Tried to run a very simple (print "helloWorld") script. Runs fine using groovy compiler, groovysh, but throws exception when trying to run as standalone script.
Script, exception, compiler output, script output, env and groovysh output below:

% cat helloWorld
#!/usr/bin/env groovy
print "helloWorld"

% ./helloWorld
Exception in thread "main" java.lang.ClassFormatError: (Illegal Class name "")

The problem is that your file has no extension on it. Even adding a "." on the end of the filename would work. Somewhere in the code it expects the filename to have an extension, and if it doesn't, it won't handle this condition. I tried to find it, but failed as it went deep into the bowels of the compiler. Someone else want to take a crack at it?

This is yet another example documented on the web site that DOES NOT WORK!!

There's a mandatory extension for groovy source files.

This is indeed a bug and the issue should not be closed.
The problem is a leading "./" when the executed script is in the current working directory.

Consider the "Hello World" example at http://groovy.codehaus.org/Running.

> #!/usr/bin/env groovy
> println("Hello world")
> for (a in this.args) { > println("Argument: " + a) > }

When executed as "groovy helloWorld", everything is fine.

When executed as "groovy ./helloWorld", the exception occurs:

I think it is not reasonable to assume that a file name has an extension in order to be used with a relative path.

Updating this issue to be the marker for a problem that affects relative path usage but not absolute path usage for executing scripts.

Kicking this bug since it is a bug and it will affect all non-Windows users who write scripts – since not having extensions on a file name is standard procedure.

If we want to close this one and reopen GROOVY-2081 instead as the marker for this problem, then that is fine.

I think this issue is solved but I don't have sufficient environments/platforms to test it on to be doubly sure. It appears that the need for an extension was removed some time ago but that in some unix environments there was a space being added to the script filename during command line parsing. I plan to mark this issue as closed in the coming days if I receive no further feedback.

This appears to be fixed in 1.5.1, based on a quick check ...

The script: 
#! /usr/bin/env groovy
// -*- mode:groovy encoding:UTF-8 -*-

println ( 'Hello World' )

stored in a file GROOVY_569, without an extension and with the execute bit set, certainly executes fine on Ubuntu with Groovy Subversion HEAD as at 2008-01-18 using the commands:

GROOVY_569
./GROOVY_569
/home/users/russel/Progs/OddsByLanguage/Groovy/GROOVY_569

There is a sever problem with the command line:

../Groovy/GROOVY_569

but this is the bug reported as GROOVY-2081 so I have reopened that bug. It seems it is right to have this bug marked as fixed and closed.
