  Regular expression for names of modules in the module path which depend on the jmod being created, and which should have hashes generated for them and included in the new jmod.
`resolveByDefault`
  Boolean indicating whether the jmod should be one of the default resolved modules in an application. Default is true.
`moduleWarnings`
  Whether to emit warnings when resolving modules which are not recommended for use. Comma-separated list of one of more of the following:
  `deprecated`
    Warn if module is deprecated
  `leaving`
    Warn if module is deprecated for removal
  `incubating`
