我已经下载了dom4j-1.6.1并将其添加到 java 的构建路径中。我也熟悉java.lang.NoClassDefFoundError: org/saxpath/SAXPathException但我不断收到异常。
附上一个片段:
public class Parser {
public static void parse(final String path) throws Exception {
final SAXReader reader = new SAXReader();
final Document document = reader.read(new File(path).toURI().toURL());
if (document == null) return;
List list = document.selectNodes("/");
for (Object o : list)
System.out.println(o);
}
}
当我运行它时,我得到以下堆栈跟踪

任何线索是什么导致错误?
