Docker Could not build image from Maven-CodePudding

I need your help I got project to do and I don't know how to start it ,I hope do you are can help me .

and this repository: https://github.com/spring-guides/top-spring-boot-docker

First thing I built a Dockerfile According to README, I make Dockefile from repository to my host

FROM openjdk:8-jdk-alpine as build
WORKDIR /workspace/app

COPY mvnw .
COPY .mvn .mvn
COPY pom.xml .
COPY src src
RUN --mount=type=cache,target=/root/.m2 ./mvnw install -DskipTests

ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} target/application.jar
RUN java -Djarmode=layertools -jar target/application.jar extract --destination target/extracted

FROM openjdk:8-jdk-alpine
RUN addgroup -S demo && adduser -S demo -G demo
VOLUME /tmp
USER demo
ARG EXTRACTED=/workspace/app/target/extracted
WORKDIR application
COPY --from=build ${EXTRACTED}/dependencies/ ./
COPY --from=build ${EXTRACTED}/spring-boot-loader/ ./
COPY --from=build ${EXTRACTED}/snapshot-dependencies/ ./
COPY --from=build ${EXTRACTED}/application/ ./
ENTRYPOINT ["java","-noverify","-XX:TieredStopAtLevel=1","-Dspring.main.lazy-initialization=true","org.springframework.boot.loader.JarLauncher"]

After I build the Dockerfile

C:\Users\LS\Desktop\Job\Test>docker build -t myorg/myapp .

Please look more at line, you could provide a correct jdk version.

CodePudding user response：

The javac in the docker image is too Old to be able to compile Java 17 code

Either convert to java 8 or use a java17-based image.
