java - How to get gwt jars version information if it is not available in manifest file? -

i have gwt-user.jar , gwt-dev.jar in application. want know version of gwt jar used in application. looked manifest.mf file inside jar file there no version info available there. so, there other way know version jar files ?

gwt provides information in several ways:

• gwt-dev.jar contains com/google/gwt/dev/about.properties
• you can launch gwt-dev.jar (java -jar gwt-dev.jar, or java -cp gwt-dev.jar com.google.gwt.dev.compiler, , it'll give version information)
• the version available generated js, and/or accessible client code using gwt.getversion()
