多个dex文件定义Landroid/support/test/espresso/accessibility/R$attr；

在尝试运行UI测试（androidTest）后，我一直遇到以下错误

My gradle包含以下依赖项：

androidTestImplementation "com.android.support.test.espresso:espresso-core:$espresso"
androidTestImplementation "com.android.support.test.espresso:espresso-contrib:$espresso"
androidTestImplementation "com.android.support.test.espresso:espresso-intents:$espresso"
androidTestImplementation "com.android.support.test.espresso:espresso-accessibility:$espresso"
androidTestImplementation "com.android.support.test.espresso:espresso-web:$espresso"
androidTestImplementation "com.android.support.test.espresso:espresso-idling-resource:$espresso"
androidTestImplementation "com.android.support.test.espresso.idling:idling-concurrent:$espresso"
androidTestImplementation 'com.android.support:multidex-instrumentation:1.0.2'

• 浓缩咖啡3.0.1

请告知

通过强制特定libs版本解决了此问题：

   configurations.all {
        resolutionStrategy {
            // fail eagerly on version conflict (includes transitive dependencies)
            // e.g. multiple different versions of the same dependency (group and name are equal)
            failOnVersionConflict()

            // prefer modules that are part of this build (multi-project or composite build) over external modules
            preferProjectModules()

        force 'com.android.support:appcompat-v7:27.0.1'
        }
    }

并使用此gradle命令查看依赖项树：

./gradlew -q dependencies :project_name:dependencies

libs文件夹中有jar文件吗？我刚刚在我的项目中尝试过，每次包含

espresso可访问性时都会出现此错误。如果您现在不需要它，您可以将其删除以自行解锁。我建议在这里提交一个bug：你能解决这个问题吗？我也一样，是的。问题已经解决了。
./gradlew -q dependencies :project_name:dependencies
