Idea maven lacks dependencies, project does not lead to MAVEN's jar package problem

At the beginning of the external Libraries in addition to the JDK <1.7> there is no other jar package, I initially looked at a lot of information, some people say that is the MAVEN project eclipse turn to idea when the situation will appear, But finally found that the reason is not, my project has two model, a model need to draw another model, but when the lead did not find the path, so the error parent path problem, all the jar package is not introduced. The way to find the problem is to clean the project, carefully looking at the error among them, the reason is mentioned.

Step Two

So what did I do after I found out why?

1, will need to be cited in the project clean

2. Install again

3, finally reimport the whole project
