cordova - ionic : compileSdkVersion is not specified

Question

我正在尝试运行以下命令:

ionic cordova run android --device

但我收到以下错误

    BUILD FAILED in 3s

我尝试删除和添加 android 平台

ionic cordova platform rm android
ionic cordova platform add android

但是还是一样的错误。任何帮助，将不胜感激。谢谢。

Answer 1

我没有粘贴我在问题中收到的整个错误，因为 stackoverflow 不允许我发布，因为有很多“代码”(我应该将错误粘贴为简单文本，而不是代码)

无论如何，错误行之一是

FAILURE: Build failed with an exception.

* Where:
Build file 'D:\xyz\idek\platforms\android\app\build.gradle' line: 95

因此，我查看了 app\build.gradle 中的第 95 行，它与我使用的 FCM 插件有关。所以我继续从我的应用程序中删除了该插件。

ionic cordova plugin rm cordova-plugin-fcm-with-dependecy-updated
npm uninstall --save @ionic-native/fcm

此外，您还必须在使用此插件的应用中注释代码。

现在我的应用程序成功运行了。我还没有找到为什么这个插件会导致问题。

编辑

FCM插件不工作的解决方案在这里https://github.com/andrehtissot/cordova-plugin-fcm-with-dependecy-updated/pull/2

它所做的是，将 FCMPlugin.gradle 中的所有 jcenter() 替换为 mavenCentral()
