在cordova工程目录下执行一下命令从git服务器上拉取插件目录： cordova plugin add https://github.com/EiyouZk/cordova-plugin-unionpay.git

##错误处理：

Android studio报如下错误： Error:org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

处理方案：打开项目目录/gradle/gradle－wrapper.properties 文件         把distributionUrl=https://services.gradle.org/distributions/gradle-3.3-all.zip 中的gradle-3.3-all.zip替换成其它可运行项目的压缩包（gradle-2.14.1-all.zip）关闭重新打开工程即可。 原因：android studio中gradle的版本导致
