Question

我尝试在Docker镜像中安装OpenJDK9和Gradle 4.5.1。

这是我的Dockerfile：

FROM ubuntu:latest
MAINTAINER Hari Sekhon (https://www.linkedin.com/in/harisekhon)

LABEL Description="Java + Ubuntu (OpenJDK)"

ENV DEBIAN_FRONTEND noninteractive

ARG JAVA_VERSION=9
ARG JAVA_RELEASE=JDK

ENV JAVA_HOME=/usr

RUN bash -c ' \
    set -euxo pipefail && \
    apt-get update && \
    pkg="openjdk-$JAVA_VERSION"; \
    if [ "$JAVA_RELEASE" = "JDK" ]; then \
        pkg="$pkg-jdk-headless"; \
    else \
        pkg="$pkg-jre-headless"; \
    fi; \
    apt-get install -y --no-install-recommends "$pkg" && \
    apt-get clean'


CMD /bin/bash

#install Gradle
RUN wget -q https://services.gradle.org/distributions/gradle-4.5.1-bin.zip \
    && unzip gradle-4.5.1-bin.zip -d /opt \
    && rm gradle-4.5.1-bin.zip

# Set Gradle in the environment variables
ENV GRADLE_HOME /opt/gradle-4.5.1
ENV PATH $PATH:/opt/gradle-4.5.1/bin

我收到了一个错误：

ubuntu@automation-ubuntu-17:~/dockerFiles$ The command '/bin/sh -c bash -c ' set -euxo pipefail && apt-get update && pkg="openjdk-$JAVA_VERSION"; if [ "$JAVA_RELEASE" = "JDK" ]; then pkg="$pkg-jdk-headless"; else pkg="$pkg-jre-headless"; fi; apt-get install -y --no-install-recommends "$pkg" && apt-get clean'' returned a non-zero code: 100

ubuntu:latest标记目前为ubuntu:18.04（仿生），仅包含java packages和openjdk-8-jdk-headless的openjdk-11-jdk-headless，但不包含openjdk-9-jdk-无头（已经达到end-of-life，至少是为了公开更新）。

openjdk-9-jdk-headless可在ubuntu:16.04（xenial）中找到。

我通过切换到ubuntu:16.04并将wget和unzip添加到要安装的软件包列表中来构建工作，因为它们随后用于下载和解压缩gradle但是默认情况下未安装。
