Question

所以我为Android创建了一个Qt项目，但每当我尝试构建它时，我都会遇到异常。我甚至尝试在命令行中运行gradlew文件，结果相同。无论我在网上看哪，它似乎都是https://docs.gradle.org/current/userguide/userguide_single.html#properties第12.3节中指出的代理或网络问题。我用两个不同的网络进行了双重检查，并且我没有使用代理服务器。

这是自动生成的build.gradle（它有什么问题吗？）

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

apply plugin: 'com.android.application'

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

android {
    /*******************************************************
     * The following variables:
     * - androidBuildToolsVersion,
     * - androidCompileSdkVersion
     * - qt5AndroidDir - holds the path to qt android files
     *                   needed to build any Qt application
     *                   on Android.
     *
     * are defined in gradle.properties file. This file is
     * updated by QtCreator and androiddeployqt tools.
     * Changing them manually might break the compilation!
     *******************************************************/

    compileSdkVersion androidCompileSdkVersion.toInteger()

    buildToolsVersion androidBuildToolsVersion

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = [qt5AndroidDir + '/src', 'src', 'java']
            aidl.srcDirs = [qt5AndroidDir + '/src', 'src', 'aidl']
            res.srcDirs = [qt5AndroidDir + '/res', 'res']
            resources.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
       }
    }

    lintOptions {
        abortOnError false
    }
}

任何指针或想法都将不胜感激！

[第二次修改]

将网址更改为http（不安全）或让gradlew获取本地文件后，我得到了这个：

* What went wrong:

Answer 1

看起来你在

之后就遇到了错误

正在下载https://services.gradle.org/distributions/gradle-3.4-bin.zip

所以我只是尝试通过cURL来打击它，

$curl --head https://services.gradle.org/distributions/gradle-3.4-bin.zip

HTTP/1.1 301 Moved Permanently
Date: Fri, 02 Jun 2017 20:13:00 GMT
Connection: keep-alive
Cache-Control: max-age=3600

Location: https://downloads.gradle.org/distributions/gradle-3.4-bin.zip
Server: cloudflare-nginx
CF-RAY: 368d121d6ad9568d-IAD

这显示301重定向，如果下载代码未正确处理，则可以解释Connection reset。我不知道这个URL的来源，但你可以尝试用新目的地替换它：

https://downloads.gradle.org/distributions/gradle-3.4-bin.zip

回答＃2

您可以升级并使用2.3.0吗？这似乎是最新的is definitely available in Central。
