With the latest version of Docker for Mac and Windows (18.06), you can prefix all your mvn commands by RUN --mount=target=/root/.m2,type=cache:

Example:

# syntax = tonistiigi/dockerfile:runmount20180618
FROM maven:3.5-jdk-8-alpine AS build
COPY . .
RUN --mount=target=/root/.m2,type=cache mvn --batch-mode clean compile assembly:single

FROM openjdk:8-jre-alpine3.7
EXPOSE 8080
COPY --from=build target/app.jar /app.jar
CMD java -jar /app.jar

Usage:

$ DOCKER_BUILDKIT=1 docker build -t app .
