我正在尝试通过ant来运行schematron，并且每次尝试使用该文件时 iso_svrl_for_xslt1.xsl，命令ant产生以下消息：
C:\Users\desenvolvedor\Documents\Projetos\XMLPROJECT\schematron-
master\schematron-ant-configuration\schematron-master\tr
unk\ant-schematron\test\ant\build.xml:39:
javax.xml.transform.TransformerFactoryConfigurationError: preprocessor

这是我的github，其中包含用于测试的文件：https://github.com/cpereiramt/schematron-ant-configuration
如果有人可以帮助我，我将不胜感激。
