Last years it becomes more and more common to work in different projects running on different versions of Java. There still some running on Java 6, and there are tons already running on Java 8.
What isn’t nice is to change
PATH every time you work on
JVM aims to help you with that.
It’s basically a shell script that you load on your
will then listen on folder change events. If you
cd to a project running
on Java 7, and you have Java 8 on your
PATH, JVM will do the ~magic~ for you.
But how it works?
Basically, JVM will search for
pom.xml files. If any is found, search for a
java.version property in it. If it’s found, search for matching installed
Java, otherwise, JVM will look for
.java-version file, and, if found, try
to set a matching Java version to your
PATH, otherwise do nothing.
Currently, it works Mac OS X and Ubuntu only, but, of course, pull requests are welcome.
