GGTS 3.1 Groovy Logging Issue

[pjc42]

I have a compile error using a very basic example of groovy.util.logging

Running this code as a Groovy Script:

import groovy.util.logging.*

@Log4j("logger")
class Car {
	Car() {
		logger.info 'Car constructed'
	}
}

def c = new Car()

gives the following compile error in GGTS 3.1 in Eclipse 3.8

The example in Groovy docs at: http://groovy.codehaus.org/Logging

import groovy.util.logging.*

@Log("logger")
class Car {
	Car() {
		logger.info 'Car constructed'
	}
}

def c = new Car()

does work but as soon as I try to use Log4j it fails to compile.

log4j-1.2.17.jar is on the build path for this project and other groovy scripts in the same project which call log4j using java api work fine.

Any help with what I am missing would be appreciated, many thanks.

Please update to the latest groovy-eclipse using this update site:

http://dist.springsource.org/release/GRECLIPSE/e4.2/

Looks like you are hitting this bug:
https://jira.codehaus.org/browse/GRECLIPSE-1503

Trying this script myself and it is working for me, so it is likely already fixed.

Thanks. I did try updating with http://dist.springsource.org/release/GRECLIPSE/e4.2/ but problem persisted. I have been trying all sorts of plugins and eclipse settings out so assumed as you had it working it was in some other setting I had. I started with a new install of eclipse 3.8 (without the GGTS this time) and it worked as expected. I haven't tried back in a clean GGTS 3.8 but assume it would work also.

Thanks for your help.

Thanks for getting back to me on this. I can't explain this, but I'm glad it is working for you.
