【问题描述】：

我正在尝试将：installDebug.dependsOn(uninstallDebug) 添加到我的构建文件中，例如 this。

添加这个主构建文件失败以及将其添加到应用构建文件（在：android {} 内部或外部）。

感谢您的帮助

【问题讨论】：

很高兴看到错误消息。究竟是什么失败了？

标签： android gradle installation android-gradle-plugin uninstallation

【解决方案1】：

您可以将任务之间的关联推迟到项目完全评估并创建任务之后：

afterEvaluate {
    installDebug.dependsOn(uninstallDebug)
}

在 build.gradle 的顶层执行此操作，而不是在 android 块内。
