在进行 docker-compose build 时遇到 Build 失败问题？

Question

FROM java:8
FROM maven:alpine

WORKDIR /app
COPY pom.xml /app
RUN mvn clean
RUN mvn compile
RUN mvn install

COPY . /app
RUN mvn clean install
ENTRYPOINT ["java", "-jar", "/target/Brabo-Asset-Service-Web-0.0.1-SNAPSHOT-spring-boot.jar"]

Getting this error:

I would agree with @stefano in regards to looking into doing a multistage build, but essentially your specific is issue is due to the fact that you are running a maven build without including/copying your source code first, so I believe your Dockerfile should look something like so:

FROM maven:alpine

WORKDIR /app
COPY . /app
RUN mvn clean install
ENTRYPOINT ["java", "-jar", "/target/Brabo-Asset-Service-Web-0.0.1-SNAPSHOT-spring-boot.jar"]
