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. 8 ) Enter JDKHOME as Variable name, enter the jdk installation path, in my case C:Program Files (x86)Javajdk1.7.025, this might be different in your case. 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. So ask for the location of javac and then use dirname twice. Alas, cabal only supports one location for both kinds of build, and so it is set to be the later.
Default installation path for jdk on mac mac os x#
For user installs, since /bin is not on the PATH by default on Mac OS X and may not exist, binaries are symlinkd into: /Library/Haskell/bin. 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 but what we need is the path to the directory containing bin of the JDK. For global installs, the logical place is one of: /usr/bin /usr/local/bin. If that gives you something like /usr/bin/java, which is a symbolic link to the real location, run ls -l `which java` ), 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: 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.
First, all environment variable settings are saved in the current user’s.
Default installation path for jdk on mac how to#
Do not worry, this article will tell you how to do it in macOS.
This is the natively supported way to find out both the path to the default Java installation as well as all alternative ones present. On macOS set javahome, mavenhome is not as easy as in windows after you install JDK or maven. 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).
