螞蟻javascript和套接字numberformatexception

我有這個螞蟻目標來驗證，如果一個端口被佔用。該腳本實際上獲得了8080的正確端口，儘管出於某種原因有一條新線。螞蟻javascript和套接字numberformatexception

<loadfile srcfile="hudson.xml" property="port"> 
      <filterchain> 
       <scriptfilter language="javascript"> 
       if (self.getToken().indexOf("httpPort") != -1) 
        self.setToken(parseInt(self.getToken().substring((self.getToken().indexOf("httpPort")+9),(self.getToken().indexOf("httpPort")+9) + 4))); 
       else 
        self.setToken(null); 
       </scriptfilter> 
       <ignoreblank/> 
       <trim/> 
      </filterchain> 
    </loadfile> 

    <echo message="Checking whether Hudson is running"/> 
    <condition property="hudson.running"> 
     <socket server="localhost" port="${port}"/> 
    </condition>

這會拋出一個Numberformatexception。我需要解析這個端口的hudson.xml文件並驗證它目前沒有被使用。有什麼建議？

您需要在filterchain多了一個過濾器 - stripinebreaks。

你的scriptfilter只用行上找到的端口號來代替整行，但不會在最後刪除新行。
