![]() ![]() In that case Step 2 above will give you /usr/bin/java -> /System/Library/Frameworks/amework/Commands/javaĪnd that particular java binary is a stub which will resolve the actual java command to call by consulting the JAVA_HOME environment variable and, if it's not set or doesn't point to a Java home directory, will fall back to calling java_home. ![]() If usr/bin/java points to another symbolic link, recursively apply the same approach with ls -l Īn important variation is the setup you get if you start by installing Apple's Java and later install Oracle's. sudo ln -sfn /usr/ local /opt/openjdk8/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-8.jdk. On my system, this outputs /usr/bin/java -> /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/javaĪnd therefrom you can read the Java home directory 2.5 The openjdk8 is also a keg-only we need to create a symbolic link so that the macOS java wrapper can find it. bashprofile set JAVAHOME and PATH as below. Dont be upset for this as a developer just needs to set PATH and JAVAHOME. ![]() Mac os jdk installation location mac os#If that gives you something like /usr/bin/java, which is a symbolic link to the real location, run ls -l `which java` Java package structure of Mac OS is a bit different from Windows. ), with the ability to explicitly specify the desired Java version and architecture, or even request the user to install it if missing.Ī more pedestrian approach, but one which will help you trace specifically which Java installation the command java resolves into, goes like this: It provides device emulation, a standalone development environment, and a set of utilities for rapid development of Java ME applications. Mac os jdk installation location for mac os#If you check out its help text ( java_home -h), you'll see that you can use this command to reliably start a Java program on OS X ( java_home -exec. Java Platform Micro Edition Software Development Kit 3.0 for Mac OS Java ME Platform SDK is a state-of-the-art toolbox for developing mobile applications. This is the natively supported way to find out both the path to the default Java installation as well as all alternative ones present. The best generic way to find this out is to run /usr/libexec/java_home The location has changed from Java 6 (provided by Apple) to Java 7 and onwards (provided by Oracle). ![]()
