Setting Eclipse's Startup Arguments

  2. In eclipse.ini, replace the following properties:
    Before After
    C:/Program Files/Java/jdk1.8.0_66/bin/javaw.exe

    In Windows, make sure the -vm argument points to the JDK's executable.

    In Linux, point the -vm argument to the directory that contains the JDK's executable. (ie. Java/jdk1.8.0_21/bin)


    Eclipse may fail to start if the values assigned to -Xms and -Xmx are too large for your system to handle. You should tweak these values to best suit your system.
