Maven environment variable not defined - maven

A friend asked me to make a minecraft plugin for them, so I need to install Maven. I've installed the following user variables as instructed by the tutorial.
JAVA_HOME -- Value: C:\Program Files\Java\jdk1.8.0\bin
M2_HOME -- Value: C:\Minecraft Plugin Development\apache-maven-3.2.1
M2 -- Value: %M2_HOME%\bin
I've also added ;%M2% to my system PATH variable as instructed. My problem is running the mvn --version command to verify if it's installed. I tried to also set the variables using SET M2, SET M2_HOME, SET JAVA_HOME, and SET PATH. I've attempted that as instructed by an answer on
windows 7 maven 2 install
It responds to me when I try setting it in Command Propmpt by saying Environment variable (Name) not defined. How would I successfully run mvn --version?
Thanks for reading.
.
EDIT in response:
So I went to the bin directory like jayalalk said, I ran it and it recognized the command. However, it said
Error: JAVA_HOME not found in your environment.
Please set the JAVA_HOME variable in your environment to match the location of your java
installation.
I checked and I have declared JAVA_HOME in both User and System variables to the correct location of my java installation, C:\Program Files\Java\jdk1.8.0\bin.
Also, this is my system PATH variable value: C:\Program Files\Java\jdk1.8.0\bin;%M2% Is there anything wrong with that?

It seems set JAVA_HOME = "C:\Program Files\Java\jdk1.8.0" and path = %JAVA_HOME%\bin;%M2%.

JMETER_HOME environment variable is not defined

I tried to execute JMeter 4.0 from the command prompt in Windows 7.
I got the following error during execution:
The JMETER_HOME environment variable is not defined correctly This
environment variable is needed to run this program
I set C:\apache-jmeter-4.0\bin to JMETER_HOME variable, but the problem remains
I can start JMeter with its jar file.
I use jdk1.8.0_162 and set JAVA_HOME environment variable correctly.
You should set JMETER_HOME to main JMeter directory as C:\apache-jmeter-4.0
Also don't set JMeter directory to JAVA_HOME variable (should hold Java installation path)
Ensure you have installed Java and JMETER Gui works fine first.
Then,
At User Variables add JMETER_HOME followed by D:\Jmeter (Where Jmeter is installed)
Next select Path in User variables and add D:\Jmeter\bin(Where Jmeter bin path is)
Save and restart cmd.
P.S: This is for Windows solution
First ensure you've Java installed
Second you need to ensure the working directory of your call is the JMeter installation directory.
Assumption your JMeter installation is located under:
C:\Program Files (x86)\apache-jmeter-4.0
then you need to set this as working directory.
As you can read in the jmeter.bat file itself:
JMETER_HOME - installation directory. Will be guessed from location of jmeter.bat
This might sound obvious, but I'm getting this error on machines that don't have Java installed. Of course, though a better message might have been nice!
Easiest way:
just delete the JMETER_HOME environment variable, run jmeter.bat and variable will be added automatically.
Asually a wrong JMETER_HOME entry causes this. make sure you have JMETER_HOME pointed to jmeter folder not inside bin directory. For example ,from my local windows i am able to see this thie environment variable
Type : echo %JMETER_HOME%
For me, setting the Windows environment variable didn't help. Instead it worked when I set the variable at the command line (using the root folder of jmeter).
Like this:
SET JMETER_HOME=C:\apache-jmeter-4.0
ensure java is installed and can check with java —version
assuming the path jmeter installed is C:\apache-jmeter-5.3
add the user variable
press new
add Jmeter variable name as JMETER_HOME
variable value as: C:\apache-jmeter-5.3
add the path
look for Path system variable and press edit
edit it to have C:\apache-jmeter-5.3\bin
it doesnt have Path(very unlikely), than press new and add variable name as path and value as C:\apache-jmeter-5.3\bin
restart cmd and type jmeter should do the job.
One reason for getting this error is to have JMETER_HOME variable defined in the environment variables but pointing to the wrong location. I had this problem due to previous installation.
You don't need to set JMETER_HOME path explicitly under user variables, just add/change under system variables under path variable as your bin path. If you already have earlier version of JMeter just append with latest version. Path looks like : C:\XXX\apache-jmeter-4.0\bin

