从grails项目执行gant脚本 [英] Executing a gant script from a grails project

问题描述

我写了我自己的gant脚本，它在命令行中可以正常工作。现在我需要从这样的grails项目运行这个脚本：

  def outputMessage 
 
 try { 
 
 GroovyScriptEngine engine = new GroovyScriptEngine（/ www，this.getClass（）。getClassLoader（））; 
 engine.run（scripts / MyOwnScript_.groovy，param1 param2）
 outputMessage =< br> OK：脚本成功运行

 catch（Exception e）{
 outputMessage + =< br>错误：已经运行脚本

  

我得到的错误是No such property：includeTargets for class：MyOwnScript_，因为我的脚本需要一些其他脚本。

有人知道一个正确的方法来解决它吗？

解答方案

回答我自己的问题。

  Map< String，String>我们需要使用完整路径来运行grails。 env = System.getenv（）
 final ProcessBuilder = new ProcessBuilder（）
 processBuilder.directory（new File（folderFromWhereIWantToRunTheGantScript））
 processBuilder.command（[env ['GRAILS_HOME'] + / bin / grails，MyOwnScript param1 param2]）
 println processBuilder.directory（）
 Process proc = processBuilder.start（）
 proc.consumeProcessOutput（out，err）
 
 proc.waitFor（）
  

I have written my own gant script which works fine from the command line. Now I need to run this script from a grails project like this:

def outputMessage

try{

    GroovyScriptEngine engine = new GroovyScriptEngine("/www", this.getClass().getClassLoader());
    engine.run("scripts/MyOwnScript_.groovy", "param1 param2")
    outputMessage = "<br> OK: Script run successfully"
}
catch (Exception e) {
    outputMessage += "<br> ERROR: There has been running the script"
}

The error I am getting is "No such property: includeTargets for class: MyOwnScript_", as my gant script requires some other scripts.

Does anybody know a proper way to get it working?

解决方案

Answering my own question. The main problem was that I need to run the grails using the full path like this:

Map<String, String> env = System.getenv()
final processBuilder = new ProcessBuilder()
processBuilder.directory(new File("folderFromWhereIWantToRunTheGantScript"))
processBuilder.command([env['GRAILS_HOME']+"/bin/grails","MyOwnScript param1 param2"])
println processBuilder.directory()
Process proc = processBuilder.start()
proc.consumeProcessOutput(out, err)

proc.waitFor()
