Question

请不要将此标记为重复。我花了两天时间搜寻Github，Stack，Android Studio文档，RN文档和Gradle文档以寻找答案。

问题

我们的React Native项目无法在Android上构建。一项构建错误是

Could not find com.github.wix-playground:ahbottomnavigation:2.4.9

fix for this error将maven { url 'https://jitpack.io' }添加到项目build.gradle

但是，添加完之后，我们得到了第二个错误，即

Execution failed for task ':react-native-ble-plx:compileDebugJavaWithJavac'

The fix for this将maven { url 'https://maven.google.com' }添加到build.gradle

但是在添加了第二个修复程序之后，我们再次触发了第一个错误。

问题

是否有一种方法可以列出maven { <url> }中的两个build.gradle，而每个maven { <url> }仅用于依赖它的特定依赖项？

OR

我们可以在所有依赖项中强制使用相同的支持库版本吗？

我从这些Gradle Docs中尝试了许多方法
我已经尝试过此Stack Post
我已更新到Android Studio 3.4.1

任何帮助将不胜感激。

Answer 1

是否有一种方法可以在build.gradle中列出两个maven {}，而每个maven {}仅用于依赖它的特定依赖项？

Matching repositories to dependencies是一个孵化功能。

当前，您可以检查official doc关于定义多个仓库的信息：

您可以定义多个资源库来解决依赖关系。如果某些依赖项仅在一个存储库中可用而在另一个存储库中不可用，则声明多个存储库会很有帮助。

声明的顺序决定了Gradle在运行时如何检查依赖关系。如果Gradle在特定存储库中找到模块描述符，它将尝试从同一存储库下载该模块的所有工件。您可以详细了解Gradle解析机制的内部运作方式。

也

我们可以在所有依赖项中强制使用相同的支持库版本吗？

您可以：

从其中一个依赖项中排除冲突的模块/库
明确声明支持库版本

例如：例如：

  implementation "your dependency:$version" {
       exclude group: "org.xxxx.xxx", module: "xxxxxxx"
   }

使用resolutionStragety，例如：

例如：

android {
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-xxxx:XX.YY.ZZ'
    }
}

请注意这种方法，因为您可能会在某些库中强制使用向后版本。

Answer 2

我们使用了解决策略（请参见上面的评论）来解决我们的问题。另外，在我们的app/build.gradle中，我们决定不使用androidx支持库实现，而是使用较旧的com.android.support:xxx库。最后，解决方案看起来像这样。

app/build.gradle

// Force the same support library version across all dependencies
configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support' && requested.name != 'multidex') {
            details.useVersion "${rootProject.ext.supportLibVersion}"
        }
    }
}

implementation 'com.android.support:design:25.4.0'
implementation 'com.android.support:appcompatv7:${rootProject.ext.supportLibVersion}'

Answer 3

使用此命令可以在单个命令中添加多个依赖项

all the cell of column_dataset_2_normalized

也请明智地使用本机版本

react-native init --version =“ react-native@0.36.0” MyNewApp

react-native初始化--version =“ react-native@0.59.8” MyNewAppName
