Intellij Error:Cannot build Artifact 'XXX:war exploded' because it is included into a circular dependency

The solution is to remove "MavenDemo:war" artifact and "MavenDemo:war exploded" artifact from the project, and rebuild the project、rebuild artifacts. set the deployment artifact from MavenDemo:war to MaterialManager:war.

I think the problem of this project is that the "MavenDemo:war" artifact and "MavenDemo:war exploded" artifact are repeated. So the solution is to remove them from the project.

And then, Everytime after I make some update in my code, I can click "Run" Button to deploy the updated project to Tomcat successfully.

Hope it can help somebody else ~
