Question

我有一个属性文件，我想将所有键和值传递给命令，我该怎么做？

说属性文件看起来像文件

size=small
perf=true

并且ant任务看起来像

    <exec executable="${prog}" failonerror="true">
<!-- I want to add all properties from file as argument here, -->
    </exec>

以便在运行时，行为符合

<exec executable="${prog}" failonerror="true">
   <arg value = "size"/>
   <arg value = "small"/>
   <arg value = "perf"/>
   <arg value = "true"/>
</exec>

我该怎么做？感谢

编辑：

根据Vadzim的建议，我现在正在使用脚本。

<property file="test.properties" prefix="testproperty"/>
<target name = "test1">
<script language="javascript"> <![CDATA[
  properties = project.getUserProperties()
  echo = project.createTask( "echo" );
  anotation = project.getProperty("testproperty.size")
  echo.setMessage(anotation);
  echo.perform();
  for(key in properties) {
    echo.setMessage(key);
    echo.perform();
    echo.setMessage(properties[key]);
    echo.perform();
  }
]]> </script>
</target>

但是，getProperty（）正在运行，但getProperties只包含java函数，如notify（）

$ant test1
test1:
     [echo] small
     [echo] notifyAll
     [echo] function notifyAll() {/*

迭代getProperties（）的结果的正确方法是什么？

任何建议都非常适用

EDIT2：

jbeard4有一个很好的解释here。关于javascript问题。所以正确的方法是

<script language="javascript"> <![CDATA[
  properties = project.getUserProperties()
  var keyIter = properties.keySet().iterator();
  while(keyIter.hasNext()) {
    var key = keyIter.next();
    var value = properties.get(key);
    echo.setMessage(key+value);
    echo.perform();
  }
]]> </script>

Answer 1

我认为只有使用自定义script代码才能实现这一目标。

请参阅示例Is it possible to call ant task from a javascript scriptdef task?。

只需迭代project.getProperties()并添加exec args through API。

如何迭代ant属性并将其作为arg传递给exec
