Dockerfile中的Maven生命周期
首先感谢您的时间。 我试图在dockerfile中运行maven命令：
# Base container contains maven, jdk on ubuntu FROM maven:3-jdk-8 # copy my build config pom file to container ADD pom.xml /app/ # copy the source file directory to the container ADD src/ /app/src/ # move the app directory inside container to perform mvn buill WORKDIR /app/ RUN ["mvn", "dependency:resolve"] RUN ["mvn", "verify"] # resolve dependency offline as suggested by Nicolas #RUN mvn dependency:go-offline # build by using maven RUN mvn package 但我有代理问题：

我想我必须添加settings.xml，但我不知道是否必须添加在我的项目或另一个目录的根目录。
问候！
您没有发布确切的代理问题，但无论如何，您可能必须将自定义的settings.xml文件（ ADD settings.xml /app/ ） ADD settings.xml /app/到Maven（ RUN mvn -s settings.xml package ）。
如果它~/.m2/调用，我build议把settings.xml为~/.m2/这样每个Maven调用都会默认使用它。
这是您正在尝试构build的唯一应用程序吗？ 如果不是，我会build议build立两个图像如下：
- Maven构build图像：在〜/ .m2中包含java和maven以及您的设置xml。 该图像具有源代码的卷装，因此可以多次使用，例如在CI / CDpipe道中。
- 应用程序图像：此图像只有java才能运行应用程序，甚至可以在生产环境中运行容器。
HTH！
问题解决了，问题就是代理。
我不得不在docker文件中添加这一行
ADD settings.xml /root/.m2/settings.xml
谢谢 ！！
