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

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

         <plugin>
            <groupId>de.qaware.maven</groupId>
            <artifactId>go-offline-maven-plugin</artifactId>
            <version>1.0.0</version>
            <configuration>
                <dynamicDependencies>
                    <DynamicDependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit4</artifactId>
                        <version>2.20.1</version>
                        <repositoryType>PLUGIN</repositoryType>
                    </DynamicDependency>
                </dynamicDependencies>
            </configuration>
        </plugin>

And trying to get all dependencies using:

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