无法解析组织。项目:TestApp所需的hamcrest:hamcrest-core：{strictly 1.3}

Question

启动connectedDebugAndroidTest gradle任务时出现错误。我对项目执行了同步，它正常完成，但当我启动connectedDebugAndroidTest gradle任务时，该过程失败。

>  Could not resolve all task dependencies for configuration ':TestApp:debugAndroidTestRuntimeClasspath'
    > Could not resolve org.hamcrest:hamcrest-core:{strictly 1.3}
    Required by:
        project :TestApp
        Cannot find a version of 'org.hamcrest:hamcrest-core' that satisfies the version constraints
            Dependency path 'TestApplication:TestApp:unspecified' --> 'androidx.test.ext:junit:1.1.3' --> 'junit:junit:4.12' --> 'org.hamcrest:hamcrest-core:1.3'
            Constraint path 'TestApplication:TestApp:unspecified' --> 'org.hamcrest:hamcrest-core:{strictly 1.3}' because of the following reason: debugRuntimeClasspath uses version 1.3
            Dependency path 'TestApplication:TestApp:unspecified' --> 'androidx.test.espresso:espresso-contrib:3.4.0' --> 'com.google.android.apps.common.testing.accessibility.framework:accessibility-test-framework:3.1' --> 'org.hamcrest:hamcrest-core:2.2'
            Dependency path 'TestApplication:TestApp:unspecified' --> 'androidx.test.espresso:espresso-core:3.4.0' --> 'org.hamcrest:hamcrest-library:2.2' --> 'org.hamcrest:hamcrest-core:2.2'

我的测试依赖项是：

testImplementation "junit:junit:4.13.2"
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation "androidx.test:core:1.4.0"
androidTestImplementation "androidx.test:runner:1.4.0"
androidTestImplementation "androidx.test.espresso:espresso-core:3.4.0"
androidTestImplementation "androidx.test.espresso:espresso-contrib:3.4.0"
androidTestImplementation "androidx.test.espresso:espresso-intents:3.4.0"

Android gradle插件的版本为3.4.3，gradle的版本为5.6

附注：因为我花了2天来解决问题，所以添加了“下一代”的问题

问题是不同的库需要不同版本的hamcrest。为了解决这个问题，我在我的:TestApp build.gradle文件中编写了以下代码：

configurations.all {
    resolutionStrategy {
        force "org.hamcrest:hamcrest-core:2.2"
    }
}

该代码被强制仅使用hamcrest库版本2.2
