本文详细解析了在Flutter项目中遇到的Gradle依赖问题，并提供了具体的解决方案，包括修改项目的build.gradle文件和Flutter SDK下的flutter.gradle文件，将依赖源更改为阿里云的链接，以解决在中国环境下常见的依赖解析失败问题。

Flutter在Debug项目的时候，应该最常见的错误就是类似下面这样的错误了。

Launching lib/main.dart on Android SDK built for x86 in debug mode...
Initializing gradle...
Resolving dependencies...
* Error running Gradle:
ProcessException: Process "/Users/rabbit/develop/android/flutter_app/android/gradlew" exited abnormally:
Project evaluation failed including an error in afterEvaluate {}. Run with --stacktrace for details of the afterEvaluate {} error.

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/rabbit/develop/android/flutter_app/android/app/build.gradle' line: 25

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not resolve all files for configuration 'classpath'.
   > Could not find lint-gradle-api.jar (com.android.tools.lint:lint-gradle-api:26.1.2).
     Searched in the following locations:
         https://jcenter.bintray.com/com/android/tools/lint/lint-gradle-api/26.1.2/lint-gradle-api-26.1.2.jar

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

这个问题的产生的原因，还是中国特有的问题，解决方案是改位阿里的链接(1.0已经修复了这个问题，不用再重新设置了)。

第一步：修改掉项目下的android目录下的build.gradle文件，把google() 和 jcenter()这两行去掉。改为阿里的链接。

maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }

全部代码：

buildscript {
    repositories {
        //  google()
        //  jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public'}
        }
        dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

allprojects {
    repositories {
        // google()
        // jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

注意是有两个部分进行了修改，不要只修改一处。

第二步：修改Flutter SDK包下的flutter.gradle文件,这个目录要根据你的SDK存放的位置有所变化。比如我放在了D盘Flutter目录下，那路径就是这个。

D:\Flutter\flutter\packages\flutter_tools\gradle

打开文件进行修改，修改代码如下（其实也是换成阿里的路径就可以了）。

buildscript {
    repositories {
        //jcenter()
        // maven {
        //     url 'https://dl.google.com/dl/android/maven2'
        // }
        maven{
            url 'https://maven.aliyun.com/repository/jcenter'
        }
        maven{
            url 'http://maven.aliyun.com/nexus/content/groups/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

然后再重新Debug一下，就基本可以启动起来。

还有一种错误是说硬件没有启动GPU，需要下载安装一个程序，这个提示的很清楚，不做过多的介绍了。
