问题描述
这是我关于stackoverflow的第一篇文章。因此，如果我做错了某些事情或违反了一些我不知道的规则，请耐心等待我。
我尝试使用xjc编译器将xsd文件（实际上是两个）编译为一组java类。
对于此任务，我有一个ANT文件，该文件通常可以正常工作。现在，我想使用Xequals和XhashCode插件（根据jaxb2-basics文档）。但是每次我得到一个例外：
[xjc] org.xml.sax.SAXNotSupportedException: FEATURE_SECURE_PROCESSING: Feature can not be set to "false" if security manager is present.
下面是完整的堆栈跟踪。
据我了解（希望正确），正在运行的JVM已设置了安全管理器，并且在xjc进程中将XML选项FEATURE_SECURE_PROCESSING设置为false。
但是我没有找到解决方法。我不知道如何影响此标志或如何禁用安全管理器（最后一个并不是我想要执行的操作）。
我的ant文件如下所示

解决方法
首先，感谢您提供更好的格式！
在此期间，我没有解决问题的根本原因，但我解决了问题。 我尝试使用maven而不是ANT，并且可以直接使用。由于maven从maven Central获得了必需的库，因此libs版本可能有所不同。为了尝试使用ANT，我从这里获得了必要的库 JAXB2-Basic Plugins
我的maven pom.xml是帮助任何可能遇到相同问题的人
