问题从昨天开始。

https://download.01.org/crosswalk/releases/crosswalk/android/maven2/org/xwalk/xwalk_core_library/maven-metadata.xml 不可用。

更新插件 cordova-plugin-crosswalk-webview 没有帮助。
在 config.xml 中写入变量 name="XWALK_VERSION" value="17+" 没有帮助。
已安装 Android 支持存储库和 Google 存储库。

当我删除该插件时，移动设备上的应用程序会无限加载。

【解决方案1】：

在您的项目根目录中运行find . -name "*xwalk_core_library*"。
打开preview-xwalk.gradle并将compile xwalkSpec行替换为compile 'org.xwalk:xwalk_core_library:VERSION'，其中VERSION是第1步命令返回的版本。

示例：当我运行find . -name "*xwalk_core_library*" 时，我得到结果： ./android/.idea/libraries/xwalk_core_library_20_50_533_12.xml

基于此，我在preview-xwalk.gradle 中的行将如下所示：

compile 'org.xwalk:xwalk_core_library:20.50.533.12'

【解决方案2】：

在 android 项目 *.gradle 中更改你的 gradle 文件 ...

在 xWALK 部分..

dependencies {
    compile 'org.xwalk:xwalk_core_library:23.53.589.4'
}
