问题
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
built with docker build . -t rest-notes results in the following error:
Exception in thread "main" javax.net.ssl.SSLException: java.security.ProviderException: java.security.InvalidKeyException: EC parameters error.
What can I do in the Dockerfile to avoid this and make the Gradle wrapper work?

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

Upgrading to a later Maven docker image solved the problem for me. I replaced maven:3-jdk-7 with maven:3.6-jdk-11.
In my case, I had used an older sample GitLab CI script. My updated GitLab CI script now looks like:
image: maven:3.6-jdk-11
build:
script: "mvn install -B"
