OpenJDK9（Docker），渐变4.2.1，GitLab

Question

我的项目使用graddlew 4.2.1本地生成。但是当我把它推到GitLab上时，我得到下面的错误。 我必须使用Docker，所以我不知道我可以使用这个工具来运行Docker Image。另外这是gitlab-ci.yml：

# 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 

在这里的错误：

这将是很好，如果有人可以帮助我。谢谢！ :)

Answer 1

这是Docker镜像中可能存在的Debian错误。他们的工作我认为：https://github.com/docker-library/openjdk/issues/145

要解决这个问题，可以使用jdk-9-slim图像。只需添加-slim。

Answer 2

要进行测试，您可以在docker-library/openjdk之一上进行测试。

见docker-library/openjdk issue 19
ca-certificates-java.postinst configure应该是有自PR 111，但如果在“Error - trustAnchors parameter must be non-empty”提到的另一种方法，你可以在你的自定义图像对它进行测试。

请注意，moby/moby issue 18180曾经受到影响ca-certificates-java.postinst configure，但现在应该好了。
