如何使用openjdk：7 Docker映像和Gradle包装器避免EC参数错误？ [英] How to avoid `EC parameters error` using the openjdk:7 Docker image and a Gradle wrapper?

问题描述

此Dockerfile：

This Dockerfile:

FROM openjdk:7

WORKDIR /restdocs/
RUN git clone https://github.com/spring-projects/spring-restdocs.git /restdocs
RUN git checkout v1.1.2.RELEASE

RUN ./gradlew build

使用 docker build构建。 -t rest-notes 导致以下错误：
线程主中的异常javax.net.ssl.SSLException：java.security.ProviderException：java。 security.InvalidKeyException：EC参数错误。

我该如何在Dockerfile中避免这种情况并使Gradle包装器工作？

What can I do in the Dockerfile to avoid this and make the Gradle wrapper work?

推荐答案

感谢Erich Seifert及其在这里的贡献，我得以解决这个问题： https://github.com/eseifert/gral/commit/c24e08a91952a99b8c8b686a1b172335db8cdf87 。更新的Dockerfile有效：

I was able to get around this thanks to Erich Seifert and his commit here: https://github.com/eseifert/gral/commit/c24e08a91952a99b8c8b686a1b172335db8cdf87. Updated Dockerfile that works:

FROM openjdk:7

RUN apt-get update && apt-get install sudo

# Fix the EC parameters error: (ref https://github.com/travis-ci/travis-ci/issues/8503)
RUN sudo wget "https://bouncycastle.org/download/bcprov-ext-jdk15on-158.jar" -O "${JAVA_HOME}"/jre/lib/ext/bcprov-ext-jdk15on-158.jar && \
  sudo perl -pi.bak -e 's/^(security\.provider\.)([0-9]+)/$1.($2+1)/ge' /etc/java-7-openjdk/security/java.security && \
  echo "security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider" | sudo tee -a /etc/java-7-openjdk/security/java.security

WORKDIR /restdocs/
RUN git clone https://github.com/spring-projects/spring-restdocs.git /restdocs
RUN git checkout v1.1.2.RELEASE

RUN ./gradlew build

（不要介意spring-restdocs分支的构建失败-与EC参数错误无关：）

(Never mind that the build of that spring-restdocs branch fails - that's not related to the EC parameters error:)
