I am facing a small issue and need help on it. I had to re-install windows on my laptop, after that i installed Java extracted eclipse and set the environment variables, namely Path to the java bin directory and also created a JAVA_HOME variable and set it.
Every time i try opening eclipse.exe i get the following error.
The eclipse executable launcher was unable to locate its companion launcher jar.
can some one help me out please and tell me what i am missing here?
My eclipse.ini :

I just installed eclipse on my windows 8 computer and I get this error when trying to run eclipse. I'm not really sure whats going on I already have the Java SDK on my computer.
Error message:
My Eclipse.ini text file (its just one long line in textpad):
-startup

Try right clicking on the eclipse icon and "run as administrator", worth a shot!
Fixed it by adding:
-vm
C:\Program Files\Java\jdk8\bin\javaw.exe
before -vmargs
Make sure there is a new line after -vm

Make Sure you are following these steps.
1) Install jdk(1.6 or 1.7) and set the path in enviornment variables.
2) Download android SDK ADT bundle from Android developers site.
3) Thats all you need to do basically.
Now, if you are getting "Failed to create the java virtual machine".
What you have to do is, edit your eclipse.ini file. Which is there in eclipse
folder.
And write the following line in eclipse.ini file.
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar

Imp Note: Replace **C:\Java\jdk1.7.0_29\bin\javaw.exe** with your path.
I am trying to update my eclipse to work with a jdk and not a jre.
I followed the instruction in this forum , also search google for answers but for some reason it still don't work.
I try'ed going to preferences ->java->install jre's , removing the old jre from there and using the path for the jdk.
also try'ed going to project properties -> java build path -> jre system libraries -> edit-> workspace default jre.it also says there i'm using jdk.
I even try'ed adding to the ini file the next path C:\Program Files\Java\jdk1.6.0_31\bin\javaw.exe
but when i try'ed deploying my program to app engine i get the next message :
Unable to update app: Cannot get the System Java Compiler. Please use a JDK, not a JRE.
my eclipse version is juno 4.2 and my jdk version is 1.6.0_31
I don't know what else i need to change. I even uninstall my older jre from my computer but eclipse still don't work with the jdk ( although it recognize it )
I'm out of idea's ... anyone could help me please ??
this is my ini file :
-startup

thanks for the help
If you want to change JVM Eclipse itself should run on, the right place for that is eclipse.ini. Here are instructions on how to specify that: eclipse.ini.
Common mistakes are specifying -vm parameter name and the value in one line, or missing '-vm', or misplacing it. Also, pay attention to -vm format on different OSes.
EDIT (after .ini file published): your -vm option comes after -vmargs, which is wrong (both lines are treated as VM args). The correct parameter placement in your .ini file would look like this:
...
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Program Files\Java\jdk1.6.0_31\bin
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m
Below you can find my eclipse ini where I set a dedicated JDK via
-vm C:/Program Files (x86)/Java/jdk1.7.0_10/bin/javaw.exe
Have a look at the section "Specifiying the Java Virtual Machine" in the eclipse help.
Quote:
Tip: It's generally a good idea to explicitly specify which Java VM to use when running Eclipse. This is achieved with the "-vm" command line argument as illustrated above. If you don't use "-vm", Eclipse will look on the O/S path. When you install other Java-based products, they may change your path and could result in a different Java VM being used when you next launch Eclipse.

None of the other answers worked for me. I eventually just removed the "jre7" directory and, presto-chango, Eclipse started using the JDK that was installed next to it.
what do I need to write in my eclipse.ini to get rid of this warning:
The Maven Integration requires that Eclipse be running in a JDK,
beacuase a number of Maven core plugins are using jars from the JDK.
Please make sure the -vm options in eclipse.ini is pointing to a JDK
and verify that Installed JREs are also using JDK installs.
My ini says this and the problem is not solved:
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.2.R36x_v20101222

Update: The above definitely doesn't change my vm I checked it according to this answer and it says I'm still running eclipse.vm=C:\Windows\System32\javaw.exe
Update2: A suggested on several websites I tried to run eclipse from the commandline as .\eclipse -vm "..\Java\jdk1.6.0_25\bin\javaw.exe" and it worked!!! In "Eclipse Installation Details"->"Configuration" it now says eclipse.vm=C:\Program Files\eclipse\\..\Java\jdk1.6.0_25\bin\javaw.exe
Did you try using slashes instead of backslashes for the folder of your jdk?
As has been suggested in other answers you should both change backslashes to forward slashes in your JDK path and put -vm and the JDK path on different lines. This is what works for me:
-vm
C:/Program Files (x86)/Java/jdk1.6.0_26/bin/javaw.exe
I have these two lines as the first ones in my eclipse.ini file, but that should not be required.
Here is my eclipse.ini (eclipse 3.6) and maven works fine
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library

I just downloaded eclipse from official site, download maven 2.2.1 from apache site, installed
m2eclipse - http://m2eclipse.sonatype.org/sites/m2e
m2eclipse Extras http://m2eclipse.sonatype.org/sites/m2e-extras
(Install new software)
Set up my maven installation in Window->Preferences->Maven->Installations
and that's all for me to work with maven.
Have you tried an enter between -vm and the java path? I think it needs a new line. You can also try pointing to the jvm.dll instead of the .exe
The Eclipse executable launcher was unable to locate its
companion launcher jar.
or
This (above) error occurs when I am trying to start my eclipse, on Fedora 12. my jdk and eclipse both are of 32 bit.
And eclipse.ini as

Has Eclipse been installed through yum or manually?
Is it a new install or has it been upgraded?
From the ini file, it looks like a version mismatch between the --startup jar and the --launcher.library.
Depending on how Eclipse was installed, you can look for existence of the specified jar and the folder. Most likely one or both is missing or incorrect.
