package-plugin gives plugin descriptor name is not valid error

[esegura]

Hi,

I am running java 6, grails 2.0.4, with STS 2.9.2.  I have a grails plugin defined:

class ScCommonGrailsPlugin {
    // the plugin version
    def version = "0.1"
    // the version or versions of Grails the plugin is designed for
    def grailsVersion = "1.3.5 > *"
    // the other plugins this plugin depends on
    def dependsOn = [:]
    // resources that are excluded from plugin packaging
    def pluginExcludes = [
            "grails-app/views/error.gsp"
    ]
....

When I try to run grails package-plugin, I get an error that the plugin descriptor name is not valid: ScCommonGrailsPlugin$1.groovy....

any idea where the $1 is coming from?

| Loading Grails 2.0.4
| Configuring classpath.
| Environment set to development.....
| Packaging Grails application.....
| Error Error executing script PackagePlugin: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
