java - 在执行 docker-compose build 时遇到构建失败问题？

问题描述

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"]

收到此错误：

解决方案

关于考虑进行多阶段构建，我同意@stefano，但基本上您的具体问题是由于您正在运行 maven 构建而没有首先包含/复制您的源代码，所以我相信您的 Dockerfile 应该看起来像这样：

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"]
