In summary, if you are trying to figure out where JAVA_HOME is on your Mac OS X system, I hope this has been helpful.How do I find out what version of Java I have on my Mac? Mac OS X 10.7. You might also be able to find some of these settings in the Mac OS X Control Panel, but I looked just now, and did not see them (though you can see Java's "temporary internet files" from that console). If you have XCode installed you can now find the JAVA_HOME directory with this command: I have no way of verifying this any more, but on Mac OS X 10.5, 10.6, and 10.7, I'm pretty sure this is where the JDK JAVA_HOME was located: Library/Internet\ Plug-Ins/ugin/Contents/Home/bin/java -version Older Mac OS X systems This is confirmed by this Oracle Java/JRE documentation page, which shows that you can demonstrate this by running this command in the Mac Terminal: Library/Internet Plug-Ins/ugin/Contents/Home If you've installed the Oracle JRE (as opposed to the JDK), JAVA_HOME for it appears to be located here instead:
Of course that will vary by the JDK version you have installed. Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/
This has changed over time, but if you're using Mac OS X 10.9 or newer (now macOS), your JDK/SDK JAVA_HOME location for Java 8 will be something like this: Java/Mac FAQ: Where is JAVA_HOME located on Mac OS X (macOS) systems? macOS JDK location You can now hire Alvin Alexander for Scala or Flutter side projects!Ĭontact me at (al) at valleyprogramming (dot) com for details.
