AndroidStudioGradle:使用GoogleServicesPlugin忽略注釋

2022-10-29 02:53:22 資料庫

我已經搜索了我可以在堆疊溢位以及其他類似網站上找到的所有答案,但那里的解決方案并不能解決我的問題。

我正在嘗試將舊專案上的構建工具從 sdk 28 更新到 sdk 31,以符合 Google Play 商店的安全要求,但每次運行時ionic cordova build android --stacktrace都會得到以下結果:

FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':app:processDebugGoogleServices' (type 'GoogleServicesTask').
  - In plugin 'com.google.gms.googleservices.GoogleServicesPlugin' type 'com.google.gms.googleservices.GoogleServicesTask' field 'intermediateDir' without corresponding getter has been annotated with @OutputDirectory.
    
    Reason: Annotations on fields are only used if there's a corresponding getter for the field.
    
    Possible solutions:
      1. Add a getter for field 'intermediateDir'.
      2. Remove the annotations on 'intermediateDir'.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

根據其他答案,這似乎意味著我使用的是舊版本的com.google.gms:google-services:4.3.10插件,但我找不到呼叫它的位置。

我試過的:

  • 添加ext{ GOOGLE_SERVICES_VERSION='4.3.10'}到我的全域allProjectsbuild.gradle。這并沒有改變結果
  • apply plugin: 'com.google.gms.google-services'在本地 build.gradle 中注釋該行。這將錯誤訊息從Cannot add extension with name 'googleServices', as there is an extension already registered with that name.上面顯示的錯誤更改。這也在 build.gradle 中的類似塊中進行了嘗試,如下所示。
  • 我添加了<preference name="GradlePluginGoogleServicesVersion" value="4.3.14" /> <preference name="AndroidXEnabled" value="true" />config.xml。這似乎已經標準化了版本號,但并沒有解決問題。
  • 我洗掉并重新添加了 android ,ionic cordova platform remove android但是ionic cordova platform add android這個重置并沒有改變問題
  • 更改classpath 'com.google.gms:google-services:4.3.10'/platforms/android/build.gradle 和 /platforms/android/app/build.gradle 中的版本。我對此感到困惑,因為每次我嘗試構建時,它都會變回或與舊版本重復,但我不知道這是從哪里來的。
  • 確保 google-services.json 包含所有必要資訊。我已經從 firebase 下載并重新下載了這個檔案,它并沒有改變結果。

我想我的主要問題是:如何確保我使用的是正確版本的 google-services?

我知道這是舊東西,但我希望通過將我找到并嘗試過的所有答案編譯到一個地方,我可以幫助其他試圖更新舊應用程式的人。

uj5u.com熱心網友回復:

基本上,我的解決方案是重新安裝。為了解決這個問題,我只是在一個新分支上重新安裝了該專案并重新開始。我還重新安裝了我的構建工具,但我認為這對結果沒有任何重大影響。然后,我將目標 SDK 更改為 32,啟用了 android X,并更新了一些舊的 Cordova 插件。
