windows x64) it would flash up a line or two and then stop.

I installed Eclipse neon yesterday and it worked, but today it stopped working and went wrong in the same way.

Just now I installed the JDK from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

I installed version 8u101 and then neon started. I have not changed eclipse.ini (although I had a look at it) nor have I deleted the plugins (I renamed the folder and found that this had no effect).

Hence I think this difficult to work out problem relates to the JDK/JRE. It would be nice if Eclipse gave a bit more information to go on, but such is life.

I just had this issue in Eclipse Neon. After trying all these suggestions, it turned out that in my case the problem was improperly configured path variables.

There is a pretty good answer already posted here which explains it, but I'll summarize it in this answer for convenience.

You will need to go into your User Environment Variables panel and modify the following values:

JAVA_HOME : C:\Program Files\Java\jdk1.8.0_102
JDK_HOME : %JAVA_HOME%
JRE_HOME : %JAVA_HOME%\jre
CLASSPATH : .;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
PATH : your-unique-entries;%JAVA_HOME%\bin (make sure that the longish your-unique-entries does not contain any other references to another Java installation folder.
