Spring MVC tutorial project does not build on IntelliJ

Question

I am trying to build and run a Spring MVC beginner lesson project using IntelliJ. I imported the existing project from GitHub. But when I try to build the project I keep getting:

Error:(3, 38) java: package org.springframework.stereotype does not exist
Error:(4, 47) java: package org.springframework.web.bind.annotation does not exist

These external dependencies jars are under my Maven local repositories (C:\\Users\\sudi.m2)and I can see in IntelliJ under Maven->Repositories that repo location is indeed there. I also tried "Invalidate Cache and restart" but that does not help. My M2_HOME is set correctly to C:\\apache-maven-3.2.2. If I try to run mvn install from command line, I get:

[INFO] BUILD FAILURE

Any suggestions are appreciated.

Answer 1

If the project doesn't have a web.xml file (IE: Entirely java config based). The build war plugin will fail unless you specify the "failOnMissingWebXml" attribute to false.

Answer 2

Delete you local .m2 repository and let it re-download all needed jars. Maybe, there were issues while downloading one of the dependencies.
