This is Docker compose:

version: '2'
services:
  master:
    build: .
    image: jenkins/jenkins:latest
    restart: unless-stopped
    hostname: jenkins
    ports:
      - "8080:8080"
      - "50000:50000"
    volumes:
      - jenkins_home:/var/jenkins_home
 
volumes:
  jenkins_home:

And this is my Docker file:

FROM jenkins/jenkins
 
USER SYSTEM
RUN apt-get -y update && apt-get install -y maven
 
USER jenkins
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

Anyone can help me? Thank you in advance.

User jenkins in your container does not have access to folder C:\Users\cpaez\Documents\Automation\MOM\JSFiles on your host. Given your docker-compose.yml it's probably caused by either:

• This directory does not exists in your container (as per the volume you are mounting), you may try to add

    volumes:
       - jenkins_home:/var/jenkins_home
       - /c/Users/cpaez/Documents/Automation/MOM/JSFiles:/c/Users/cpaez/Documents/Automation/MOM/JSFiles
      

• Ensure this folder has enough permission for jenkins user in your container to write this directory (your container will run as this user as per the USER jenkins instruction)
