Java 用于OGC模式的Jaxb

这是我的方案（scheme1.xsd）

我明白了：

parsing a schema...
[ERROR] Property "Title" is already defined. Use <jaxb:property> to resolve this conflict.
line 232 of "http://www.w3.org/1999/xlink.xsd"

我使用了这个文件（binding.xjb）：

我做错了什么？

问题是xjc构建的ObjectFactory将包含一个用于包内元素的factory方法，在您的情况下：

在geometryPrimitives.xsd的第1466行：

<element name="_Solid" type="gml:AbstractSolidType" abstract="true" ...
