java -cp gwt-dev.jar com.google.gwt.dev.Compiler
Missing required argument 'module[s]'
Google Web Toolkit 2.3.0
Compiler [-logLevel level] [-workDir dir] [-gen dir] [-style style] [-ea] [-XdisableClassMetadata] [-XdisableCastChecking] [-validateOnly] [-draftCompile] [-optimize level] [-compileReport] [-strict] [-localWorkers count] [-war dir] [-deploy dir] [-extra dir] module[s] 

where 
  -logLevel               The level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL
  -workDir                The compiler's working directory for internal use (must be writeable; defaults to a system temp dir)
  -gen                    Debugging: causes normally-transient generated types to be saved in the specified directory
  -style                  Script output style: OBF[USCATED], PRETTY, or DETAILED (defaults to OBF)
  -ea                     Debugging: causes the compiled output to check assert statements
  -XdisableClassMetadata  EXPERIMENTAL: Disables some java.lang.Class methods (e.g. getName())
  -XdisableCastChecking   EXPERIMENTAL: Disables run-time checking of cast operations
  -validateOnly           Validate all source code, but do not compile
  -draftCompile           Enable faster, but less-optimized, compilations
  -optimize               Sets the optimization level used by the compiler.  0=none 9=maximum.
  -compileReport          Create a compile report that tells the Story of Your Compile
  -strict                 Only succeed if no input files have errors
  -localWorkers           The number of local workers to use when compiling permutations
  -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
and 
  module[s]               Specifies the name(s) of the module(s) to compile
