I have faced the similar issue and fixed by copying the missing Jar files in to .M2 Path,
forFor example: if you see the error message as "Missing artifact tws:axis-client:jar:8.7"Missing artifact tws:axis-client:jar:8.7 then you have to download "axis-client-8.7.jar" file and paste the same in to below location will resolve the issue... C
C:\Users\UsernameXXX.m2\repository\tws\axis-client\8.7(Paste axis-client-8.7.jar)....
finally, right click on project->Maven->Update Project...Thats it....
happy coding...
