I want to do some programming with the latest JavaFX, which requires Java 8. I'm using IntelliJ 13 CE and Mac OS X 9 Mavericks. I ran Oracle's Java 8 installer, and the files look like they ended up at
/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk
but previous versions are at
/System/Library/Java/JavaFrameworks/jdk1.6....
Not sure why the latest installer puts this in /Library
instead of /System/Library
(nor what the difference is). But /usr/libexec/java_home
doesn't find 1.8, so all the posts I've found on how to set your current java version don't work. I've tried adding a symbolic link to make it look like 1.8 is in the /System/Library...
path, but it doesn't help. /usr/libexec/java_home -V
still only lists the old Java 1.6.
Ironically, the "Java" control panel under System Preferences shows only Java 1.8!
Why doesn't Oracle's installer put it where it really goes? And how can I work around this problem?
In macOS, the JDK installation path is /Library/Java/JavaVirtualMachines/jdk-10. jdk/Contents/Home . The root directory of the JDK software installation.
Type terminal in the search bar and open it by clicking on the icon in the search results. 3. Once in the command line, run the command: java -version . The output should display the Java version installed on your MacOS.
Oracle has a poor record for making it easy to install and configure Java, but using Homebrew, the latest OpenJDK (Java 14) can be installed with:
brew install --cask adoptopenjdk8
For the many use cases depending on an older version (commonly Java 8), the AdoptOpenJDK project makes it possible with an extra step.
brew tap adoptopenjdk/openjdk brew install --cask adoptopenjdk8
Existing users of Homebrew may encounter Error: Cask adoptopenjdk8 exists in multiple taps
due to prior workarounds with different instructions. This can be solved by fully specifying the location with brew install --cask adoptopenjdk/openjdk/adoptopenjdk8
.
