1  Open the eclipse ini file from your eclipse folder see the picture below     2   Open eclipse ini in Notepad or any other text-editor application  Find the line -Xmx256m  or -Xmx1024m   Now change the default value 256m  or 1024m  to 512m  You also need to give the exact java installed version  1 6 or 1 7 or other      Like This   -Xmx512m -Dosgi requiredJavaVersion 1 6   OR  -Xmx512m -Dosgi requiredJavaVersion 1 7   OR  -Xmx512m -Dosgi requiredJavaVersion 1 8   Then it works well for me

The proper solution to your problem is to add the -vm line pointing to jvm dll file of your Java folder in ini fie   -vm C  Program Files Java jre1 8 0 202 bin server jvm dll   there is no dquote for path  and path points to right java version folder mentioned in ini file     If the above fix is not fruitful  then do not attempt anything else  Most of the advice in this thread is misguided  Some of these hacks might work temporarily or on certain machine configurations  but the contents of eclipse ini are not trivial nor arbitrary  For the authoritative reference  see this  wiki page  https   wiki eclipse org Eclipse ini Specifying the JVM that explains the contents of the file  Also note the See Also links at the bottom of that page for more details about things like heap size  etc  DO NOT delete eclipse ini  EVER  It is also inadvisable to remove the -vm or Xmx options  If you do  you re asking for trouble   Here are references from the wiki page pertaining to your problem

Try to add  -vm D  Java jdk1 6 0 29 bin javaw exe   FYI  Refer sunblog  For others who might have problems with Java 7  as per Eclipse Wiki - eclipse ini vm value  windows example      This might not work on all systems  If you encounter  Java was started but returned exit code 1  error while starting the eclipse  modify the -vm argument to point to jvm dll   e g   -vm C  Program Files Java jre7 bin client jvm dll   Also note that      The -vm option must occur before the -vmargs option  since everything after -vmargs is passed directly to the JVM
