android - 在 Android Studio 项目中包含 OpenCV 会产生 'Unresolved dependencies' 错误

Question

我正在尝试使用 this 在我的 Android Studio 项目中包含 OpenCV一步一步的指导。但是，在将 OpenCV 添加为模块依赖项(指南中的第 4 步)后，Gradle 项目同步失败并出现以下错误:

ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve project :openCVLibrary410.
Show Details
Affected Modules: app


ERROR: Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve project :openCVLibrary410.
Show Details
Affected Modules: app


ERROR: Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve project :openCVLibrary410.
Show Details
Affected Modules: app

我找到了 this related question并尝试通过添加调试字段来调整 openCV build.gradle 中的 buildTypes，但它没有改变任何东西。我还尝试如下调整应用程序的 build.gradle

    buildTypes {
        release {
            ...
        }
        debug {
            matchingFallbacks = ['release']
        }
    }

(以及几个略有不同的版本，因为我不完全确定我在那里做什么)但没有帮助。我还尝试将 OpenCV 库的构建变体设置为发布而不是调试，但这导致了以下错误:

知道如何解决这个问题吗？

Answer 1

我终于通过改变线路解决了这个问题

应用插件:'com.android.application'

在导入OpenCV模块的build.gradle文件中

应用插件:'com.android.library'

并删除同一个 gradle 文件中的 defaultConfig 字段。我找到了这个解决方案 here .
