Lombok @Log and @Slf4j not have error method

I want to use Lombok @Log or @Slf4j but when I create:

@Log
public class Test{
    public Test(){
       log.error("Something's wrong here");
    }
}

in log, I do not have got an error method. I have info and warning

I have only log() method.

I tried to add mave dependency to Slf4j library, but it did not help.

An SLF4J implementation needs to be present in classpath. I added Logback :

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.5.5</version>
</dependency>

Lombok's @Log annotation inserts

private static final java.util.logging.Logger log = ...;

See the javadoc of java.util.logging.Logger.
You are right, it has no error(String msg) method. But it has a severe(String msg) method and a throwing(String, String, Throwable) doing what you want.
