maven project not recognizing some artifacts

Question

I am new to Maven, It might be stupid question. My problem is I have created dynamic web project in Eclipse Luna version. I have added some artifacts in pom. JAXRS and DOM4J. It downloaded all jars.

I am able to import JAXRS class in my code with out adding jaxrs in lib file. but i am not able to access DOM4J class. I am using web-sphere as my server.

Please help me to fix dom4j issue. Thanks in advance.

If Jar is downloaded as you mentioned then simply do this, in eclipse if you added Maven from Market place then it well and good if not then add this and then

Right click on your Project->Maven->Update the Project

It will resolve the issue related to dependency.

OR

try this command

mvn clean -U

mvn clean install -U

mvn eclipse:eclipse -U

See Maven: The Complete Reference, 6.1.11. Downloading and Verifying Dependencies or mvn --help :

 -U,--update-snapshots Forces a check for missing releases and updated snapshots on remote repositories
