Gradlew 抛出 java.net.SocketException

Question

因此，我为 Android 创建了一个 Qt 项目，但每当我尝试构建它时，我都会遇到该异常。我什至尝试在命令行中运行 gradlew 文件，得到相同的结果。无论我在网上查找什么，这似乎都是代理或网络问题，如https://docs.gradle.org/current/userguide/userguide_single.html#properties第 12.3 节中指出的那样。我仔细检查了两个不同的网络，并且我没有使用代理服务器。

这是自动生成的build.gradle（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
    }
}

任何指示或想法将不胜感激！

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

FAILURE: Build failed with an exception.

* What went wrong:

Answer 1

看来您之后立即遇到了错误

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

所以我只是尝试通过 cURL 击中这个，

$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
Expires: Fri, 02 Jun 2017 21:13:00 GMT
Location: https://downloads.gradle.org/distributions/gradle-3.4-bin.zip
Server: cloudflare-nginx
CF-RAY: 368d121d6ad9568d-IAD

这显示了 301 重定向，这可以解释Connection reset下载代码是否未正确处理它。我不知道这个 URL 来自哪里，但您可以尝试将其替换为新的目的地：

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

答案#2

可以升级使用2.3.0吗？这似乎是最新的，并且在中环肯定有售。
