gwt-maven-plugin

Build Status

This plugin aims at making it easier to build GWT projects with Maven, by providing two specific packagings: gwt-lib and gwt-app.

Basic usage

  1. Add the plugin to your POM and enable extensions:

    <plugin>
      <groupId>net.ltgt.gwt.maven</groupId>
      <artifactId>gwt-maven-plugin</artifactId>
      <version>…</version>
      <extensions>true</extensions>
    </plugin>
  2. configure your module name in the plugin:

    <configuration>
      <moduleName>com.example.app.App</moduleName>
    </configuration>
  3. set your <packaging> to either gwt-lib or gwt-app

  4. Manage your module in a src/main/module.gwt.xml file.

Features

  • Adds all source roots are resources so they're packaged within the generated JAR.

  • Uses src/main/super for super-sources and possibly relocate them within your module's package with <relocateSuperSource>true</relocateSuperSource>.

  • Generates <inherits> from Maven dependencies: the gwt:generate-module searches for META-INF/gwt/mainModule files in the projects direct dependencies and merges them with an (optional) src/main/module.gwt.xml file.

    The META-INF/gwt/mainModule files are generated by the gwt:generate-module-metadata goal.

  • Imports sources dependencies: dependencies with a <type>java-source</type> are unpacked and added as resources. When building a GWT adapter for a shared library, this allows the library sources to be packaged within the GWT adapter lib, along with the GWT-specific sources, super-sources and GWT module.

  • Packaging gwt-app generates a WAR that can be directly used as overlays in a downstream module with a war packaging.

Documentation

The plugin documentation is published at https://tbroyer.github.io/gwt-maven-plugin/

You can also look at the integration tests, particularly gwt-lib, gwt-app, import-sources and e2e.

You can’t perform that action at this time.
