Question

我从GitHub存储库中克隆了一个正在工作的应用程序。我还没有启动它。这是我们继承的项目，以前的开发人员都没有。我只是在学习来自Xamarin背景的React Native。

尝试运行“ react-native run-android”无效。它返回：

Failed to notify ProjectEvaluationListener.afterEvaluate(), but primary configuration failure takes precedence.
java.lang.IllegalStateException: buildToolsVersion is not specified.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

我在这里阅读了一些答案，表明它可能与我的build.gradle有关。最新的是

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url 'https://maven.fabric.io/public'
        }
    }
}

我已经能够运行新的应用程序。他们的build.gradle看起来像这样：

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

我已尝试使用此build.gradle，但由于调用了“ google（）”而无法运行。

我没有GitHub原始文件中指定的Gradle版本。

我尝试将build.gradle修改为说classpath: 'com.android.tools.build:gradle:2.2.0'指向现有版本，但是由于相同的“ buildToolsVersion”错误而无法正常工作。

修改在得到同事的建议后，我走得更远。这个问题已经解决，但是我现在遇到其他错误。那是另一个故事了。简而言之，我在Android Studio中打开了Android项目。它帮助我了解了正在发生的事情并与Gradle一起工作。对于那些将来会发现此问题的人，这里有一些更改。

我将google()添加到了build.gradle的存储库和所有项目{repositories {..}}

我确认自己在本地构建了工具，并且设置正确（以我的情况为25.0.3）。

我修改了gradle-wrapper.properties以使其具有distributionUrl = https：//services.gradle.org/distributions/gradle-5.1.1-all.zip

React Native项目不会以各种错误运行，包括“ java.lang.IllegalStateException：未指定buildToolsVersion。”
