속성이 존재하더라도 Ant는 실패하지 않습니다.

Question

Ant 스크립트가 실패 할 곳이 있습니다.

특성 파일 :

application.foo.name=foo 
application.foo.path=[path-to-foo] 
application.foo.file=foo.jar 
appName= 

코드 :

<target name="deploy_app" description="Deploys app"> 
    <condition property="appSelected"> 
    <and> 
     <not> 
     <equals arg1="${appName}" arg2="" /> 
     </not> 
     <isset property="${appName}" /> 
    </and> 
    </condition> 

    <if> 
    <equals arg1="${appSelected}" arg2="true" /> 
    <then> 
    <!-- do nothing! --> 
    </then> 
    <else> 
    <input 
     message="Please enter application name:" 
     addproperty="newAppName" 
    /> 
    <var name="appName" value="${newAppName}" /> 
    </else> 
</if> 
    <antcall inheritAll="true" target="deploy" /> 
</target> 

<target name="deploy"> 
    <echo message="Deploying from property: application.${appName}.file" /> 
    <propertycopy silent="true" name="appFile" from="application.${appName}.file" /> 
    <propertycopy silent="true" name="appPath" from="application.${appName}.path" /> 
    <echo message="appFile: ${appFile}" /> 
    <fail unless="${appFile}" message="appfile: ${appFile} No application with the name ${appName} is defined in your properties file." /> 
</target> 

출력 :

[echo] Deploying from property: application.foo.file 
[echo] appFile: foo.jar 
ERROR: The following error occurred while executing this line: 
appfile: foo.jar No application with the name foo is defined in your properties file. 

그것은 심지어 속성 값을 인쇄,하지만 존재하지 않는 줄 알아!

이유가 무엇입니까?

Answer 1

명령의 unless 매개 변수는 속성 값이 아니라 속성 값을 사용합니다.

고정 된 버전 :

<fail unless="appFile" message="No application with the name ${appName} is defined in your properties file." />
