【问题描述】：
我正在尝试为我的 Kotlin 应用程序编写一个 Robolectric 测试，但我无法运行我的测试，因为它无法下载 Robolectric。我在 StackOverflow 和 Google 上进行了搜索，但没有任何建议可以解决我的问题，因此我的问题在这里。
我使用的是 Android Studio 3.6
我看到了错误

Unable to resolve artifact: Missing:
----------
1) org.robolectric:android-all:jar:9-robolectric-4913185-2
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=org.robolectric -DartifactId=android-all -Dversion=9-robolectric-4913185-2 -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=org.robolectric -DartifactId=android-all -Dversion=9-robolectric-4913185-2 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) org.apache.maven:super-pom:pom:2.0
2) org.robolectric:android-all:jar:9-robolectric-4913185-2
----------
1 required artifact is missing.
for artifact:
org.apache.maven:super-pom:pom:2.0
from the specified remote repositories:
central (http://repo1.maven.org/maven2),
sonatype (https://oss.sonatype.org/content/groups/public/)
我的应用的“build.gradle”

在 2 个 repos URLS 中找不到 robolectric
我已尝试访问“https://oss.sonatype.org/content/groups/public/”，但收到错误“禁止列出目录”。当我从 URL 中删除尾随 / 时，我收到错误“找不到此 oss.sonatype.org 页面”
转到“https://repo1.maven.org/maven2”（必须是 https 而不是 http）“robolectric”没有子文件夹
尝试修复 1：代理
一个答案说问题是代理问题。我在“gradle.properties”中设置了代理，并且没有其他依赖项有下载问题。
systemProp.http.proxyHost=myproxy-server.com
systemProp.https.proxyPort=80
systemProp.https.proxyHost=myproxy-server.com
systemProp.http.proxyPort=80
尝试修复 2：build.gradle 告诉它使用 maven repos
一个答案是指定用于 robolectric 下载的 maven 存储库。但这并没有什么区别。
testOptions {
unitTests {
all {
systemProperty 'robolectric.dependency.repo.url', 'https://repo1.maven.org/maven2/'
}
}
尝试的修复 3：在我的存储库中包含“mavenCental()”
我尝试将“mavenCentral()”添加到我的“build.gradle”文件中，但没有解决。
buildscript {
ext.kotlin_version = '1.3.31'
repositories {
google()
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'org.robolectric:robolectric-gradle-plugin:0.11.+'
}
}
allprojects {
repositories {
google()
jcenter()
mavenCentral()
}
}
建议的解决方案“enableUnitTestBinaryResources”
另一个帖子说要在 gradle.properties 中添加“android.enableUnitTestBinaryResources=true”。
robolectric 说明说，Android Studio 3.3+ 不需要此配置，我使用的是 AS 3.6。
