Short description of the issue/suggestion:

How do I configure FileAssociations in gradle?

I write this code：

def association = new FileAssociation()
association.extension = 'log'
association.description = 'log_analyzer'
association.mimeType = 'text/plain'

task packageAppForMac(type: PackageTask, dependsOn: shadowJar) {
    appName = project.name
    platform = 'mac'
    fileAssociations  = [
            association
    ]
}

after run it report that:

Unable to store input properties for task ':packageAppForMac'. Property 'fileAssociations' with value '[FileAssociation [mimeType=text/plain, extension=log, description=log]]' cannot be serialized.
