OpenJDK9（Docker）、graddle 4.2.1、GitLab

Question

私のプロジェクトはgraddlew 4.2.1を使用してローカルにビルドされています。しかし、GitLabにプッシュすると、以下のようなエラーが表示されます。 私はDockerを使用しなければならないので、これを動作させるためにDocker Imageが何を使用できるのか分かりません。はまた、これはgitlab-ci.ymlである：ここで

# This file is a template, and might need editing before it works on your project. 
# This template uses the java:8 docker image because there isn't any 
# official Gradle image at this moment 
# 
# This is the Gradle build system for JVM applications 
# https://gradle.org/ 
# https://github.com/gradle/gradle 
image: openjdk:9-jdk 

# Disable the Gradle daemon for Continuous Integration servers as correctness 
# is usually a priority over speed in CI environments. Using a fresh 
# runtime for each build is more reliable since the runtime is completely 
# isolated from any previous builds. 
variables: 
    GRADLE_OPTS: "-Dorg.gradle.daemon=false" 

# Make the gradle wrapper executable. This essentially downloads a copy of 
# Gradle to build the project with. 
# https://docs.gradle.org/current/userguide/gradle_wrapper.html 
# It is expected that any modern gradle project has a wrapper 
before_script: 
    - chmod +x gradlew 

# We redirect the gradle user home using -g so that it caches the 
# wrapper and dependencies. 
# https://docs.gradle.org/current/userguide/gradle_command_line.html 
# 
# Unfortunately it also caches the build output so 
# cleaning removes reminants of any cached builds. 
# The assemble task actually builds the project. 
# If it fails here, the tests can't run. 
build: 
    stage: build 
    script: 
    - ./gradlew -g /cache/.gradle clean assemble 
    allow_failure: false 
    artifacts: 
    name: "AudioBot" 
    paths: 
     - build/libs/*.jar

誰かが私を助けることができればそれはいいだろう。ありがとう！ :)

Answer 1

これはDebianのDockerイメージのバグです。彼らはそれに取り組んでいます：https://github.com/docker-library/openjdk/issues/145

これを直すには、jdk-9-slimイメージを使用できます。 -slimを追加するだけです。

Answer 2

テストの場合、docker-library/openjdkのベースを1つ作ることができます。

docker-library/openjdk issue 19
ca-certificates-java.postinst configureを参照してくださいがPR 111ので、そこにすることになっているが、別のアプローチは、「Error - trustAnchors parameter must be non-empty」に言及した場合、あなたはあなたのカスタムイメージでそれをテストすることができます。

moby/moby issue 18180はかつてはca-certificates-java.postinst configureに影響しましたが、今はOKです。
