无法解析类targetSdkVersion

Question

我们使用Microsoft Azure Pipeline为ios和android构建离子应用程序。不幸的是，我们在构建android应用程序时遇到了以下错误。

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，几天前它还能正常工作，没有任何问题。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

这确实很奇怪。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。替换行

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

使用

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

它对我来说比赋值更有意义。

编辑:显然这是正确的修复，最近电容器存储库中的拉取请求做了同样的事情：https://github.com/ionic-team/capacitor/pull/4788或修复https://github.com/ionic-team/capacitor/pull/4788/commits/250fdcf03be6510dd629a91a98b5220e14d31664
