问题 For a long while we were running our GWT-based application in Eclipse using custom subclasses of com.google.gwt.core.ext.ServletContainerLauncher and com.google.gwt.dev.DevMode. This was to allow us to run our custom (newest) Jetty and, over time, it gave us some other control, i.e. launching the server just a bit differently in Eclipse so as to allow files to be spread around Eclipse projects instead of being where they end up in production. These were effectively displacing/reimplementing
