Maven Struts2 project (org.apache.struts:struts2-archetype-starter) created with some issues in intellij idea 15.0.4 - maven

Question

I created Struts2 project in IntelliJ IDEA 15.0.4(ultimate edition) using maven3 (chose org.apache.struts:struts2-archetype-starter). After creating this project there're some issues like on screens below. I want to notice that I enabled auto-import for maven.
Here's my pom.xml:

How to resolve this problem?

Answer 1

Edit pom.xml and add
<properties>
<struts2.version>2.3.24.1</struts2.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>${struts2.version}</version>
</dependency>
The compilation error points to the missing dependencies in the project configuration. If you are using Maven with IJ you should synchronize Maven configuration with IJ configuration. To let IJ do it automatically you can check box on the notification shown or use project settings.

Answer 2

I've solved this problem. You have to change data in tag <version> in pom.xml. As shows below.
<!-- Logging -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>${log4j2.version}</version>
</dependency>
to
<!-- Logging -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.5</version>
</dependency>
