Logging in Cargo Plugin

I have this configuration in my build

local {
        homeDir = file('/opt/tomcat')
        outputFile = file('build/output.log')
        timeout = 60000
          containerProperties {
            property 'cargo.tomcat.ajp.port', 9099
        }
    }

But when i remove “outputFile” logging does not appear in Eclipse Console. What can i do?
