android - Gradle 4.0 找不到匹配的配置

Question

我正在尝试在新的 Android Studio 3.0 canary 2 中打开我现有的项目。我根据 instructions 更新了 Gradle ，更改了依赖配置的名称，但我继续收到下一个错误:

Unable to resolve dependency for ':app@productionRelease/compileClasspath': 
Could not resolve project : abChat.

在另一个窗口中:

Error:Could not resolve all dependencies for configuration ':bankOK:betaNewApiInnerTestRuntimeClasspath'.
> Unable to find a matching configuration in project :abChat:

以下是我们的构建类型和风格:

buildTypes {

        release {
           //...
        }

        debug {
           //...
        }

        innerTest {
            //...
        }
    }



flavorDimensions "releaseType", "apiLvl"
    productFlavors {
        prod {
            dimension "releaseType"
            //...
        }
        beta {
            dimension "releaseType"
            //...
        }
        oldApi {
            dimension "apiLvl"
           //...
        }
        newApi {
            dimension "apiLvl"
            //...
        }
    }

此外，我们还有一个名为“abChat”的库模块，没有任何风格。我可以尝试做些什么来解决这个问题？

此问题已修复，并且在 Stable 3.0 版本中一切正常。如果你仍然面临这个问题，那是因为没有回退机制。

如果您的应用包含库不包含的构建类型，那么您将收到此错误。要解决此问题，您需要为您的构建类型提供 matchingFallbacks。请参阅解决与依赖匹配相关的构建错误部分in this documentation

如果是构建类型，请执行以下操作，如果是产品风格，请参阅迁移文档。

buildTypes {
    release {
       //...
    }
    debug {
       //...
    }
    innerTest {
        //...
        matchingFallbacks = ['debug', 'release']
    }
}

并简单地添加您的依赖项，如下所示:

dependencies {
    implementation project(':abChat')
}
