JAVA_HOME Variable Issues

Question

I've seen the numerous other posts on here regarding JAVA_HOME variables and I have tried them all.

When I try and execute any gradle related tasks from the terminal I receive the following error:

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_191

Please set the JAVA_HOME variable in your environment to match the location of your Java Installation.

If I run WHERE java I get C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe and c:\jdk\bin\java.exe, which leads me to believe there's an issue somewhere with this.

I added C:\Program Files\Java\jdk1.8.0_191 to my path and added JAVA_HOME as a system variable pointing at C:\Program Files\Java\jdk1.8.0_191. What am I missing? I have been banging my head against this for a while now; any help would be greatly appreciated.

EDIT: I have confirmed that C:\Program Files\Java\jdk1.8.0_191 does in fact exist and the contents are

• bin
• include
• jre
• lib
• man
• COPYRIGHT
• javafx-src.zip
• LICENSE
• README
• release
• src.zip
• THIRDPARTYLICENSEREADME
• THIRDPARTYLICENSEREADME-JAVAFX

Answer 1

Change your path variable to include %JAVA_HOME%\bin

Remove quote from your JAVA_HOME, it should just be C:\Program Files\Java\jdk1.8.0_191

Answer 2

If you check your PATH variable you will probably find that this directory "C:\Program Files (x86)\Common Files\Oracle\Java\javapath" appears before your JAVA_HOME directory.

Try changing the order, for example:

Instead of:

C:\Program Files (x86)\Common Files\Oracle\Java\javapath;%JAVA_HOME%\bin

Make it like this:

%JAVA_HOME%\bin;C:\Program Files (x86)\Common Files\Oracle\Java\javapath

Answer 3

On linux you would do:

export JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64/jre"
not
export JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java"
