locate-java-home v1.1.2
Locates
JAVA_HOME
on any platform, and can differentiate between different versions.
Usage
npm install locate-java-home
; // or var ImportJavaHome = require('locate-java-home').default;; // Limit to JDKs for Java 6 and above.;
Motivation
I originally wrote this utility for DoppioJVM, which requires access to the Java 8 JDK during build time.
I required the following:
- The ability to check the version of
java
inJAVA_HOME
. - Verify that
JAVA_HOME
is a JDK and not a JRE. - Detect a Java 8 JDK even if it is not the default version of Java installed.
- Have the above work across Windows, Mac, and Linux.
Since this functionality is likely generally useful, I have decided to release this as a standalone library! Enjoy! :)

Options

Global Script
If you install locate-java-home
globally, you'll have access to the locate-java-home
command
line tool. Currently, it lists all of the JAVA_HOME
locations on your system. If there's any
desire to expand it into a full-fledged command line tool that exposes the options of this
library, let me know!
