推荐项目更新：Android Gradle插件可以升级。错误消息：在生成文件中找不到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，升级助手通知无法在构建文件中找到AGP版本，因此我无法进行升级。

我该怎么办？

谢谢

Answer 1

在我的情况下，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7.0.2版的升级说明。

Answer 2

我不知道这对你的问题很关键，但是修改一下这个

repositories {
    jcenter()
}

到

repositories {
    mavenCentral()
}

应该是需要的。因为jcenter（）已经过时了。
