That sounds pretty bad and weird. But reinstalling isn't that hard - download, unzip, change the default memory allocation, run Eclipse, install necessary plugins and features.

And almost all of the important preferences are in your workspace. The only important one I can think of outside of the workspace is the aforementioned memory allocation, which you can set on the command line or in the ECLIPSE.INI file.

Restart the machine. Solve your problem. Sometimes it happens when you are trying to restart the eclipse and in-between forcefully close it.

open eclipse.ini and replace with this ~

-startup

You might changed your drive-letter: once u had installed eclipse on D:\, after windows reinstall the drive-letter is now E:\ (for example).

look into eclipse.ini in your eclipse folder, there are some lines where the drive-letter is still D:\

This happened to me when I tried to open eclipse.exe before the .zip file finished extracting. Make sure all dependencies are unzipped or unpacked before opening the .exe.

I had this issue on Linux (CentOS 7 64 bit) with 32-bit Eclipse Neon and 32-bit JRE 8. Non of the answers here or in similar questions were helpful, so I thought it can help someone.

Equinox launcher (eclipse executable) is reading the plugins/ directory and then searches for eclipse_xxxx.so/dll in org.eclipse.equinox.launcher.<os>_<version>/. Typically, the problem is in eclipse.ini pointing to the wrong version of Equinox launcher plugin. But, if the file system uses 64-bit inodes, such as XFS and one of the files gets inode number above 4294967296, then the launcher fails reading the plugins/ directory and this error message pops up. Use ls -li <eclipse>/plugins/ to check the inode numbers.

In my case, moving to another mount with 32-bit inodes resolved the problem.

I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.

The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):

%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash

After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.

To be clear, you'll have to modify your javaw.exe command to match your system specifications on MS Windows.

I got similar error sometime back. I had copied the eclipse setup from another laptop to mine. The issue with my setup was that path of the "--launcher.library" in the eclipse.ini file. The path in --launcher.library was that of the old machine and hence I was getting the error

I changed the path of "--launcher.library" in eclipse.ini to the path of eclipse on my laptop and the issue got resolved. I hope this is helpful to someone is getting this error.

I had this problem. I read through all of the answers here. Several of the answers allude to the need to run as admin. It appears this is a common issue with IDEs in modern times on Windows. I notice Android Studio also exhibits a very similar behavior. While some individuals suggest reinstalling, that in itself doesn't feel very satisfying to me. I have found a horrible "hack" to circumvent having to reinstall or having to run as admin. If you copy the .p2 folder to the ALL USERS folder. You then open the INI file and everywhere you see the admin user directory, replace with the ALL USERS directory. While this feels somewhat hookey, I like this approach because it behaves like an installer that asks if you wish to install the product for the individual user or for all users. The Eclipse installer does not give that option. Worst still, worse than even a similar problem with Android Studio, is that if you choose some "shared folder" (like Program Files") for the install, then only that one user can ever use Eclipse.

Mostly this is related to problems on windows with the unzipping it seems. (See other answers here for that).

The second largest issue seems to be that eclipse is not able to find java or finds a java version which is too old or even older eclipse installations.

Here's another take to the latter problem and a small twist to solve it. My work environment is on a linux system, without root access, and with software installations where I can configure which versions to use in a kind of config file. However I have no influence on the way those software packages are installed and they are immutable to me.

I download and untar the latest eclipse as usual to a user disk for which I have write permissions. Then I configure myself an alias to always temporarily cd into the eclipse installation when starting. That regardless of where I work on the file systems, eclipse always finds its correct libraries. It seems in some places, eclipses default search path for java digs out an installation (of java or older eclipses or sth else) in my environment that it really should not use.

Here's the alias: alias eclipse '(pushd /enter_path_to_eclipse_install_dir_here/eclipse ; ./eclipse ; popd)'

Now you can start it normally from e.g. your project or arbitrary work directory:

eclipse

Or also put it in the background

eclipse &

Maybe this helps for people in convoluted work environments.

I faced this issue recently: (In my case it was installation of STM32CubeMX software):

what I faced: I have two users in my laptop, I had installed the software in one user but on the hard disk partition: D:\ Now I had tried to work on another user! -- I think you know why I got the error -- So as I was working on the 'other' user account, I got this error every time I tried to compile/build my project - obviously, Because I installed using one user and am working on another.

Workaround: Already mentioned in the above answers clearly!

What I did differently: I tried using the S/W in the other user, but there seems to be issues on the path file/location: so I reinstalled the location in the user account I want to use and am running it properly now!

Note: While Installing it did ask about installing the software for all user/ current user : I mistakenly had given 'current - user' =(

My experience and advice: Install Eclipse Juno on C: drive.

After download the zip, put it on C:, click the right mouse button -> extract here. Then a folder called eclipse will be created in C: drive.

Then go to Eclipse executable, run it, and all will be ok.

I meet this issue after copy a eclipse installation to another pc.I find the eclipse installation auto created the .p2 directory on my c:\Users\xx.p2, and --launcher.library refer to here.So it doesn't exist on my another pc.
My resolution is to reinstall eclipse:
a)Double click eclipse-inst-win64.exe
b)Click to change to advanced mode.
c)Uncheck the Bundle Pool
d)Finish your installation and copy again.
Everything will work well.

I just ran into this myself and found that, indeed, as one post above stated: using cygwin and gunzip or unzip to set up your eclipse environment the permissions on the .exe and .dll files will be incorrect and the JVM will not run them properly.

Quick solution:


#switch to the eclipse target folder
cd /cygdrive/c/Program\ Files\ \(x86\) #or wherever you put eclipse
find ./ -regextype posix-extended -mindepth 1 -type f -regex ".*\.exe|.*\.dll" |\
xargs chmod -v 750

Another problem (that I ran into) is that Cygwin's unzip utility (UnZip 6.00 of 20 April 2009, by Cygwin. Original by Info-ZIP.) does not always correctly unzip everything needed for Eclipse to actually run.

Using 7ZIP v9.20 got Eclipse Indigo (3.7.2) up and running for me on Win7 64bit with 32bit JVM and 32bit Eclipse.

(First time I've ever had Cygwin's unzip fail on me...)

I have seen this in MacOS Sierra. Sometimes unzipping the app leaves extended attributes that seem to prevent the startup. The following command line removes extended attributes and seems to fix the problem:

xattr -c Eclipse.app

It also works for other applications that are built on the eclipse framework.

During unzip in a cygwin directory on Win7, .exe and .dll need to be given executable mode. This is the solution from a mintty (or other $TERM) terminal run with cygwin on windows 7:

me@mymachine ~/eclipse
$ find . -name "*.dll" -exec chmod +x {} \;

tried with Juno (eclipse 4.2) freshly unzipped, cygwin 1.7.something

Check eclipse.ini, there are two entries like:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120913-144807

For some twisted reason jars have version in their name - so if you upgrade/have two different version of eclipse( while eclipse.ini is either linked or provided as system wide conf file for eclipse ) it will cause above error.

I've just encountered the same issue. The problem for me was Windows 7 default unzipper program. It has a problem when it encounters files that have a deep file structure. I read about this issue some time ago but can't recall the article. Fix for me is to unzip the Eclipse download using WinZip (or some other tool which does'nt have this issue).