Windows7 run elasticsearch.bat Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME

enter image description here
I want to use elasticsearch on Windows64. At first my Java version is not the same as the Java_Home.Then I reinstalled JAVA. And I found a solution said that the system will find JAVA under C:\ProgramData\Oracle\Java\javapath , So I replaced the latest java.exe javaw.exe , javaws.exe there, but the problem still exists.
I found below code in C:\elasticsearch-5.2.1\bin\elasticsearch could I do any changes to this to fix this problem?
enter image description here
Have you tried following?
Check your Environment variables for "JAVA_HOME" and "Path" inside system variables.
The location for JAVA_HOME is your the location of your jdk
For Path variable you should add new "...\Oracle\Java\javapath"
Add C:\ProgramData\Oracle\Java\javapath; to Path variable in Environment variable.
And Remove JAVA_HOME, as you have already Java Path to Path, you don't need to mention it twice.
It will surely help

mvn command is not recognized as an internal or external command

I am getting the mvn command not recognized as an internal or external command.
I have setup the M2_HOME, JAVA_HOME and added %M2_HOME%/bin to the path variable. All are system variables. Still getting the same problem.
Echoing the variables showing me the correct paths.
Path to Maven: C:\apache-maven-3.1.0\apache-maven-3.1.0
M2_HOME:C:\apache-maven-3.1.0\apache-maven-3.1.0
PATH: Other things,C:\Program Files (x86)\Java\jdk1.7.0_40\bin,C:\apache-maven-3.1.0\apache-maven-3.1.0\bin
and I have restarted my computer twice.
Right click on My Computer >> Properties >> Advanced system settings >>
System Properties window will get displayed
Under Advanced >> Environment Variables
Click on New to set Environment Variables
Variable name: JAVA_HOME
Variable value: C:\Program Files\Java\jdk1.8.0_121
Variable name: M2
Variable value: %M2_HOME%\bin
Variable name: M2_HOME
Variable value: C:\Program Files\Apache Software Foundation\apache-maven-3.5.0
Variable name: Path
Variable value: %M2_HOME%\bin
Then click on Ok, ok, ok.
Now restart you command prompt and check again with “mvn –version” to verify the mvn is running, you may restart your system also.
It should be working now.
Restart your machine, after setting up your M2_HOME (pointing to you Maven basedir, NOT the bin dir) and PATH (PATH=%M2_HOME%\bin;%PATH%).
Then do:
dir %M2_HOME%\bin\mvn*
If there is a .bat file, it should work under Windows, as it appears to be finding it. If there isn't one, then your paths are not right and you need to make sure your %PATH% variable really points to the correct path to Maven.
Make sure you are using the proper slashes for your OS. Under Windows they're \.
Write the entire maven path into the Environment PATH variable.
Example:
C:\Program Files\apache-maven-3.2.3\bin;
My PATH variable wasn't reading %M2% or %M2_HOME%\bin properly, and therefore I wrote the full path into the PATH variable.
Working.
This is worked for me:
1-download apache-maven-3.3.9-bin.tar.gz file from https://maven.apache.org/download.cgi
2-copy the folder under c:\programfiles
3-set variables as this:
M2_HOME ----- C:\Program Files\apache-maven-3.3.9
M2 ----- C:\Program Files\apache-maven-3.3.9
add Path variable to this: ;C:\Program Files\apache-maven-3.3.9\bin
then run the cmd as system admin
it worked.
I also was facing with the same issue still after adding path in environment variable and running it as a normal user in command prompt.
Then I opened command prompt and tried running as "Run as Administrator" and I was able to download all the packages with respect to the project.
Are you trying to reference a user variable in system variables? Try echo %path% and the M2 should have been fully expanded to show the file path to your Maven directory. If it hasn't, then that's the problem.
To fix it, you should create a user variable called PATH and add your %M2% reference into there.
Open Command prompt As "Run As a administrator" and try.
I have a stupid comment but someone else will have that issue. I was getting that same error when I was trying to put in ./mvnw clean package and I found out that I had to change it a bit to .\mvnw clean packageand I lived happily ever after.
Windows 10 -
Add new variable "M2_HOME" -
Update variable "path" -
Verify on cmd -
Try %M2_HOME%\bin (\ rather than /)
I faced this problem which kept me busy and buggy for quiet sometime. I was facing the problem (mvn not recognized) after setting up all required environment variables absolutely correctly. So by going by one of the response here, I switched to another version of maven and that fixed the problem.
Not being completely convinced why it worked this way, I then unzipped the problematic-version and updated env-vars which made it work.
The problem was when I initially extracted file from the zip, I modified the directory structure a bit. When you extract the zip, say apache-maven-X.x.x-bin.zip, it creates the folder structure as - "apache-maven-3.5.0-bin\apache-maven-3.5.0..."
In my first attempt I had modified this structure by deleting apache-maven-3.5.0-bin folder and bringing apache-maven-3.5.0 structure one folder up. This was causing the problem.
