如何在运行gradle任务时在命令行中传递多个参数？ [英] How to pass multiple parameters in command line when running gradle task?

问题描述

我有一个由gradle任务运行的java和groovy类。我设法使它工作，但我不喜欢我必须在命令行中传递参数的方式。以下是我现在通过命令行执行的操作： gradle runTask -Pmode['doStuff'，'username'，'password']

我的build.gradle代码接受这些参数如下所示：

  if（project.hasProperty（mode））{
 args Eval.me（mode）} 
  

然后我在我的参数/参数java代码如下：

  String action = args [0]; //doStuff
 String name = args [1]; .. //用户名
  

我想知道有没有办法将参数传递给更好例如：

  gradle runTask -Pmode = doStuff -Puser = username -Ppass = password 
  
 
以及如何在我的java类中使用它们。
解决方案
  JavaExec 可能是一条可行的路。只需声明一个任务并将项目参数传递给Java应用程序： 
 
 
 任务myExecTask（类型：JavaExec）{
 classpath = sourceSets.main.runtimeClasspath 
 main ='com.project.MyApplicationMainClass'
 args project.getProperty（'userName'）+''+ project.getProperty（'password'）; 
} 
  
要运行它，只需编写 gradle myExecTask -PuserName = john -Ppassword = secret  
 
I've got a java and groovy classes that are being run by gradle task. I have managed to make it work but I do not like the way I have to pass the parameters in command line. Here is how I do it currently via command line: gradle runTask -Pmode"['doStuff','username','password']"

my build.gradle code which takes these parameters looks like this:         
if (project.hasProperty("mode")) {
args Eval.me(mode)}
and then I use my arguments/parameters in my java code as follows: 
String action = args[0]; //"doStuff"
String name = args[1]; .. //"username"
I was wondering is there a way to pass the parameters in a better way such as: 
gradle runTask -Pmode=doStuff -Puser=username -Ppass=password 
and how to use them in my java classes.
解决方案
JavaExec may be the way to go. Just declare a task and pass project parameters to java app:
task myExecTask(type: JavaExec) {
   classpath = sourceSets.main.runtimeClasspath
   main = 'com.project.MyApplicationMainClass' 
   args project.getProperty('userName') + ' ' + project.getProperty('password');
}
To run it, simply write gradle myExecTask -PuserName=john -Ppassword=secret
