[maven] 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:\

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.

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)

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.

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)

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.

I was able to solve this problem with these steps:

1. Uninstall JDK java
2. Reinstall java, download JDK installer
3. Add/Update the JAVA_HOME variable to JDK install folder

I was having this same issue while my JAVA_HOME system variable was pointing to C:\Program Files\Java\jdk1.8.0_171\bin and my PATH entry consisted of just %JAVA_HOME%.

I changed my JAVA_HOME variable to exclude the bin folder (C:\Program Files\Java\jdk1.8.0_171), and added the bin folder to the system PATH variable: %JAVA_HOME%\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"

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.

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

1. create folder Maven inside this folder extract download file

2. this file should C:\Program Files\YourFolderName must in C:\Program Files drive

3. goto This PC -> right click -> properties -> advanced system -> environment variable

4. user variable ----> new & ** note create two variable ** if not may be give error i) variable name = MAVEN variable value = C:\Program Files\MAVEN

   ii) variable name = MAVEN_HOME variable value = C:\Program Files\MAVEN\apache-maven-3.6.3\apache-maven-3.6.3

5. system variable path ---> Edit---> new----give path of this folder i) C:\Program Files\MAVEN
   ii) C:\Program Files\MAVEN\apache-maven-3.6.3\bin

Hurrraaaaayyyyy

I was facing the same issue while using mvn clean package command in Windows OS

C:\eclipse_workspace\my-sparkapp>mvn clean package
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

I resolved this issue by deleting JAVA_HOME environment variables from User Variables / System Variables then restart the laptop, then set JAVA_HOME environment variable again.

Hope it will help you.

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

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.

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. :)

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.

removing JAVA_HOME and JAVA_JRE from environment variable is resolved the issue.

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 .

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")
