android - Android Studio 3.4.2- Unresolved reference v7

标签 android android-studio gradle android-gradle-plugin

我更新到Android Studio 3.4.2，并且按预期的那样，我遇到了很多错误，主要是gradle错误。
我设法解决了所有问题，但我还剩一个似乎无法解决的问题- Unresolved reference v7。我一直在尝试我能找到的一切，但到目前为止还没有运气。

错误发生在import android.support.v7.app.AppCompatActivity上

这是build.gradle文件:
应用插件:“com.android.application”
应用插件:“kotlin-android”
应用插件:“kotlin-android-extensions”

android
{
    compileSdkVersion 28
    defaultConfig
            {
                applicationId "com.bogdangheorghe.nutritivo"
                minSdkVersion 19
                targetSdkVersion 28

                versionName "1.0.0"
                testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
            }
    buildTypes

                        }
            }
    configurations.all
            {
                resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
            }
    compileOptions {

        sourceCompatibility 1.8
    }
}

    implementation('com.google.api-client:google-api-client-android:1.22.0')
            {
                exclude group: 'org.apache.httpcomponents'
            }
    implementation('com.google.apis:google-api-services-drive:v3-rev29-1.22.0')
            {

            }
    implementation 'com.android.support:support-annotations:28.0.0'
}

有什么我想念的吗？

另外，当我尝试清理并重建项目时，构建过程会失败，并且我得到以下信息:
