Ant -f update_dependencies.xml

I just had a minor problem with running

mb:kotlin> ant -f update_dependencies.xml Buildfile: update_dependencies.xml

  [delete] Deleting directory /Users/petrovic/Projects/kotlin/PluginVerifier
  [mkdir] Created dir: /Users/petrovic/Projects/kotlin/PluginVerifier

/Users/petrovic/Projects/kotlin/update_dependencies.xml:5: The following error occurred while executing this line:
/Users/petrovic/Projects/kotlin/update_dependencies.xml:20: The specified destination is a directory

Total time: 0 seconds

I had a symlink pointing at an Ant 1.7 binary.  I removed it and repointed it at an Ant 1.8 binary, and all is well.

Maybe the file should say “requires Ant 1.8 or higher”?
