when I start my IDE) to use the latest "early access" version I have for now. Usually I have the latest stable one for general use, and others for tests. As far as I can tell, none of the current answers do that (*).Īs a developer, I use several JDKs, and I want to switch from one to the other easily.
UPDATE ERROR FOR LATEST JAVA ON MAC HOW TO
This answer is an attempt to address: how to control java version system-wide (not just in currently running shell) when several versions of JDK are installed for development purposes on macOS El Capitan or newer (Sierra, High Sierra, Mojave). Press Y to save your changes source ~/.zshrc zshrc file should work: nano ~/.zshrcĮxport JAVA_HOME=$(/usr/libexec/java_home -v 1.8.0) Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)Īdd the export JAVA_HOME… line to your shell’s init file.įor Bash (as stated by antonyh): export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)įor Fish (as stated by ormurin) set -x JAVA_HOME (/usr/libexec/java_home -d64 -v1.8) Now when you run java -version you will see: java version "1.6.0_65" Or you can specify just the major version, like: export JAVA_HOME=`/usr/libexec/java_home -v 1.8` Pick the version you want to be the default ( 1.6.0_65-b14-462 for arguments sake) then: export JAVA_HOME=`/usr/libexec/java_home -v 1.6.0_65-b14-462` Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home This was the stupidest thing Oracle could do with Java.First run /usr/libexec/java_home -V which will output something like the following: Matching Java Virtual Machines (3):ġ.8.0_05, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Homeġ.6.0_65-b14-462, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Homeġ.6.0_65-b14-462, i386: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home Oracle specifically BROKE the Java sandbox, allowing Java to interact directly with computer systems. Why is Java over the Internet now so dangerous? Thank Oracle, who obtained Java when they bought Sun Microsystems. Check up on their reputation and verify they are NOT Trojans. So avoid running mysterious Java apps you know nothing about. Trojan horse Java applications are possible. Just be sure you run Java apps, off the Internet, from reliable developers. NOTE: Running Java applications off the Internet is not typically a problem. But for the sake of simplicity and the ability to reinstate the Java Plug-In whenever you may want to actually use it on the Internet, I'd leave everything else in place. There are other Java bits and pieces you could trash. Java now cannot run in them over the Internet, which is where Java is particularly dangerous.
I have them in a folder labeled "Internet Plug-ins (disabled)" inside the Library folder.ģ) QUIT and restart all your web browsers. I advise that you store these files somewhere, just in case you want to use them later for some odd purpose.
Yes, that includes Apple's own alias file "ugin". A quick and simple way to DISABLE running JAVA over the Internet (if you have Admin privileges):Ģ) Remove from this directory everything listed as 'Java'.
