【问题描述】：
当我尝试从 github 编译导入的 project 时，我的 gradle 构建总是失败并出现以下异常。
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
我按照给出的说明进行操作，但没有成功。此外，我无法通过在互联网上搜索得到有关该错误的更多信息
