Gradle构建失败：无法找到方法'org.gradle.api.tasks.testing.Test.getTestClassesDirs（）Lorg / gradle / api / file / FileCollection;'

Question

当我尝试从github编译导入的project时，我的gradle构建总是失败，并带有以下例外。

Unable to find method 'org.gradle.api.tasks.testing.Test.getTestClassesDirs()Lorg/gradle/api/file/FileCollection;'
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)</li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)</li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes

我按照给出的指示，但没有成功。此外，我无法通过在互联网上搜索有关错误的任何进一步信息

gradle这个\ gradle-wrapper.properties：

#Thu May 18 17:31:31 EEST 2017
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.0-milestone-1-all.zip

有谁知道为什么会出现这个错误？

Answer 1

我不得不将gradle-wrapper.properties中的distributionUrl更改为distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip以使构建再次运行。这似乎是一个类似的问题Gradle sync failed: Unable to find method。

Answer 2

看起来你没有解决你的testInstrumentation。你在使用facebook.screenshot api吗？如果是这样你需要包括它。

否则，只需注释掉testInstrument部分，看看如果不关心它们，是否可以在没有测试的情况下进行构建。否则你需要修复它的依赖用法。

*注释掉testInstrumentationRunner“android.support.test.runner.AndroidJUnitRunner”

这会导致在清单中创建一行，并且可能无法正确解析。

Answer 3

for android studio path“folder project / gradle / wrapper / gradle-wrapper.properties”文件更改URL值distributionUrl = https://services.gradle.org/distributions/gradle-4.10.1-all.zip适当的（上一个）版本来自http://services.gradle.org/distributions/
