我遇到“无法解决依赖关系”的问题

Question

我想在我的android项目中使用opencv。通过“导入模块”导入opencv SDK。当我进行snyc时，它向我显示此错误：

ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve project :openCVLibrary.
Show Details
Affected Modules: app


ERROR: Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve project :openCVLibrary.
Show Details
Affected Modules: app


ERROR: Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve project :openCVLibrary.
Show Details
Affected Modules: app

我尝试了许多方法。

  

  
1. 更改compileSdkVersion，现在compileSdkVersion为29。
  
2. 删除像这样的全局gradle.properties代码
     systemProp.http.proxyHost = 127.0.0.1
     systemProp.https.proxyPort = 1087
     systemProp.https.proxyHost = 127.0.0.1
     systemProp.http.proxyPort = 1087
  
3. 将HTTP代理更改为无代理
