  • 0

I’m developing a project using Maven. After a while i did “update Project Configuration” within my IDE (Springsource Tool Suite). Now my IDE is complaining, that there are some errors, that have not been here before.
The curious thing is, that the error messages seem to be wrong. In the below code it says, that I have to remove the @override Annotation, because a superclass has to be overriden (which i’m actually doing?)

 package org.powertac.humanbroker.services;

        import javax.jms.JMSException;
        import javax.jms.Message;
        import javax.jms.MessageListener;
        import javax.jms.TextMessage;            
        import org.slf4j.Logger;
        import org.slf4j.LoggerFactory;

    public class JMSMessageListenerDecorator  implements MessageListener{

        private static final Logger Log =     LoggerFactory.getLogger(JMSMessageListenerDecorator.class);
        private BaseMessageListener messageListener = null;

        public JMSMessageListenerDecorator(BaseMessageListener l){
            messageListener = l;
        }

        @Override
        public void onMessage(Message message) {

            if (message instanceof TextMessage) {
                try {                               
                    if(Log.isDebugEnabled())
                        Log.debug("Received message "+ message.toString()+" from JMS.");

                    messageListener.onMessage(((TextMessage) message).getText());
                } catch (Exception e){ 
                    Log.error ("The original message leading up to the exception reads ${message.text}.", e);
                }
            } else {
                Log.error ("The JMS Listener knows only how to react to TextMessage objects.");
            }

        }

    }

error message

Any Idea what I could do the make the error messages vanish? Thx

PS: I got about 5 error messages in 3 different classes and all complain about the @Override Annotation.

    In your pom.xml, you’ll want something like this:

    <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
    </plugins>
</build>

    Your current pom.xml is likely configuring your project for Java 5 (probably by default), where you are using Java 6’s language semantics. If you configure everything to be for Java 6, you should be all set.
