Maven - can't see conflicts

https://youtrack.jetbrains.com/issue/IDEA-153544 may be related. Please share a sample project to reproduce this problem. Thank you.

Even new project with following pom doesn't show the conflicts:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <modelVersion>4.0.0</modelVersion>

   <groupId>g</groupId>
   <artifactId>a</artifactId>
   <version>1.0-SNAPSHOT</version>

   <dependencies>
      <dependency>

         <artifactId>guice</artifactId>

</project>

Can't reproduce in 2016.1.2 EAP (https://confluence.jetbrains.com/display/IDEADEV/IDEA+2016.1+EAP):

I see this: 

I noticed that the conflicts were shown for some maven projects until I reimported them.

Try re-importing with Maven 3.3 or later:

Thank You. It's working.

I have one other problem. For some maven projects named version-SNAPSHOT, it doesn't update dependecies according to changes in pom until I change version in pom e.g. to version-SNAPSHO. It doesn't work with auto-import enabled and also on manual reimport. If I delete everything from the pom beside the groupId, artifactId and version, it still behaves the same way.
