处理的方法就是
在当前类的第一行（package位置）会提示：Multiple markers at this line
- The type org.xmlpull.v1.XmlPullParser cannot be resolved. It is indirectly referenced from required .class files
- The type org.xmlpull.v1.XmlPullParser cannot be resolved. It is indirectly referenced from required .class files
- The type org.xmlpull.v1.XmlPullParserException cannot be resolved. It is indirectly referenced from
required .class files
这样的信息，这是因为XStream只是一个jar文件，但是它里面会依赖一个jar包，依赖的jar包是：xmlpull_1_0_5.jar、只要把这个jar包引入之后，问题即可解决！
