需要帮助获得蚂蚁撒克逊变换'-？'工作

Question

我在使用 ant 运行 saxon 程序时遇到问题 -? arg。根据我的经验，这在 Linux（Ubuntu 风格）和 Windows 10 上失败。

这是 build.xml 中失败的代码：

 <java classname="net.sf.saxon.Transform" classpath="${saxon.dir}/${saxon.jar};." failonerror="true">
            <arg value="-?" description="help information"/>
        </java>

请注意，这似乎有效：

$ java -cp "java/lib/saxon-he-11.2.jar;java/lib/xmlresolver-4.2.0.jar;java/lib/xmlresolver-4.2.0-data.jar" net.sf.saxon.
Transform '-?'
SaxonJ-HE 11.2 from Saxonica
Usage: see http://www.saxonica.com/documentation/index.html#!using-xsl/commandline
Format: net.sf.saxon.Transform options params
Options available: -? -a -catalog -config -cr -diag -dtd -ea -expand -explain -export -ext -im -init -it -jit -json -l -lib -license -nogo -now -ns -o -opt -or -outval -p -quit -r -relocate -repeat -s -sa -scmin -strip -t -T -target -TB -threads -TJ -Tlevel -Tout -TP -traceout -tree -u -val -versionmsg -warnings -x -xi -xmlversion -xsd -xsdversion -xsiloc -xsl -y --?
Use -XYZ:? for details of option XYZ
Params:
  param=value           Set stylesheet string parameter
  +param=filename       Set stylesheet document parameter
  ?param=expression     Set stylesheet parameter using XPath
  !param=value          Set serialization parameter

典型的堆栈跟踪如下所示：

如果有人能够想出适当的 ant 配置或语法来完成这项工作，那就太酷了。

在 Windows 10 和 Java 20 上发现同样的 bug，解决方案是在 java 命令中添加 fork="yes"。自 Java 18 以来，这一直是一个问题，截至本文发布之日尚未修复。
