Android Studio 3.0 Gradle 同步失败 : java. lang.AssertionError(在 UnresolvedDependenciesReporter 中)

Question

当迁移到 Android Studio 3.0-beta1 时，我遇到了一个没有提供太多信息的 gradle sync failed 错误。 gradle 控制台中没有错误消息。我必须转到 idea.log 文件以获取以下堆栈跟踪:

我关注了 migration documentation但仍然无法使同步成功运行。不确定这是否是 Android Studio 3.0-beta1 或我的项目配置中的问题。我运行过其他项目并使用 Android Studio 3.0-alphaX 创建了新项目，因此更倾向于我的项目。

Answer 1

问题是我没有为缺少的构建类型选择默认值。我的项目有 2 个模块，具有以下构建类型配置:

数据/build.gradle

apply plugin: 'com.android.library'
android {
    ...
    buildTypes {
        debug { ... }
        release { ... }
    }
}

应用程序/build.gradle

apply plugin: 'com.android.application'
android {
    ...
    buildTypes {
        debug { ... }
        dev { ... }
        qa { ... }
        rc { ... }
        release { ... }
    }
}

使用最新的 Android gradle 插件，您的构建类型必须与库和应用程序模块相匹配。我的问题是我的数据模块没有定义 dev、qa 和 rc 构建类型。我通过在我的应用程序模块中使用 buildTypeMatching 解决了这个问题:

应用程序/build.gradle

apply plugin: 'com.android.application'
android {
    ...

    buildTypeMatching 'dev', 'debug'
    buildTypeMatching 'qa', 'debug'
    buildTypeMatching 'rc', 'release'

    buildTypes {
        debug { ... }
        dev { ... }
        qa { ... }
        rc { ... }
        release { ... }
    }
}

您也可以将缺失的变体添加到库模块中。

我遇到了这个bug report这似乎是我同样的问题。看起来错误消息中有一个错误，希望能得到修复。
