不能使用Ant的preverify.exe任务运行“<exec>”

Question

我很难让我的Ant脚本(用于BlackBerry构建)运行preverify.exe命令&将正确的参数传递给它。

在命令提示符(Windows 7)中，这是100%工作的--给定的参数正常工作：

preverify -verbose -classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar -d build\classes\preverified build\classes\preverified build\classes\unverified

我尝试使用以下目标将其放入Ant脚本中--尝试使用相同的参数：

<target name="preverify">
    <mkdir dir="${dest.dir}/classes/preverified" />
    <exec executable="${jde.home}/bin/preverify">
        <arg value="-verbose" />
        <arg value="-classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar" />
        <arg value="-d build\classes\preverified" />
        <arg value="build\classes\unverified" />
    </exec>
</target>

这是不起作用的。I得到以下错误：

Illegal option 
-classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar

• 这个类路径在命令行中是完全可以接受的(通常java命令接受JAR文件作为目录，因为它们基本上是ZIP文件)。

如何才能让Ant向这个命令发送正确的参数，就像在命令行版本中一样？，一定有关于exec的东西，我遗漏了什么？

下面是在详细模式下运行此目标的完整Ant输出，如果有帮助的话：

Answer 1

传递参数的方式是不正确的。-classpath标记和JAR名称之间的空格是不允许的。

您必须将这一行(以及它下面的-d )拆分为2行。这样做是可行的：

    <exec executable="${jde.home}/bin/preverify">
        <arg value="-verbose" />
        <!-- classpath to the RIM api -->
        <arg value="-classpath" />
        <arg value="C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar" />
        <!-- destination folder -->
        <arg value="-d" />
        <arg value="build\classes\preverified" />
        <!-- source folder -->
        <arg value="build\classes\unverified" />
    </exec>

Answer 2

这看起来不像是蚂蚁的问题。错误消息由预验证命令返回，证明ANT正在执行.

我不明白这个命令应该做什么，但是使用消息给出了一个关于根本原因的提示：

exec用法:预验证选项，类名，目录名.其中的选项包括: exec -classpath <目录，由';'> exec目录分隔，其中查找类

您尚未将目录列表指定为“类路径”参数.你提供了一个jar文件。命令是否支持jar文件？

我通过在环境变量路径中包含jdk\bin目录路径来解决这个问题。
