settings.gradle.kts:

     rootProject.name = "a-restful"

 

使用命令编译打包:

gradle build -Penv=dev -Dfile.encoding=UTF-8 --daemon
gradle build -Penv=prod -Dfile.encoding=UTF-8 --daemon

-Penv的值为config.groovy中的配置

执行编译打包命令后,会将config.groovy中配置的变量替换文件中的占位符@xx@

kotlin_app\build\libs下生成jar包名: a-restful-0.0.1.jar
