Can anyone please help me to figure out what went wrong?

PS - I am using IntelliJ Idea 14.1.3

As per request I have shared the error I got when I update the pom.xml as mentioned in answer.

Answer 1

Add this to your Maven's pom.xml (or replace it if you already have the compiler section)

<build>
  <plugins>
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.5</version>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
      </configuration>
    </plugin>
    ...
  </plugins>
  ...
</build>

===Update:=== To Starting Jetty in a different port, update your jetty-maven-plugin to something like this:

  <plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>${jetty.version}</version>
    <configuration>
      <httpConnector>
        <port>8081</port>
      </httpConnector>
    </configuration>
  </plugin>

Answer 2

You have got this error because Maven default is using JDK1.3 for the project compilation or building. Since JDK1.3 is not support annotation, if your project has annotation, you need to configure your Maven to use the latest JDK version.

As suggested above, you need to tell maven to run the latest version of JDK you have.
