无法解析类 targetSdkVersion

Question

我们使用 Microsoft Azure Pipelines 为 ios 和 android 构建 Ionic 应用程序。不幸的是，我们在构建 android 应用程序时遇到以下错误。

FAILURE: Build failed with an exception.

* Where:
Build file '/home/vsts/work/1/s/android/capacitor-cordova-android-plugins/build.gradle' line: 21

* What went wrong:
Could not compile build file '/home/vsts/work/1/s/android/capacitor-cordova-android-plugins/build.gradle'.
> startup failed:
  build file '/home/vsts/work/1/s/android/capacitor-cordova-android-plugins/build.gradle': 21: unable to resolve class targetSdkVersion 
   @ line 21, column 26.
             targetSdkVersion targetSdkVersion = project.hasProperty('targetSdkVersion') ? rootProject.ext.targetSdkVersion : 29

奇怪的是，几天前它没有任何问题地工作。用于生成 APK 的命令

sudo npx jetify

sudo ionic capacitor sync android

cd android && gradle wrapper && sudo ./gradlew assembleRelease `//this is where it fails`

Answer 1

奇怪的是确实如此。我有同样的问题，没有任何好的解释，但我也有一个可行的解决方案。更换线路

targetSdkVersion targetSdkVersion = project.hasProperty('targetSdkVersion') ? rootProject.ext.targetSdkVersion : 29

和

targetSdkVersion project.hasProperty('targetSdkVersion') ? rootProject.ext.targetSdkVersion : 29

工作，对我来说比作业更有意义。

编辑：显然这是正确的修复，电容器存储库中最近的拉取请求也是如此：https : //github.com/ionic-team/capacitor/pull/4788或修复https://github.com/ionic -team/capacitor/pull/4788/commits/250fdcf03be6510dd629a91a98b5220e14d31664
