在docker中安装maven

Question

我正在尝试在 Dockerfile 中使用 maven 安装和构建一个文件，但出现错误

 mvn not found

... 我参考了一些文章，但没有找到任何东西

任何人都可以帮我解释为什么我会遇到这个问题以及如何解决这个问题吗？

我的代码

# Setup JAVA_HOME -- useful for docker commandline
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/

#dwnl zip and move to /opt/files
RUN mkdir /opt/files
RUN  wget <this is my zip file> -O /tmp/zip_file.zip
RUN cp /tmp/zip_file.zip /opt/files/


ENV MAVEN_HOME /usr/share/maven
ENV MAVEN_CONFIG "$USER_HOME_DIR/.m2"

RUN mvn clean install -Pdevelopment
#RUN mvn clean install -Pdeployment 


CMD ["mvn", "--version"]

在构建时...

我看到基本目录是： 对于 maven 主目录 MAVEN_HOME /usr/share/maven 对于配置---> MAVEN_CONFIG "$USER_HOME_DIR/.m2 并且 user_home_dir 是根目录

提前致谢

这似乎是一个很好的解决方案：https://gist.github.com/LuanComputacao/6cf199fc577f7ee5fb85a504176d78ca。

他们使用 alpine，所以你必须稍微改变一下才能在 ubuntu 上使用它。
