mvn not found on $JENKINS_HOME/workspace/<projectname>@tmp

[banthita limwilai]

I've locally installed maven on both Master and Slave

and correctly set path for both JAVA_HOME and M2

jenkins@jenkins-slave-02:~$ echo $M2_HOME
/opt/maven
jenkins@jenkins-slave-02:~$ echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-amd64

Once reach the stage involved mvn command, the error occurs

/jenkins/workspace/simple_any_tests_master@tmp/durable-c32a56b1/script.sh: 1: mvn: not found

I notice that this @tmp dir was empty which means no pom.xml and when looking closely by reproduce the mvn compile in @tmp dir

I'm not sure what is the root cause of this error whereas incorrect maven path or slave setting (permission, etc.)

Any helps would be appreciated

Hi , 

Have tried to print the M2_HOME and JAVA_HOME in the pipeline you are trying to build . if they are empty it might be getting overwritten . try to put then as environment variables in jenkins config .

Personally I would switch to using maven wrapper as it have saved me
from a lot of issues like this.

But to your errors;

From your first error, check if mvn is on the path, so I would expect
to see "/opt/maven/bin" within the PATH assuming "/opt/maven" is where
maven is installed. Doesn't matter what M2_HOME or JAVA_HOME are until
mvn is on the path.

The second error implies you've not told maven what to do, as that
looks like a maven output. So it has managed to do "mvn" without any
arguments, so you need to do "mvn clean install" or "mvn verify".

For the existing Wrapper see https://github.com/takari/maven-wrapper
From the next Maven release see this wrapper
https://maven.apache.org/plugins/maven-wrapper-plugin/index.html

Hi :)

From the previous email, I asked for help about my Jenkins Slave unable to run mvn

I'd like to share what I've founded and the solution for the problem. 

I basically set the PATH for M2_HOME and MAVEN_HOME at /etc/profile which is somehow not work with the system's permission

So, I changed to set M2_HOME and MAVEN_HOME at /etc/environment instead and then the problem was gone :D

It's not Jenkins issue not even relate LOL but it's Linux 101

Anyway, amy thanks for Mallarapu Ananth and John for the suggestion. It was helpful

Cheers
