Eclipse is unable to open, have used eclipse before and has open before without a problem. Now I keep getting the following error message:
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations:
Have gotten eclipse to open and work on projects before and won't open.

You can explicitly tell Eclipse where to find it. Open eclipse.ini
and add the following lines to the top of the file:
Update: I just nailed down the root cause on my own Windows machine. The GlassFish installer complained with exactly the same error message and after digging in GlassFish forums, the cause was clear: a corrupt JRE install on a Windows machine. My JRE came along with the JDK and the Java 6 JDK installer didn't install the JRE properly somehow. A DLL file was missing in JDK's JRE installation. After I reinstalled the standalone JRE from http://java.com, overwriting the old one, the GlassFish installer continued and also Eclipse was able to start flawlessly without those two lines in eclipse.ini
.
It usually is because:
- you indicated the wrong jvm path in your
-vm
argument: see this SO question for an concrete example. - the
eclipse.ini
got corrupted somehow (if it hasn't been modified, this isn't it, but if setting a jvm path doesn't work, ... I would replace theeclipse.ini
by one coming from a fresh installation just to be sure) - the java which eclipse search by default is no longer accessible (because the $PATH is no longer up-to-date)
More details on the wiki page 'Finding a VM, Using JNI Invocation or Executing Java'
No -vm specified
When no -vm
is specified, the launcher looks for a virtual machine first in a jre directory in the root of eclipse and then on the search path.
If java is found in either location, then we look for a jvm shared library (jvm.dll on window, libjvm.so on *nix platforms) relative to that java executable.
- If a jvm shared library is found we load it and use the JNI invocation api to start the vm.
- If no jvm shared library is found, we exec the java launcher to start the vm in a new process.
As mentioned in 'FAQ How do I run Eclipse?':
Eclipse DOES NOT consult the JAVA_HOME
environment variable.
So I would check your $PATH, starting by n new shell sesion (whatever your OS is), typing 'java -version
' to see if it still returns anything.

I had the same problem and the issue was that I had a 32 bit version of Eclipse running on my 64 bit machine and it wanted the 32 bit version of JRE.
I changed Program Files
to Program Files (x86)
in the eclipse.ini
file like so:
and that solved the problem.
You may want to just install the 64 bit Eclipse, but this will take care of the error.
Here is how I fixed mine:
find the location where your jre is installed. in my case, it was located at C:Program FilesJavajdk1.7.0_10
copy the jre folder and paste it where your eclipse files are located (where eclipse.exe is located).
when you download eclipse, you get a .zip package containing eclipse.exe and all the other files needed to run eclipse but it is missing the jre files. so all you need to do is to find where jre folder is located on your hard drive and add it to the rest of the eclipse package.
Copy javaw.exe from C:Program FilesJavajre1.8(or)1.6(or)1.7bin
and paste it inside Eclipse folderwhere eclipse.exe is there. That's all.
Did you install Java via the java.com web browser auto install? If so, then that's your problem! You need to to the 'manual' install: http://www.java.com/en/download/manual.jsp
It's just a matter of having the correct match of 32-bit Eclipse/32-bit Java or 64-bit Eclipse/64-bit Java. Many 64-bit Windows have 32-bit browsers and the latter is the version of Java that the auto-installer will provide - not what the 64-bit Eclipse wants.
Make sure the install path of JDK is in your Path variable in Windows.
I also had same problem when developing android applications using eclipse IDE.I solved it by removing all the java installations (I had java 6 and 7 both) and re-install only jdk 7.
adding -vm C:/Program Files/Java/jdk1.6.0_29/bin/javaw.exe
to the .ini file helped me.
I got this fixed by doing the below steps,
1)
- The eclipse finds the JAVA executables from 'C:ProgramDataOracleJavajavapath'
- The folder structure will contain shortcuts to the below executables, i. java.exe ii. javaw.exeiii. javaws.exe
- For me the executable paths were pointing to my (ProgramFiles(x84)) folder location
- I corrected it to Program Files path(64 bit) and the issue got resolved
Please find the screenshot for the same.
Just to add on top of other answers:
Windows Users: You can give the PATH to JRE in eclipse.ini separated by '/' or '. It doesn't matter. Eclipse will pick it anyway. For example, in my windows system, either of the paths is fine (after -vm of course):
C:/Program Files/Java/jre1.8.0_181/binor C:Program FilesJavajre1.8.0_181bin
Is so simple,only add your java path for example:
C:Program FilesJavajdk1.8.0_121bin
in PATH system variable
I have faced the similar issue earlier with Eclipse and STS IDE'S
- Please check weather
JDK/JRE
is available or not in your machine. If not please install JDK and setup the environment variables. - Even after step 1, if you are still facing the issue then it's time to set the vm argument in
eclipse.ini
or sts.ini in the following way.
I had this problem too on a win7 machine.I wanted to update the jre with a jdk. So i deleted the jre folder and downloaded and unzipped the new jdk.The issue was i manually deleted the jre folder, when instead i should've uninstalled it. This leaves a bunch of registry entries that still point to the old jre. Somehow eclipse still wants to use the old jre.I couldn't uninstall the old java vm, i kept getting this error:
Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor
So i had to use this MS utility to fix the uninstall:
Then i had to install again the vm. I installed to the same location the original one was at, to avoid losing another hour! After that eclipse started correctly.

I just had this problem and fixed it this way. I noticed the error message has jre in it not jre6 or jre7, so i copied jre6 from program files to eclipse folder then renamed it from jre6 to jre, then it worked :p
Newb move on my part, but I had installed just the JRE instead of JDK. Installed JDK and my problem went immediately away.
I had this problem and it was due to my windows machine playing up. I went into control panel -> system -> advanced - environment variables.
I edited the PATH variable (which was already correctly set up), changed NOTHING, clicked OK to come back out of the screens.
Then eclipse worked. No idea why, except because windows. Hopefully this may help someone.
I had this issue; I fixed it by going to
Computer-->Properties-->Advanced Settings-->Environmental Variables
In the System Variables find the variable named PATH.
-->Select Edit-->At the very end of the Path Variable, put a ';' then add your path of your JDK and put bin at the end
Should be fixed.
Example:
System Variable-
C:Program Files (x86)Common Files.......HPLeanFTbin
JDK path-
C:Programs FilesJavajre1.8.0_121
Final Path -
C:Program Files (x86)Common Files.......HPLeanFTbin;C:Programs FilesJavajre1.8.0_121bin
Sources:https://www.java.com/en/download/help/path.xml
Its simple.JDK bin directory or JRE bin directory should be in path variableExample :Java Installed directory:Assume your java installed in 'C:Program FilesjavaJdk1.8.0_144' directoryNow you can find bin directory in 'C:Program FilesjavaJdk1.8.0_144bin'
Navigate to user's environment variable
In popup click Path under User variables for sectionClick Edit... button and another popup will appear
Click New button and enter C:Program FilesjavaJdk1.8.0_144bin
Click OK button and again OK button in Environment variables popup.
Now you can open your eclipse without error
I found a solution wherein the Eclipse.ini the location was the old version of Java, and after updating the new version of java the location of -vm
C:Program FilesJavajre1.8.0_201bin
was same so I had to change the directory to my new version of Java.
So solution is to just open the most updated Java version and copying its directory path and replacing it in the Eclipse.ini file.
Moderately future proof example for Linux-like systems. Assuming javac installed and on your path.
./eclipse -vm dirname $(readlink -f $(which javac))
This will find the directory where javac is installed, and pass as vm argument to eclipse.
