我已经将Android Studio更新到2023.1.1，Gradle插件更新到8.2.0。这个Android应用已经有1.5年没有碰过了，我决定编译它并更改目标SDK（现在是33，以前是29）。
在代码编译之前，没有任何警告消息。现在，当我尝试编译时，我得到了很多package not exist错误，如下所示：

我的build.gradle文件如下所示

apply plugin: 'com.android.application'

android {
    signingConfigs {
        config {
            keyAlias '********'
            keyPassword '********'
            storeFile file('D:/work_area/android/apps/keys_store/free_apps/android_free_apps.jks')
            storePassword '********'
        }
    }


    defaultConfig {
        applicationId "ro.notnull.bubblesinline"
        minSdkVersion 21
        targetSdkVersion 33

        versionCode 11
        versionName "1.7.2"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            debuggable false
            signingConfig signingConfigs.config
            shrinkResources true
        }
        debug {
            //buildConfigField("String", "BUILD_TIME", "\"0\"")
            debuggable true
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    namespace 'ro.notnull.bubblesinline'

}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')

    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    implementation "androidx.gridlayout:gridlayout:1.0.0"
    implementation 'androidx.appcompat:appcompat:1.6.1'

    implementation 'com.google.android.gms:play-services-ads:22.5.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.3.2'
    testImplementation 'junit:junit:4.12'

}

型
作为指定的here，我已经添加了testImplementation 'junit:junit:4.12'，但它没有帮助。在我在build.gradle文件//testCompile 'junit:junit:4.12'之前，该行实际上是注解的。
