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

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:\
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T01:09:06+05:30)
Maven home: C:\Program Files\apache-maven-3.5.0\bin\..
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_131\jre
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.

In my case, i had overridden the JAVA_HOME variable in the mvn.cmd a long time ago and forgotten about it. So there is one more place to check if the other solutions aren't working.

The override looks like this:

set JAVA_HOME=C:\YourJDK\jdk_xx

Linux Users

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.

also, sometimes it might cause some problems if the java_home variable is not included in the user variables for administrators' section. So also add them there if you are logged into the administrators account.

as you know, java home var should not have the bin part while the path should point to the bin.

You can set JAVA HOME by following commands in CMD

setx JAVA_HOME "C:\Program Files\Java\jdk-11.0.17"
setx PATH "%PATH%;%JAVA_HOME%\bin";

Make sure to close all CMD instances and then open them again to check.

Your JAVA_HOME needs to be set where the jdk is present C:\Program Files\Java\jdk-11.0.13 In the path you could use %JAVA_HOME%/bin

PS : Also check if you are pointing to the right version of jdk in your environment variables. In my case I had jdk-11.0.13 but had outdated path in the env variable which was still pointing to C:\Program Files\Java\jdk1.8.0_301.

if you are using mac...

  1. install JDK

  2. config JAVA_HOME by vim ~/.bash_profile like this, change the jdk file path to your own

    JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_333.jdk/Contents/Home PATH=$PATH:$JAVA_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME PATH CLASSPATH

  3. source ~/.bash_profile and then check by java -version and mvn install

  4. if it does not work, restart your computer and check again.

i solved this problem by restarting my computer...

In your environment variable path, add this

%JAVA_HOME%\bin

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!)

Last step: important Restart IntelliJ or another program you are using.

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
fi

You need to have the full path to the JDK folder. IF you use links like ~ in your path replace it with /home/<your_user>/, or it will give this error.

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.

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.

Following steps solved the issue for me..

  • Copied the zip file into the Program Files folder and extracted to "apache-maven-3.6.3-bin".

  • Then copied the path, C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3

  • Then created the new MAVEN_HOME variable within environmental variables with the above path.

Also added,

C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3\bin

address to the "PATH" variable

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 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.

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

In case of windows if there is any space in path to jdk like ("C:\Program Files\jdk") then it doesn't work, but if we keep jdk in a location which doesn't have space then it works fine like ("C:\jdk")

Setting JAVA_HOME directory from command line worked for me!

First:

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

Or :

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

Then try:

mvn -version

to make sure you do not get the same error. :)

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 .

I had the same problem on Windows 7.

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

The solution turned out to be very simple - right click on command prompt shortcut and choose "Run as Administrator". After that, the problem disappeared)

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
Java version: 1.7.0_05, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.8.2", arch: "x86_64", family: "mac"
