Question

我无法获取我的Ant脚本（用于BlackBerry版本）来运行preverify.exe命令＆amp;将正确的参数传递给它。

在命令提示符（Windows 7）中，这100％工作 - 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我的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>

这不起作用。我收到以下错误：

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

这个类路径完全可以从命令行接受（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）。

如何让Ant将正确的参数发送到此命令，就像在命令行版本中一样？必须有一些关于exec的内容我缺少？

以下是以详细模式运行此目标的完整Ant输出（如果有帮助：

Answer 1

这看起来不像ANT问题。 preverify 命令返回错误消息，证明ANT正在执行它......

我不明白这个命令应该做什么，但是使用消息提示了根本原因：

[exec] Usage: preverify [options] classnames|dirnames ...
[exec]
[exec] where options include:
[exec]    -classpath     <directories separated by ';'>
[exec]                   Directories in which to look for classes

您尚未指定目录列表作为“classpath”参数....您已经提供了一个jar文件。该命令是否支持jar文件？

Answer 2

传递参数的方式不正确。不允许-classpath标记和JAR名称之间的空格。

您必须将该行（及其下面的-d）分成2行。这有效：

    <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 3

我通过在环境变量PATH中包含jdk \ bin目录路径解决了这个问题。

无法使用Ant的<exec>任务</exec>运行“preverify.exe”
