根据该文档为ant xjc任务 -

要同时指定多个外部绑定文件，请使用与fileset具有相同语法的嵌套元素。

"To specify more than one external binding file at the same time, use a nested element, which has the same syntax as fileset."

在gradle中，它看起来像这样：

In gradle it would look like this:

 binding(dir:'src/main/schema'){
    include(name:'A.xjb')
    include(name:'B.xjb')
 }

我认为这也可行：

I think this would also work:

binding(dir:'src/main/schema', includes:'A.xjb,B.xjb')
