No. gwt-maven-plugin is a Maven plugin that allows you to easily launch the GWT Compiler or DevMode (and several other tools: I18NSync, etc.) from Maven (configured in your POM). You could do all of that using the maven-antrun-plugin or exec-maven-plugin; gwt-maven-plugin just makes it "more Mavenish". M2Eclipse is an Eclipse plugin to integrate Eclipse with Maven (automatically configure Eclipse projects from Maven POMs, for instance) and the Google Plugin for Eclipse integrates with both of them (when M2Eclipse is present) to automatically configure your Eclipse project with the GWT nature if it finds the gwt-maven-plugin and gwt-user dependency in your POM (so you can use "Run as… Web Application" from within Eclipse, for instance, and benefit from the GWT-RPC interface validation, and several other GWT-specific Eclipse features. > I use eclipse install new software and get the M2Eclipse from following > site: > http://download.eclipse.org/technology/m2e/releases > and my eclipse already installed "Google Plugin for Eclipse", is this > means I already have GWT Maven Plugin? > No. But as with everything with Maven, it'll just be downloaded the first time Maven needs it (when building your project). 2) as stated in > http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.html > there should be ""Goals to run on project import" in eclipse windows > > preferences > maven > but my eclipse has no this option!! > also, what is the setting for?
