2511. Checking Which JDK Eclipse is Using
JDK and Eclipse

How to check which JDK Eclipse is using.

1. JDK & Eclipse

For some reasons, we may install multiple versions of JDK on the same development machine. In this case, we may want to know which JDK version is used by Eclipse.

2. Checking Version

To check with what Java version (JRE or JDK) Eclipse is running, do the following:

  • Open the menu item Help > About Eclipse. (On the Mac, it’s in the Eclipse-menu, not the Help-menu)
  • Click on Installation Details.
  • Switch to the Configuration tab.
  • Search for a line that starts with -vm. The line following it shows which Java binary is used.
-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/../jre/lib/server/libjvm.dylib
