  • setting web.xml version 2.5
  • setting eclipse jre java 7 (in run configurations > jre > execution environment: javase-1.7)

  • adding following pom.xml:

    <plugin>     <groupid>org.apache.maven.plugins</groupid>     <artifactid>maven-compiler-plugin</artifactid>     <version>3.5.1</version>     <configuration>         <source>1.7</source>         <target>1.7</target>     </configuration> </plugin>
