使用Salesforce ant迁移工具时使用ant-contrib-1.0b3.jar时出现问题

我相信我已正确设置了所有内容，但在运行调用ANT迁移可执行文件的Powershell脚本时，出现以下错误：

我不确定问题发生在哪里。我将ant-contrib-1.0b3.jar文件放入以下目录：C:\apache-ant-1.10.2\lib，但这似乎无法解决问题。

这取决于您的ant版本。 您的ant contrib文件可能与正在运行的ant版本不兼容

我有一个类似的错误，它是通过使用ant-contrib-1.0b1.jar解决的。下载并解压缩它以找到其中的.jar文件

我运行的ant版本是1.10.3

此外，您还可以尝试将其添加到build.xml文件中：

<project name="Sample usage of Salesforce Ant tasks" default="test" basedir="." xmlns:sf="antlib:com.salesforce">
    <taskdef resource="net/sf/antcontrib/antlib.xml"/>

希望这有帮助

对钱德拉尼没有影响。还是一样的问题。我正在运行v1.10.2。有人擦掉了他的ANT安装，然后重新安装，让它正常工作。那会有帮助吗？
