Ant 保存和加载属性

我尝试编写ant任务，它执行以下操作（伪代码）：

所以，换言之，如果我第一次运行脚本，它必须询问一些值，并保存该值以备将来使用

---

最重要的是，它只能用于ANT核心任务。

您可以尝试以下方法：

  <target name="load-properties">
    <property file="test.properties" />
  </target>

  <target name="ask-user" unless="my-property" >
    <input
       message="Please provide property"
       addproperty="my-property" />
     <echo file="test.properties" message="my-property=${my-property}" />
  </target>

  <!-- try to load properties-file first, ask user if property is not found -->
  <target name="main" depends="load-properties, ask-user">
    <echo>${my-property}</echo>
  </target>

${my property}

  <target name="load-properties">
    <property file="test.properties" />
  </target>

  <target name="ask-user" unless="my-property" >
    <input
       message="Please provide property"
       addproperty="my-property" />
     <echo file="test.properties" message="my-property=${my-property}" />
  </target>

  <!-- try to load properties-file first, ask user if property is not found -->
  <target name="main" depends="load-properties, ask-user">
    <echo>${my-property}</echo>
  </target>