Try with echo %path% , if this option doesn't show your M2_HOME and others variable values as directory path, then create a new environment variable lets say PATH, and assign like below:
PATH=%JAVA_HOME%\bin;%M2_HOME%\bin
Add this in variable path=.....;%PATH%
Now open a new cmd, and try to echo %path%
it will show all thh system path
Now you can check mvn -version it will solve the problem , if not try to restart the system
P.S. as per doc, you should expend your zip distribution in C:\Program Files\Apache Software Foundation. But ideally it doen't matter
I'm using Maven 3+ version. In my case everything was fine. But while adding the M2_HOME along with bin directory, I missed the '\' at the end.
Previously it was like: %M2_HOME%\bin , which was throwing the mvn not recognizable error.
After adding "\" at the end, mvn started working fine. I guess "\" acts as pointer to next folder.
"%M2_HOME%\bin\" Should work, if you missed it.
Try setting the path of maven first through command prompt.
setpath.bat Open the cmd from the base window of the batch file.
The rest maven commands can be used once path is set through cmd.
One most important and often overlooked aspect is the %MAVEN_HOME%\bin or %M2_HOME%\bin should be the first thing in the %PATH% environment variable.
If you've already set the JAVA_HOME and M2_HOME (or MAVEN_HOME in my case) environment variables and added the \bin folder to the Path environment variable and still not working, then this solution could be for you.
Make sure that you have set your variables in the right order, your %JAVA_HOME%\bin folder should be added before the %MAVEN_HOME%\bin just like the shown image
I tried all way finally below step solved the issue .
In the downloaded zip there is file README , in that its mention that
for windows
set PATH="c:\program files\apache-maven-3.x.y\bin";%PATH%
create new PATH variable and assign first maven then %PATH%
it worked out for me .
Try It once
In your Environement variable :
new system variable:
M2_HOME Your mvn directroy "C:\......\bin"
new user variable:
M2 %M2_HOME%
edit the CLASSPATH by adding %M2%
finally open the cmd and write
path=%CLASSPATH%
enjoy
I had this same error but my problem was I had the following:
M2_HOME = C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;
Which meant my PATH = %M2_HOME%\bin; (etc)
...became C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;\bin
i.e. a semicolon was where it shouldn't be.
Which I discovered because Michael Ferry suggested using 'ECHO %PATH%' to see what the actual PATH output was.
I had the same problem. But just restarting my computer after setting up the Maven path resolved the issue.
Variable Name: M2_Home
Variable Value:C:\Apache\apache-maven-3.3.9
Variable Name: Path
Variable Value:C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;%JAVA_HOME%\bin\;%M2_HOME%\bin\
I faced similar problems. The article that helped me solve similar issues is by MKyong and is here: ****https://www.mkyong.com/maven/how-to-install-maven-in-windows/****
It is very important to include in maven's path the file that contains the 'bin','boot', 'conf', 'lib' etc. file folders. For example, in my case, the correct path is:
C:\Program Files\Apache Software Foundation\maven\apache-maven-3.5.0-bin\apache-maven-3.5.0
For me it was not working since I was editing Path variable in "User variable" and adding it under "System variable" made it work. Hope it helps.
For Windows you need to do the following:
Windows and type env
Open the edit environment panel
Click Environment Variables
In the system variables section, double click Path
In the dialog, create a System Variable under Path
like below ->
MVN_HOME: C:\Users<username>\Documents\Project\Software\apache-maven-3.6.3\bin
Open a new command prompt and hit mvn, you should be able to now.
I also faced the issue.
But the problem I faced was due to the location name where the maven was stored on system.
The path did contain spaces due to which system was not able to reach the path leading to this issue.
The issue got resolved for me when I moved the maven to a location which did not contain any spaces.
The existing answers are too complicated. I just fixed the same issue by
scoop install maven
That requires you install scoop the package manager for Windows in the first place.
However I recommend you install the scoop so that everything becomes easy.
Yeah so, for me, I fixed it by setting up the M2 variable.
MAVEN_HOME, JAVA_HOME and M2_HOME we set up with their paths, but the command, "mvn -verison" was still showing the error.
So I inserted one more variable, named, "M2" and then set the path of the maven folder (not the bin of the same) and ran the command in cmd.
It worked.
Adding environment variables from command prompt or windows powershell worked for me. I was able to verify the environment variables present using "set" command in command prompt.
You have written three paths above. The first path (path to maven) should be pointing to the bin directory.
Path to Maven: C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;
Below are right. Above path should be corrected.
M2_HOME:C:\apache-maven-3.1.0\apache-maven-3.1.0;
PATH: Other things,C:\Program Files (x86)\Java\jdk1.7.0_40\bin,C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;

