Profile not found. Tried ~/.bashrc, ~/.bash_profile, ~/.zshrc, and ~/.profile.

Error when installing NPM

 Profile not found. Tried ~/.bashrc, ~/.bash_profile, ~/.zshrc, and ~/.profile.



Fix:
Run command and try again
touch ~/.bash_profile 


Reason

https://github.com/nvm-sh/nvm/issues/1837

your system may not have a [.bash_profile file] where the command is set up. Simply create one with touch ~/.bash_profile and run the install script again
you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry."

Error when building the Jenkins pipeline  (Pipeline project style)

Error snippet:
+ mvn clean package
/var/jenkins_home/workspace/atmosphere pipeline/spring-boot-samples/spring-boot-sample-atmosphere@tmp/durable-7c163949/script.sh: 1: /var/jenkins_home/workspace/atmosphere pipeline/spring-boot-samples/spring-boot-sample-atmosphere@tmp/durable-7c163949/script.sh: mvn: not found

http://phase2.github.io/devtools/common-tasks/ssh-into-a-container/


 In summary, use below commands as specified in article

  • Use docker ps to get the name of the existing container
  • Use the command docker exec -it {containername} /bin/bash to get a bash shell in the container
  • Generically, use docker exec -it {containername} {command} to execute whatever command you specify in the container.

running docker as root user 
docker exec -it --user root {container id} /bin/bash

Cannot run program "mvn" (in directory : error=2, No such file or directory

Note : In below scenario jenkins was deployed in Linux container

Scenario:  Jenkins build failed with error.

  • Go to Global Tool Configuration (http://localhost:xxxx/configureTools/) or navigate Jenkins Home Page - > Manage Jenkins - > Global Tool Configuration
  • Scroll down and make the below configuration under Maven Section
  • Click Save
