如何解决android gradle构建错误？

Question

每当我尝试使用 cordova 或 android studio 构建 android 时都会出现以下错误：

Error: Error code 1 for command: cmd with args: /s,/c,..\platforms\android\gradlew cdvBuildDebu

如何解决？

Answer 1

可能有两个原因

1. 您很可能有此库的旧版本，并且在构建文件中您使用的是新版本。所以试试这个，

   转到项目结构 => 依赖项 => 库依赖项并添加您拥有的一项并删除前一项。

2. 您的 SDK 没有此依赖项，工作室正在尝试下载它，所以让它发生，因为它是支持旧的重要库安卓设备平台。

Answer 2

它需要下载该库才能进行构建，但您已将 Android Studio 置于离线模式。

要修复它，请转到 Preferences > Gradle and ensure that the "Offline work" 复选框未选中。

转到设置 -->> 搜索 Gradle -->> 点击 gradle -->> 取消选中离线 工作

Answer 3

检查您build.gradle 以降级您的 SDK 版本，如果您特别需要此版本，只需下载并同步即可。

Answer 4

一定要有：（在你的 build.gradle 主设置项目中）

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }

}
