Eclipse: Could not find Java 2 Runtime Environment

I just installed Eclipse 3.5. Before I could install the Android Plugin I needed to install a Java jdk, which I did. After restart Im not able to start Eclipse anymore, because I receive the following error:

Error: could not finde Java 2 Runtime Environment

The weired thing is, that now I cant even open my other Eclipse Installations, that I use for PHP Programming. Any suggestions?

Update:

This is my eclipse.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms40m
-Xmx256m

The simple solution that worked for me, since other resolution required admin privilege is executing the below command from command prompt

eclipse -vm C:\Java\jdk1.7.0_72\bin\javaw

Also, to make the eclipse shortcut work by editing the shortcut.Append -vm C:\Java\jdk1.7.0_72\bin\javaw in the target section

You can explicitely tell your eclipse session which jdk/jre you want it to start with adding the following in your eclipse.ini:

-vm
c:/your/jre/bin/javaw.exe

Change the PATH environment variable from something like

...;%SystemRoot%\System32;...;C:\Program Files\Java\jdk1.7.0_17\bin;...

to something like 

...;C:\Program Files\Java\jdk1.7.0_17\bin;...;%SystemRoot%\System32;...

I had the same problem when I recently installed JDK 7 Update 9. My eclipse did not open and when I run "java -version" from CMD, it did not work either. I had PATH variable set to the correct bin directory.

Anyways, eventually when I set JAVA_HOME to the new installation directory, eclipse started fine. Not sure what is the problem with JDK 7 Update 9.

In my case installing the most recent JRE worked well: http://www.oracle.com/technetwork/java/javase/overview/index.html

I had the same issue. Eclipse (3.7) worked just fine for a while with JDK 6, and then I installed JRE 5 (please don't ask me why)

This eclipse wiki page, which seems up to date, states that:

If a JVM is installed in the eclipse/jre directory, Eclipse will use it; otherwise the launcher will consult the eclipse.ini file and the system path variable. Eclipse DOES NOT consult the JAVA_HOME environment variable

And indeed, I did not change JAVA_HOME so that couldn't be it. However, at the bottom of the same wiki page, someone added:

A comment on the JVM search order (on Windows) - My testing (Windows 7, Eclipse 3.4.1) shows that Eclipse also looks for a JVM in the registry, in my case HKLM\Software\Wow6432Node\JavaSoft\Java Runtime Environment

So I found the mentioned registry entry, which now had the value of "1.5" and changed it to "1.6", then restarted my PC (windows 7), and voila - Eclipse went back alive.

I agree that adding "-vm" might fix this, although it didn't seem to work for me (maybe I didn't add it in the right place/format). But IMO, the registry fix was the better one in my case. After restarting my computer and seeing Eclipse was back to normal, I uninstalled JRE 5 (through "Add or remove programs") just to tie up loose ends.

I had a similar problem, with exception that Java was installed successfully. Once I added c:/my-path-to-java/jre/bin to PATH (system environment variable), Eclipse started successfully.

It makes sense that your PHP eclipse won't start either. Eclipse runs on java itself. Probably it cannot find the JRE.

so I see two possibilities:

  • The JRE is corrupt and you should reinstall it
  • Eclipse is getting confused by the 2 jre (unlikely to me) and you need to point it to the right one (as suggested by Dimistrisli).

Wonder if the Java install might be corrupt. Can you run the following on the Run prompt and paste what you get in code tags:

dir /d /s "%JAVA_HOME%" > "%HOMEPATH%\java2.txt" && notepad "%HOMEPATH%\java2.txt"

Make sure everything is setup correctly under "installed JREs" under the Eclipse preferences.
