使用本地 JDK 与 Maven 构建

要先下载 OpenJDK 和 Maven，与 Dockerfile 同级目录，分别命名为 jdk-21 和 mvn-3，目录结构：

• Dockerfile
• jdk-21/
• mvn-3/

FROM ubuntu:22.04

ENV DEBIAN_FRONTEND=noninteractive \
    TZ=Asia/Shanghai

RUN apt-get update && \
    apt-get install -y --no-install-recommends \
        locales \
        tzdata \
        ca-certificates \
        git && \
    rm -rf /var/lib/apt/lists/*

RUN locale-gen zh_CN.UTF-8 en_US.UTF-8

ENV LANG=zh_CN.UTF-8 \
    LANGUAGE=zh_CN:zh \
    LC_ALL=zh_CN.UTF-8

RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    dpkg-reconfigure -f noninteractive tzdata

WORKDIR /opt

COPY jdk-21 jdk21
COPY mvn-3 mvn

ENV JAVA_HOME=/opt/jdk21 \
    MAVEN_HOME=/opt/mvn \
    PATH="/opt/jdk21/bin:/opt/mvn/bin:${PATH}"

执行命令开始构建

docker build -t ubuntu-jdk-21 .
