groovy

I am currently unable to reprodcue that problem. Could you try the cvs version and tell if it still happens there?

I couldn't find instructions to grab my CVS version - any pointers?

use :pserver:anonymous@cvs.groovy.codehaus.org:/cvs/groovy/

It says user not authenicated...

Oh :-/

:pserver:anonymous@cvs.groovy.codehaus.org:/cvs/groovy

The extra slash at the end is causing trouble, somehow...

Argh....

Which JDK / Maven1 are you using to build the source?

I have groovy-core opened in NetBeans as a Maven1 project. But with {JDK5u6, Mustang b83} & {Maven1.0.2, Maven1.1-beta2} I get nothing but NPE upon building:

javax.xml.parsers.FactoryConfigurationError: Provider

In short, Maven won't start doing anything productive.

I have searched on Google and the bug that I've found against Maven is closed as incomplete, and the one against JDK has not been evaluated yet.

So if you can point me to your building environment (or better yet, if you can build a CVS snapshot for me) I'd be grateful.

so, it took me some minutes... use http://dist.codehaus.org/groovy/distributions/groovy-1.0-RC-01-SNAPSHOT-20060601.jar, that is no official version. You can sue the scripts from the jsr-05 distribution, they haven't changed

Thanks very much for taking the trouble!

Reproduced on 1.0 RC1 snapshot.

Test Case that will fail:

class WholeNumber {
WholeNumber() {
}
}

def a = new WholeNumber()

Test Case that will pass (note the small letter w):

class wholeNumber {
wholeNumber() {
}
}

def a = new wholeNumber()

Basically, try any alternative class name other than "WholeNumber" and it will pass.

you know this feeling when you see the trees, but not the forest? Ok, sorry.. this error is known. it shouldn't result in a bug error message, but currently it is correct that you can't ahve a script part and a class part in the same file if the class part has the same name as the script part. The reasons is that both parts are compiled into classes and they would have the same name then. I'm very sorry that I have totally overlooked the "duplicate class declaration" part in the message... This is on my todo list and will be fixed before 1.0

Ah. True.

The source files starts off containing the class definition only, and mid-way through dev I've renamed my class but not the file name.

Then I've decided to be lazy and just type out some quick test codes at the bottom of the page, which also works.

But of course when I finally try to "complete the circle" by renaming the file to match the class I hit straight onto this bug....

Thanks again~

The message is now no longer a "BUG!" message and it contains valuable information that should help to solve this problem.
