Question

就在最近推出的世博会，我正在尝试在 Android 设备上运行我的应用程序。我按照说明操作(希望是正确的)，但是当我尝试运行我的应用程序时，我不断收到此错误:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.0.1/userguide/command_line_interface.html#sec:command_line_warnings

我在 Windows 上遇到了同样的问题，我的问题是 Gradle local.properties文件。
它包含以下内容:

org.gradle.java.home=C:\Program Files\Java\jdk-15.0.1
sdk.dir=C:\Users\user\AppData\Local\Android\Sdk

问题可能是 Windows 反斜杠 ( \ )。有效的是逃避它:

org.gradle.java.home="C:\\Program Files\\Java\\jdk-15.0.1"
sdk.dir=C:\\Users\\user\\AppData\\Local\\Android\\Sdk
