how to set environment variable for java on mac

There are many different ways that a given JAVAHOME error might be logged.

Such a scenario tends to trigger the following error messages.

If you know your way around the Windows operating system, you should be able to add the JAVAHOME environment variable to your configuration and have it point to the installation root of your JDK within minutes.

And, it also tells you its not pointing to the right place, which is helpful as well.

All you need to do to fix this error is edit the JAVAHOME variable and point it to the correct directory.

It cannot point to a sub-directory of the JDK, and it cannot point to a parent directory that contains the JDK.

It must point directly at the JDK installation directory itself.

If you encounter the JAVAHOME invalid directory error, make sure the name of the installation folder and the value of the variable match.

Thats the directory you use to configure the Windows PATH, but it is wrong, wrong, wrong when you set JAVAHOME.

If you point JAVAHOME at the bin directory, youll need to fix that.

If the JAVAHOME variable is set as javahome, JAVAHOME or JavaHome, a Unix, Linux or Ubuntu script will have a hard time finding it.

The same thing goes for the value attached to the JAVAHOME variable.

And when the JAVAHOME environment variable gets set, some people point it at the JRE installation folder and not the JDK installation folder.

If you do, ensure that the JAVAHOME variable is not pointing at the JRE.

If you already have programs that installed their own version of the JDK, those programs could have added a reference to that specific JDK in the Linux or Windows PATH setting.

Some programs will run Java using the programs availability through the PATH first, and JAVAHOME second.

First, check the Ubuntu or Windows PATH variable and look to see if any other JRE or JDK directory has been added to it.

You might be surprised to find out that IBM or Oracle has at some prior time performed an install without your knowledge.

If thats the case, remove the reference to it from the PATH, add your own JDKs bin directory in there, and restart any open command windows.
