文件传输和白名单插件之间似乎存在冲突，一些其他用户也报告了这一点。我的插件列表如下（还有一些需要安装）：

cordova-plugin-android-permissions 1.1.5 "Permissions"
cordova-plugin-app-event 1.2.2 "Application Events"
cordova-plugin-device 2.1.0 "Device"
cordova-plugin-file-md5 0.3.3 "MD5 Checksum"
cordova-plugin-file-transfer 1.7.1 "File Transfer"
cordova-plugin-file 7.0.0 "File"
cordova-plugin-inappbrowser 5.0.0 "InAppBrowser"
cordova-plugin-launcher 0.2.2 "Launcher"
cordova-plugin-media 6.1.0 "Media"
cordova-plugin-network-information 3.0.0 "Network Information"
cordova-plugin-splashscreen 6.0.2 "Splashscreen"
cordova-plugin-whitelist 1.3.5 "Whitelist"
cordova-plugin-x-socialsharing 6.0.4 "SocialSharing"
cordova-plugin-zip 3.1.0 "cordova-plugin-zip"
es6-promise-plugin 4.2.2 "Promise"

安装cordova-plugin-file-transfer后，构建拒绝完成其作业，并给出以下错误：

我还尝试将白名单替换为允许名单，如@Siddhartha Mukherjee建议的in this帖子所示，但这也会产生相同的cannot find symbol错误。
这是工作正常早些时候，但只要我创建了一个新的项目与最新的 cordova 和Gradle最新的Android它停止。任何帮助将不胜感激。
