GWT中*-compile.cmd批处理文件的意思

@java -cp "%~dp0\src;D:/Java/gwt/gwt-windows-1.4.62/gwt-user.jar;D:/Java/gwt/gwt-windows-1.4.62/gwt-dev-windows.jar" com.google.gwt.dev.GWTCompiler -out "%~dp0\www" %* com.sample.myProject.client.DemoClient

1. @表示不显示当前输入的命令。
2. java就不用解释了。
3. %~dp0表示当前目录 所以%~dp0\src表示当前目录下的src子目录
4. -out The directory to write output files into (defaults to current)　输出目录
