How do I fix maven error The JAVA_HOME environment variable is not defined correctly?

Question

Issue:

I am getting the Maven error \"The JAVA_HOME environment variable is not defined correctly\" when I run through Inno setup batch execution. Howe

Answer 1

A very common mistake people make is that, when they set JAVA_HOME or JRE_HOME, they set the value to C:\Program Files\Java\jdk1.8.0_221\bin or similar.

Please note JAVA_HOME and JRE_HOME value should not contain \bin

Answer 2

It seems that Maven doesn't like the JAVA_HOME variable to have more than one value. In my case, the error was due to the presence of the additional path C:\Program Files\Java\jax-rs (the whole path was C:\Program Files\Java\jdk1.8.0_20;C:\Program Files\Java\jax-rs).

So I deleted the JAVA_HOME variable and re-created it again with the single value C:\Program Files\Java\jdk1.8.0_20.

Answer 3

Following is the best way to get of the issue , check following on classpath:

1. Make sure JAVA_HOME system variable must have till jdk e.g C:\Program Files\Java\jdk1.7.0_80 , don't append bin here.

2. Because MAVEN will look for jre which is under C:\Program Files\Java\jdk1.7.0_80

3. Set %JAVA_HOME%\bin in classpath .

Then try Maven version .

Hope it will help .

Answer 4

My JDK is installed at C:\Program Files\Java\jdk1.8.0_144\.
I had set JAVA_HOME= C:\Program Files\Java\jdk1.8.0_144\, and I was getting this error:

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

When I changed the JAVA_HOME to C:\Program Files\Java\jdk1.8.0_144\jre, the issue got fixed.
I am not sure how.

Answer 5

I have removed JAVA_HOME variable and kept only path and classpath variables by pointing them to jdk and jre respectively. It worked for me.

Answer 6

SET JAVA_HOME=C:\Program Files\Java\jdk1.8.0

worked fine for me.

Note - Don't put double quotes over the path as mentioned above. Otherwise when you run

mvn -version

it will give following error

Files\java\jdk1.8.0_201\jre""=="" was unexpected at this time.
