我在让我的 Ant 脚本(用于 BlackBerry 构建(运行 preverify.exe 命令并向其传递正确的参数时遇到问题。
在命令提示符 (Windows 7( 中，这 100% 有效 - 给定的参数正常工作：
preverify -verbose -classpath C:developmenttoolsbb-jdejde5.0componentslibnet_rim_api.jar -d buildclassespreverified buildclassespreverified buildclassesunverified
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:developmenttoolsbb-jdejde5.0componentslibnet_rim_api.jar" />
<arg value="-d buildclassespreverified" />
<arg value="buildclassesunverified" />
</exec>
</target>
这行不通。我收到以下错误：
Illegal option
-classpath C:developmenttoolsbb-jdejde5.0componentslibnet_rim_api.jar
- 从命令行中完全可以接受此类路径(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 向此命令发送正确的参数，就像在命令行版本中一样？我
一定缺少exec什么？以下是以详细模式运行此目标的完整 Ant 输出(如果有帮助(：

这看起来不像是 ANT 问题。预验证命令返回错误消息，证明 ANT 正在执行它...
我不明白这个命令应该做什么，但是使用消息给出了关于根本原因的提示：
[exec] Usage: preverify [options] classnames|dirnames ... [exec] [exec] where options include: [exec] -classpath <directories separated by ';'> [exec] Directories in which to look for classes
您尚未将目录列表指定为"类路径"参数。您已经提供了一个 jar 文件。该命令是否能够支持 jar 文件？
传递参数的方式不正确。不允许在 -classpath 标记和 JAR 名称之间留空格。
您必须将该行(及其下方的-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:developmenttoolsbb-jdejde5.0componentslibnet_rim_api.jar" />
<!-- destination folder -->
<arg value="-d" />
<arg value="buildclassespreverified" />
<!-- source folder -->
<arg value="buildclassesunverified" />
</exec>
我通过在环境变量 PATH 中包含 jdk\bin 目录路径来解决这个问题。
