I have found this solution on stackoverflow. Warning - Build path specifies execution environment J2SE-1.4

I am getting almost the same problem but instead of 1-4 i am having 1-6. Unfortunately I don't really understand this configuration thing. It's new thing to me. I am trying second answer to get this working. I found this pom.xml in src under my project and it's xml looks like this: 

<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">

                </configuration>
            </plugin>

            <!-- Eclipse plugin to force download of source and JavaDoc jars -->

            <plugin>

                    <downloadJavadocs>true</downloadJavadocs>
                </configuration>
            </plugin>
        </plugins>



    </build>
</project>

What and where should I add sth? I am using Eclipse on Windows 7. My version of java is: 1.8.0.25-b18 Words like plugin and Maven and JUnit are highlighted red. I would be grateful for help!

Try

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>2.3.2</version>
   <configuration>
      <source>1.4</source>
      <target>1.4</target>
   </configuration>
</plugin>

And then regenerate the Eclipse project with mvn eclipse:eclipse.
