(defaults to ON) -port Specifies the TCP port for the embedded web server (defaults to 8888) -whitelist Allows the user to browse URLs that match the specified regexes (comma or space separated) -blacklist Prevents the user browsing URLs that match the specified regexes (comma or space separated) -logdir Logs to a file in the given directory, as well as graphically -logLevel The level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL -gen Debugging: causes normally-transient generated types to be saved in the specified directory -bindAddress Specifies the bind address for the code server and web server (defaults to 127.0.0.1) -codeServerPort Specifies the TCP port for the code server (defaults to 9997 for classic Dev Mode or 9876 for Super Dev Mode) -[no]superDevMode Runs Super Dev Mode instead of classic Development Mode. (defaults to ON) -server Specify a different embedded web server to run (must implement ServletContainerLauncher) -startupUrl Automatically launches the specified URL -war The directory into which deployable output files will be written (defaults to 'war') -deploy The directory into which deployable but not servable output files will be written (defaults to 'WEB-INF/deploy' under the -war directory/jar, and may be the same as the -extra directory/jar) -extra The directory into which extra files, not intended for deployment, will be written -modulePathPrefix The subdirectory inside the war dir where DevMode will create module directories. (defaults empty for top level) -workDir The compiler's working directory for internal use (must be writeable; defaults to a system temp dir) -XmethodNameDisplayMode Emit extra information allow chrome dev tools to display Java identifiers in many places instead of JavaScript functions. -sourceLevel Specifies Java source level (defaults to auto:1.7) -XjsInteropMode Specifies JsInterop mode, either NONE, JS, or CLOSURE (defaults to NONE) -[no]incremental Compiles faster by reusing data from the previous compile. (defaults to ON) and module[s] Specifies the name(s) of the module(s) to host
