项目更新推荐：Android Gradle 插件可以升级。错误消息：在构建文件中找不到 AGP 版本

Question

在 Android Studio 中建议将 Android Gradle 插件从 7.0.0 升级到 7.0.2 后，升级助手通知 找不到 AGP 版本在构建文件中，因此我无法进行升级。

我该怎么办？

谢谢

build.gradle 中的代码（项目）

代码位于 build.gradle.kts

repositories {
    jcenter()
}

plugins {
    `kotlin-dsl`
}

Answer 1

我不知道它是否对你的问题很重要，但修改这个

repositories {
    jcenter()
}

至

repositories {
    mavenCentral()
}

应该需要。因为 jcenter() 已过时。

Answer 2

在我的例子中，以下步骤解决了这个问题：

cd to project directory
bash ./gradlew help --scan
bash ./gradlew wrapper --gradle-version 7.0.2

请参阅 gradle 发行说明中的 upgrade instructions to version 7.0.2。
