I just rebooted my computer without changing anything. Suddenly I can't open Eclipse. Instead, I get this error message:

┌──────────────────────────────────────────────────────────────────────┐

And I see all my environment variables have been erased. java, javac, mvn, etc. don't work. What do I do now, and how do I fix this?

Let eclipse use your java vm directly!

Put these lines at the end of eclipse.ini (located in the directory where eclipse.exe is present):

-vm
<your path to jdk|jre>/bin/javaw.exe

Pay attention that there are two lines. Also make sure that the -vm option is before the -vmargs option (and of course after "openFile").

Here is the answer, sorry .. but your solutions weren't correct 

set PATH=C:\Program Files\Java\jre1.6.0_03\bin ;%PATH%

paxdiablo Did you rewrite the error or you got some kind of software reading text from image, if you got which one ?

Another alternative is to re-run the JRE setup. It typically installs a default JRE by placing java.exe, javaw.exe, etc. in your system folder. That would place the executables in your path, which should be sufficient, based on the note in the error message that it searched your path for javaw.exe

very easy, you just copy the folder 'jre' to the folder that you put eclipse. That'all. Jre is the environment, normally it's location in the C:/Programing Files/Java/jre :D
