dockerfile - openjdk-8-jdk有未满足的依赖关系openjdk-8-jre和OpenJDK-8-JDK-无头

Question

下面是停靠文件：

ENV CA_CERTIFICATES_JAVA_VERSION 20140324

RUN set -x \
    && apt-get update \
    && apt-get install -y \
        openjdk-8-jdk="$JAVA_DEBIAN_VERSION" \
        ca-certificates-java="$CA_CERTIFICATES_JAVA_VERSION" \
    && rm -rf /var/lib/apt/lists/* \
    && [ "$JAVA_HOME" = "$(docker-java-home)" ]

这就产生了错误：

Step 16/26 : RUN set -x     && apt-get update   && apt-get install -y       openjdk-8-jdk="$JAVA_DEBIAN_VERSION"        ca-certificates-java="$CA_CERTIFICATES_JAVA_VERSION"    && rm -rf /var/lib/apt/lists/*  && [ "$JAVA_HOME" = "$(docker-java-home)" ]

如何解决这个依赖问题？

Answer 1

您无法解决这个问题，因为openjdk-8-jre-headless破坏了早于20160321的ca-certificates-java版本。

不过，我不认为你需要解决这个问题：

apt-get install -y -t jessie-backports openjdk-8-jdk

工作正常，产生的设置确实有一个/etc/ssl/certs/java/cacerts文件。
