Cannot resolve symbol 'exec'

I am having a strange issue

1. In my pom.xml, I have the following entry

<dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-exec</artifactId>
            <version>1.1</version>
        </dependency>

2. And in my IDE I have the following import
import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.commons.exec.ExecuteWatchdog;

I am getting an error on the 3rd import, which is strange when I compile it in command line, it works fine, but I cannot get the IDE to work which is a pain.

Any help would be appreciated.
