Question

我在Maven中使用以下Ant代码

<properties>
    <uninstaller.filename>MyName</uninstaller.filename>
    ....
</properties>
<if>
    <available file="${project.build.directory}/${uninstaller.filename}"/>
    <then>
        <echo> Run Commands.... </echo>                             
        <echo> [INFO]   Done! </echo>
        <echo> [INFO]   Running un-installation...</echo>
        <exec dir="${project.build.directory}"           executable="${project.build.directory}/${uninstaller.filename}**" failonerror="false">
     </exec>
    <echo> [INFO]   My progrm was uninstalled successfully!</echo>
 </then>
<else>
    <echo>[INFO]    No previous program found...</echo>
</else>
</if>

代码找不到我的卸载程序（名称只是MyName而不是MyName。*）但是当我写它时＃34;硬编码＆＃34; -

<available file="${project.build.directory}/MyName"/>

确实有效...... 我检查它是否相同，文件是否存在。该物业也有明确的定义任何的想法？这是可用吗？

感谢

您无需在属性中指定project。

试试此文件mvn install。

如果文件可用，则Ant找不到文件作为属性
