蚂蚁计划终止

我的工作在一些蚂蚁的工具，下面的代码块：蚂蚁计划终止

<trycatch> 
    <try> 
     <if> 
      <equals arg1="${project.dir}" arg2=""/> 
      <then> 
       <fail/> 
      </then> 
     </if> 
    </try> 
    <catch> 
     <echo> 
      &#xa;Project directory not found at the location: ${project.dir} 
      &#xa;Please set your valid project directory in ant configuration file located under path: build/config.properties 
      &#xa;-----------------------------|- Program Terminated -|----------------------------- 
     </echo> 
    </catch> 
</trycatch>

，我也用ant.contrib.jar因为如果，否则...等功能

我的问题是当蚂蚁抛出“project dir not found”这个错误时蚂蚁程序终止了。但它也显示我以下错误后我的错误：

因此，如何删除或控制此BUILD FAIL错误？

似乎有是缺少的东西，将你的目标后运行。请添加您的目标被调用的地方以及目标的定义。 –

您的输出中的异常由'execute'任务引发，这意味着它不会在您上面发布的代码块内发生 - 异常和您的代码不相关。您可以搜索错误消息 - 它似乎是一个文件路径相关的问题。 – coolcfan

哼............ ok –

我想你想终止程序，以防你的<catch>，所以你应该添加一个<throw/>到底。

<?xml version="1.0" encoding="UTF-8"?> 
<project name="test" default="test" basedir="."> 
    <taskdef resource="net/sf/antcontrib/antcontrib.properties"> 
     <classpath> 
     <pathelement location="/usr/share/java/ant-contrib-1.0b3.jar"/> 
     </classpath> 
    </taskdef> 
    <target name="test"> 
     <trycatch> 
      <try> 
       <if> 
        <equals arg1="true" arg2="true"/> 
        <then> 
         <echo>HIT</echo> 
         <fail/> 
        </then> 
        <else> 
         <echo>NO HIT</echo> 
        </else> 
       </if> 
      </try> 
      <catch> 
       <echo> 
        &#xa;Project directory not found at the location: ${project.dir} 
        &#xa;Please set your valid project directory in ant configuration file located under path: build/config.properties 
        &#xa;-----------------------------|- Program Terminated -|----------------------------- 
       </echo> 
       <throw/> 
      </catch> 
     </trycatch> 
    <echo>AFTER ALL</echo> <!-- this shall not be called --> 
    </target> 
</project>

会产生这样的结果：

test: 
HIT 


Project directory not found at the location: ${project.dir} 

Please set your valid project directory in ant configuration file located under path: build/config.properties 

-----------------------------|- Program Terminated -|-----------------------------
