개미 프로그램

Question

나는 어떤 개미 도구 작업과 다음 오전

는 코드 블록 종료 :

<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> 

나는 또한에 대한 경우 ant.contrib.jar을 사용하고, 다른 ... 등 기능

문제는 개미가 "project dir not found"라는 오류를 던져서 개미 프로그램이 잘 종료되는 것입니다.

그래서 내가 어떻게 제거하거나이 빌드가 오류를 FAIL 제어 할 수 있지만, 나 또한 내 오류가 발생한 후 오류를 다음 보여줍니다?

Answer 1

<catch>의 경우 프로그램을 종료하고 싶으므로 마지막에 <throw/>을 추가해야합니다.

<?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> 

는이 결과를 생성합니다

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 -|-----------------------------
