Eclipse/Installation
https://wiki.eclipse.org/Eclipse/Installation

Current releases of Eclipse require Java 8 or newer. If you are using Eclipse to do Java development, install a JDK. In all cases, 64-bit Eclipse requires a 64-bit JVM, and a 32-bit Eclipse requires a 32-bit JVM.
A Java Development Kit (JDK) includes many useful extras for Java developers including the source code for the standard Java libraries.

If using Java 9 or newer please use Eclipse 4.7.1a or newer as it contains fixes in Eclipse launcher to add all JVM modules.

Be sure to install a JVM with the same bit level as Eclipse
i.e. install a 32-bit JRE to run 32-bit Eclipse; install a 64-bit JRE to run 64-bit Eclipse

Configure Eclipse to use the JVM

It is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse.ini This is a very important step to be sure that Eclipse is using the JVM you intend and can't be influenced by any other software that might alter your system. The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions.

• The -vm option must occur after the other Eclipse-specific options (such as -product, --launcher.*, etc), but before the -vmargs option, since everything after -vmargs is passed directly to the JVM.

-vm
c:\Java\jdk08\bin\javaw.exe
-vmargs
