android - 如何修复无法使用 Jetifier 转换 kotlin-android-extensions-1.3.71.jar' 错误？

Question

任务 ':app:mergeDebugJavaResource' 执行失败。

Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Failed to transform artifact 'kotlin-android-extensions.jar (org.jetbrains.kotlin:kotlin-android-extensions:1.3.71)' to match attributes {artifactType=android-java-res, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}. Execution failed for JetifyTransform: C:\Users\user.gradle\caches\modules-2\files-2.1\org.jetbrains.kotlin\kotlin-android-extensions\1.3.71\ea43e0e563e1915ea845a482fd6f31a948386ab9\kotlin-android-extensions-1.3.71.jar. Failed to transform 'C:\Users\user.gradle\caches\modules-2\files-2.1\org.jetbrains.kotlin\kotlin-android-extensions\1.3.71\ea43e0e563e1915ea845a482fd6f31a948386ab9\kotlin-android-extensions-1.3.71.jar' using Jetifier. Reason: The given artifact contains a string literal with a package reference 'android.support.v4' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx..

就我而言，删除线

    implementation "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

从 app build.gradle 解决了这个问题。 “Kotlin Android 扩展”功能似乎只需添加 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 即可使用在项目 build.gradle 和 apply plugin: 'kotlin-android-extensions' .

以下将是一个相关的问题(但还没有答案):
