The type org.xmlpull.v1.XmlPullParser cannot be resolved.

最近在搞微信开发，遇到一个问题，记录下来解决办法与大家分享。

在引用XStream这个类的时候代码：

public static XStream createXstream() {
return new XStream(new XppDriver() {
@Override
public HierarchicalStreamWriter createWriter(Writer out) {
return new PrettyPrintWriter(out) {
boolean cdata = false;
Class targetClass = null;


@Override
public void startNode(String name,
@SuppressWarnings("rawtypes") Class clazz) {
super.startNode(name, clazz);
// 业务处理，对于用XStreamCDATA标记的Field，需要加上CDATA标签
if (!name.equals("xml")) {
cdata = needCDATA(targetClass, name);
} else {
targetClass = clazz;
}
}


@Override
protected void writeText(QuickWriter writer, String text) {
if (cdata) {
writer.write("writer.write(text);
writer.write("]]>");
} else {
writer.write(text);
}
}
};
}
});
}

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！