Maven 3.0.5 installed in Windows 7 but not able to run through command prompt

As per suggestions given in this site i have added the required variables and values as below too but no response
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_25
M2=%M2_HOME%\bin
M2_HOME=C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin
PATH=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;%M2_Home%\bin
Please help me
Your path configuration has a M2_Home instead of M2_HOME. It should be all uppercase
%M2_HOME%
Also notice, you are specifying bin twice, should
M2_HOME=C:\Program Files\apache-maven-3.0.5-bin\apache-maven-3.0.5
I had same situation multiple times, i.e. configured M2_HOME as user env variable and added it to PATH (system env variable), i.e.
PATH=%M2_HOME%\bin; ...
However sometimes (randomly) Windows don't resolve variable in path, run "echo %PATH%" in your console. In my case I can still see %M2_HOME% there instead of resolved path to maven installation directory. It seems to be a bug in Windows itself, which is present in WinXP and Win7 at least.
I have resolved it as follows:
Open env variables, change M2_HOME (user one) to correct value. Press OK to save and close window
Open env variables again, now open PATH (system one) variable details, make sure M2_HOME is there and press OK, i.e. just save without any modification.
Now, open command line and check "echo %PATH%" - there should be resolved path. Confirm by running "mvn --version".
I know it really sounds like a black magic, but it should work...

JAVA_HOME variable is not recognized in Win 7 Pro 32 bit

I have set JAVA_HOME system variable to C:\Program Files\Java\jdk1.6.0_30 and added %JAVA_HOME%\bin to Path variable.
When I check list of variables using new session of cmd I cannot see JAVA_HOME variable on the list at all, however Path variable contains record C:\Program Files\Java\jdk1.6.0_30\bin.
When I want to run mvn I get:
ERROR: JAVA_HOME not found in your environment.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation
I double checked configuration, restarted the machine and the problem persists.
Can you please advise? It looks like the variables are set, but JAVA_HOME does not make it to the list of variables, however value which derives from it makes it to the Path variable
