Maven/Docker: cache all dependencies

Question

I\'m trying to build/deploy a spring boot in a docker container.

FROM maven:3.5.3-jdk-8-slim AS build
COPY ./pom.xml /app/pom.xml
RUN cd /app
RUN mvn -f /app         


        

Answer 1

I finally find the solution by using go-offline-maven-plugin.

         
            de.qaware.maven
            go-offline-maven-plugin
            1.0.0
            
                
                    
                        org.apache.maven.surefire
                        surefire-junit4
                        2.20.1
                        PLUGIN
                    
                
            
        

And trying to get all dependencies using:

mvn de.qaware.maven:go-offline-maven-plugin:resolve-dependencies
