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. However, I am able to run successfully outside Inno Setup.(e.g Command line, Batch file, Vbs). I am clueless to identify the issue.

Inno Setup Invoked Prompt:

C:\>mvn -version
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

Regular Command Prompt:

C:\>mvn -version
C:\

Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"

Maven Command from InnoSetup:

[Files]
Source: "C:\@Setup\MavenInstaller.bat"; DestDir: "{tmp}"; Flags: ignoreversion
[Run]
Filename: "{cmd}"; Parameters: "/C ""{tmp}\MavenInstaller.bat"""

Maven Command from Batch File:

mvn archetype:generate -DgroupId=com.mycompany.mycomponent-DartifactId=%APPLICATION_NAME% -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

Setting JAVA_HOME

Check the If Java 1.8 is installed or not. If not installed, Install the same and set the JAVA HOME as follows.

SETX JAVA_HOME "C:\Program Files\Java\jdk1.8.0_131"
SETX -m JAVA_HOME "C:\Program Files\Java\jdk1.8.0_131"
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v Path /t REG_SZ /d "%path%;C:\Program Files\Java\jdk1.8.0_131\bin;" /f

Many Thanks.

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

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.
Because MAVEN will look for jre which is under C:\Program Files\Java\jdk1.7.0_80
Set %JAVA_HOME%\bin in classpath .

Then try Maven version .

Hope it will help .

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 is work, thank you. But how can this work using directory `jre` instead `bin`? – NM Naufaldo Jun 06 '20 at 09:17
You might need to restart the bash/cmd for it to reflect changes. – Vibhor Dube Aug 09 '20 at 05:59
This has worked for me as well. Since I installed the JDK via IntelliJ IDEA it saved it on `%HOMEPATH%\.jdks` so my path that I had to add to the environment variables ended up being `%HOMEPATH%\.jdks\corretto-1.8.0_322\jre`. Thanks : ) – badjuice Mar 29 '22 at 13:13

This is how I fixed this issue on Windows 10:

My JDK is located in C:\Program Files\Java\jdk-11.0.2 and the problem I had was the space in Program Files. If I set JAVA_HOME using set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2" then Maven had an issue with the double quotes:

C:\Users>set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2"

C:\Users>echo %JAVA_HOME%
"C:\Program Files\Java\jdk-11.0.2"

C:\Users>mvn -version
Files\Java\jdk-11.0.2""=="" was unexpected at this time.

Referring to Program Files as PROGRA~1 didn't help either. The solution is using the PROGRAMFILES variable inside of JAVA_HOME:

C:\Users>echo %PROGRAMFILES%
C:\Program Files

C:\Program Files>set JAVA_HOME=%PROGRAMFILES%\Java\jdk-11.0.2

C:\Program Files>echo %JAVA_HOME%
C:\Program Files\Java\jdk-11.0.2

C:\Program Files>mvn -version
Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T17:06:16+02:00)

It works on a single project once the values are set inside it's directory. How do I make it work everywhere? — Upulie Han, Jul 24 '22 at 13:07

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

The SETX command does not modify the current environment.

If you run the following batch file:

setx AAA aaa
echo AAA=%AAA%

It will print

AAA=

So your batch file is wrong. You have to use set:

set AAA=aaa

See What is the difference between SETX and SET in environment variables in Windows.

Setting JAVA_HOME directory from command line worked for me!

First:

Or :

export JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Then try:

In your environment variable path, add this

and also add your path of Maven folder like this

C:\Program Files (x86)\apache-maven-3.8.4\bin

Then create user variable named

JAVA_HOME

and set as path

C:\Program Files\Java\jdk-17\

(wihout bin!)

I struggled with the same issue, and the following worked for me.

Step 1: Check your JAVA_HOME setting. It may look something like:

JAVA_HOME="/usr/libexec/java_home"

Step 2: Update JAVA_HOME like so:

$ vim .bash_profile 

export JAVA_HOME=$(/usr/libexec/java_home)

$ source .bash_profile

Step 3: In a new shell, check that the Maven command is now working properly:

$ mvn -version

If this fixed the problem, you should get back a response like:

Apache Maven 3.0.3 (r1075438; 2011-03-01 01:31:09+0800)
Maven home: /usr/share/maven

OS name: "mac os x", version: "10.8.2", arch: "x86_64", family: "mac"

I have this: `export JAVA_HOME=$(/usr/libexec/java_home)` but still get the error. — Dr.jacky, Oct 23 '22 at 09:41

when you setup the java home variable try to target path till JDK instead of java. setup path like: C:\Program Files\Java\jdk1.8.0_231

if you make path like C:\Program Files\Java it will run java but it will not run maven.

Easy Win10 solution After JDK installation, download maven and paste to C:/, then copy its path and paste to "environment variables". Go to "windows key" on keyboard an type "environment variables". Click button "environment variables" on right-bottom corner.

From "system variables" choose JAVA_HOME and click "edit" Probably you have path to Java JRE instead of JDK. Check where you install JDK (in my case C:\Program Files\Java\jdk-17 ) and paste that path.

REMEMBER!! JDK path should not be path to bin folder because you will get double bin like C:\Program Files\Java\jdk-17\bin\bin\java because Maven check (see else condidion) :

if [ -z "$JAVA_HOME" ] ; then
    JAVACMD=`which java`
else
    JAVACMD="$JAVA_HOME/bin/java"
fi
 
if [ ! -x "$JAVACMD" ] ; then
    echo "The JAVA_HOME environment variable is not defined correctly" >&2
    echo "This environment variable is needed to run this program" >&2
    echo "NB: JAVA_HOME should point to a JDK not a JRE" >&2
    exit 1

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.

For Linux users, export the path to the base of the installation directory of your JDK.

For example

export PATH=/data/gadgets/opt/java/openjdk/current/bin/:$PATH

Please note that this is not the typical location on most Linux systems. However, you can find the location by searching for javac:

find / -type f -name 'javac' 2>/dev/null

which will print a list of filenames matching javac. There will likely be only one, but there can be more than one if you have multiple JDKs installed.
