I want to use dom4j to parse xml string. But when I add dom4j dependency in pom file, my dev tool(Eeclipse) prompt errors below: enter image description here I tried to refresh project and maven's update project, the errors still occured. If remove the dependency, all of errors disappear, also dom4j cannot use.

Have you tried right clicking on the project and Maven -> Update Project? Every time the pom is changed, this needs to be run. – karen
Yes, I have tried Maven->Update project and also refresh project, but the errors still occur.@karen – Tony
If you have maven installed on your computer try "mvn install" to install any missing packages (further details here – karen
First think is: Try to build your project on plain command line... – khmarbaise

I figured out it through a whole day working, the fix steps are: 1. the first line of errors prompt in eclipse is : fail to read artifact descriptor for xml-apis:xml-apis:jar:1.4.01.(the first capture image of the question) 2. I assumed that something are wrong with xml-apis in maven repository, so I find the directory of xml-apis in maven repository and remove them all 3. After that, I use Maven->Update project in eclipse, the errors run away.

I think the reason is: some files of xml-apis were damaged.
