Robolectric 连接超时无法下载

Question

我正在尝试为我的 Kotlin 应用程序编写 Robolectric 测试，但无法运行我的测试，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，因此我在这里提出问题。

\n\n

我使用的是Android Studio 3.6

\n\n

我看到错误

我的应用程序的“build.gradle”

\n\n

我的测试

\n\n

@RunWith(RobolectricTestRunner::class)\nclass MyTest {\n    @Rule @JvmField\n    val instantExecutorRule = InstantTaskExecutorRule()\n\n    @Before\n    @Throws(Exception::class)\n    fun setUp() {\n        // set up all my mock objects\n    }\n\n    @Test\n    fun test1() {\n       ....\n    }\n}\n

在 2 个存储库 URL 中找不到 robolectric

\n\n

\n

• 我尝试访问“ https://oss.sonatype.org/content/groups/public/ ”，但收到错误“目录列表被禁止”。当我从 URL 中删除尾随 / 时，出现错误“This oss.sonatype.org page can\xe2\x80\x99t be find”

\n

• 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

\n\n

一个答案说这个问题是代理问题。我在“gradle.properties”中设置了代理，并且没有其他依赖项存在下载问题。

\n\n

systemProp.http.proxyHost=myproxy-server.com\nsystemProp.https.proxyPort=80\nsystemProp.https.proxyHost=myproxy-server.com\nsystemProp.http.proxyPort=80\n

\n\n

尝试修复 2：build.gradle 告诉它使用 Maven 存储库

\n\n

一个答案说要指定用于 robolectric 下载的 Maven 存储库。但这没有什么区别。

\n\n

testOptions {\n    unitTests {\n        all {\n            systemProperty \'robolectric.dependency.repo.url\', \'https://repo1.maven.org/maven2/\'\n        }\n    }\n

\n\n

尝试修复 3：在我的存储库中包含“mavenCental()”

\n\n

我尝试将“mavenCentral()”添加到我的“build.gradle”文件中，但没有解决问题。

\n\n

buildscript {\n    ext.kotlin_version = \'1.3.31\'\n\n    repositories {\n        google()\n        jcenter()\n        mavenCentral()\n    }\n    dependencies {\n        classpath \'com.android.tools.build:gradle:3.5.1\'\n        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"\n        classpath \'org.robolectric:robolectric-gradle-plugin:0.11.+\'\n    }\n}\n\nallprojects {\n    repositories {\n        google()\n        jcenter()\n        mavenCentral()\n    }\n}\n

\n\n

建议的解决方案“enableUnitTestBinaryResources”

\n\n

另一篇文章说将“android.enableUnitTestBinaryResources=true”添加到gradle.properties。

\n\n

robolectric 说明说，Android Studio 3.3+ 不需要此配置，我使用的是 AS 3.6。

Answer 1

我尝试了你尝试过的一切。这些事情都没有为我解决问题——或者至少在我执行之前没有解决这个问题

rm -rf ~/.m2删除我的本地 Maven 缓存。
