我知道，Ant不再流行，但是我们仍在使用它。我想从Ant调用setheaderfooter任务。不幸的是，我无法到达那里。
首先，我成功运行了以下命令，从命令行测试了它的工作原理：
C:\tools\sejda-console-3.2.66-bin\sejda-console-3.2.66\bin>sejda-console.bat setheaderfooter -f c:\Temp\test.pdf -o c:\temp\out.pdf -s all -y top -x center -t Courier-Bold -l "This publication is under embargo until 3 December 2018, 11:00 UTC" -c #ff0000 --overwrite
接下来，我试图让它在Ant目标中运行，就像这样：

这里的输出是：

由于某些原因，Sejda无法识别setheaderfooter命令，而仅列出帮助信息。错误消息中有此部分
[java] Document root element "sejda", must match DOCTYPE root "null".
[java] Document is invalid: no grammar found.
这对我来说真的没有意义。我从来没有从Ant调用过一个类，仅从jar文件中调用过，所以我不确定如何进一步进行。 ：-/
编辑：感谢@martin_clayton的评论，我将-D参数移到了jvmarg元素上，这使事情向前发展了一些，因为现在错误消息涉及sejda的实际选项：

似乎没有理解arg作为参数。 ：-|此外，它仍然具有有关Document元素“ sejda”的先前错误消息。
编辑：我刚刚测试了（已弃用，或至少“强烈建议避免使用”）<arg line=""/>，并且可以使用！ “概念证明”：
<arg line="setheaderfooter -f c:/temp/test.pdf -o c:/temp/out.pdf -l 'BLAH'"/>
