Rpm Plugin throws exception when using "with [CopySpec]"

[melodious]

The following code throws an exception. This code works seamlessly with copy, jar, zip, tar tasks:

distCopySpec = copySpec {
  into("${project.name}-${version}") {
    with project.distAllBatchCopySpec

    from('src/main/config') {
      fileMode = 0755
      exclude('build.properties')
    }

    into('lib') {
      from(jar.outputs.files)
      from(configurations.addToDist)
    }

    into('logs') {
      fileMode = 777
      from(tempLogDir)
      include("temp.log")
    }
  }
}

task rpm(dependsOn: jar, type: Rpm) {
  baseName = componentName
  destinationDir = distDir
  arch = rpmArchitecture
  os = rpmOs
  release = rel
  group = rpmGroup
  vendor = rpmVendor
  license = rpmLicense

  with distCopySpec
 }

This is the exception:
