//环境兼容 gradle wrapper
task wrapper(type: Wrapper){

}

Gradle Command Line

默认分组 xxx-api-v1 默认静态文件 api

gradle createStaticDoc

指定接口分组和静态接口文件

gradle createStaticDoc -P_rest=xxx-ui-v1 -P_static=common

删除并打包 zip

gradle archiveReports

Code Example

动态传入参数

def validate() {
    return project.hasProperty('_param') ? ext._param : false
}

task showParam {
    println validate()
}
//命令行运行 gradle showParam -P_param=Abc
