Developing GWT Applications with Maven

Creating GWT Artifacts (for Maven Repository Administrator)

• pack gwt-dev-(OS Name).jar with library files, then create gwt-dev-(OS Name)-(version).jar archives
  • *.dll (windows)
  • *.jnilib (mac)
  • *.so (linux)
• source:trunk/archive/gwt/dev

• Deploy the archives into the maven repository (It's just a memorandum. Change the file paths according to your machine environment)

  leo@leopardcat:utgb/utgb-core> mvn deploy:deploy-file 
   -Dfile=$(cygpath -w ~/work/utgb/trunk/archive/gwt/dev/gwt-dev-windows-1.4.60.jar ) \
   -DgroupId=com.google.gwt -DartifactId=gwt-dev-windows \
   -Dversion=1.4.60 \
   -Dpackaging=jar 
   -DrepositoryId=utgb -Durl=file://f:/cygwin/home/leo/work/workspace/utgb/maven/artifact 
  

• gwt-dev-(windows,mac,linux).jar and the other dependent libraries will be downloaded from:
  • ​http://www.xerial.org/maven/artifact/com/google/gwt
  • ​http://www.xerial.org/maven/artifact/org/xerial/maven/gwt-ant

Project Settings

• pom.xml
  • use the following setting within build/plugins tag

          <!--  GWT compiler -->
          <plugin>
            <artifactId>maven-antrun-plugin</artifactId>
            <executions>
              <execution>
                <phase>compile</phase>
                <configuration>
                  <tasks>
                    <property name="classpath.compile" refid="maven.compile.classpath" />
                    <property name="gwt.dev" value="${gwt.dev}" />
                    <property name="gwt.jvmargs" value="${gwt.jvmargs}" />
                    <ant antfile="gwt-home/build-gwt.xml">
                      <property name="gwt.module" value="${gwt.module}" />
                      <target name="compile" />
                    </ant>
                  </tasks>
                </configuration>
                <goals>
                  <goal>run</goal>
                </goals>
              </execution>
            </executions>
          </plugin>
    

Behind the scenes

• source:trunk/utgb/utgb-common/pom.xml
• utgb-common's pom.xml contains the following setting, that retrieves gwt-dev libraries.

        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-dependency-plugin</artifactId>
          <executions>
            <execution>
              <id>unpack-gwt-dev</id>
              <phase>generate-sources</phase>
              <goals>
                <goal>unpack</goal>
              </goals>
              <configuration>
                <artifactItems>
                  <artifactItem>

                    <artifactId>${gwt.dev}</artifactId>
                    <version>${gwt.version}</version>
                    <type>jar</type>
                  </artifactItem>
                  <artifactItem>
                    <groupId>org.xerial.maven</groupId>

                    <version>1.0</version>
                    <type>jar</type>
                  </artifactItem>
                </artifactItems>
                <excludes>**/*.pom,META-INF</excludes>
                <outputDirectory>gwt-home</outputDirectory>
              </configuration>
            </execution>
          </executions>
        </plugin>
