> CLONE - dash in script filename
> -------------------------------
>
> Key: GROOVY-7670
> URL: https://issues.apache.org/jira/browse/GROOVY-7670
> Project: Groovy
> Issue Type: Bug
> Components: class generator
> Affects Versions: 2.4.5
> Reporter: Christoph Grothaus
> Priority: Minor
> Labels: ClassFormatError
> Attachments: fibonacci-numbers.groovy, fibonacci_numbers.groovy
>
>
> Cannot create script with dash ("-") in filename.
> Please try to run the two attached groovy scripts. The one with an underscore
> in the filename runs happily (don't wonder, it gives no output). The one with
> a dash in the filename gives this error: {noformat}$ groovy
> fibonacci-numbers.groovy
> Caught: java.lang.ClassFormatError: Illegal class name
> "fibonacci-numbers$fib" in class file fibonacci-numbers$fib
> java.lang.ClassFormatError: Illegal class name "fibonacci-numbers$fib" in
> class file fibonacci-numbers$fib
> at fibonacci-numbers.run(fibonacci-numbers.groovy:5){noformat}
> It really took me some time to figure out that the dash was causing this. I
> would like to see Groovy allowing dashes in script filenames. If that should
> be impossible, at least the error message should cleary indicate that I have
> used an illegal character in the script filename.
