Re: antrun plugin - GWT - add the source directory to the classpath [resolved]

[Bernard Lupin <be...@yahoo.fr>]

Please excuse me Nicolas, I was certainly speaking about another maven
plugin, I'll try your link asap.

Returning to my initial problem, I've found a solution to add a directory to
the maven dependencies, which could be useful for other purposes.

The key is to use the <systemPath> available inside the <dependency> tag. So
here is my antrun plugin configuration :

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-antrun-plugin</artifactId>
				<dependencies>
					<!-- ant task for GWT compilation -->
					<dependency>
						<groupId>
							com.company.gwt.tools
						</groupId>
						<artifactId>ant-compile</artifactId>
						<version>1.0</version>
						<scope>compile</scope>
					</dependency>
					<!-- The java sources must be in the classpath -->
					<!-- Group id and artifact id are not important -->
					<!-- ${project.build.sourceDirectory} is unknown here -->
					<dependency>
						<groupId>com.company.project</groupId>
						<artifactId>gwt-exemple</artifactId>
						<version>1.0</version>
						<scope>system</scope>
						<systemPath>src/main/java</systemPath>
					</dependency>
				</dependencies>
				<executions>
					<execution>
						<phase>process-classes</phase>
						<goals>
							<goal>run</goal>
						</goals>
						<configuration>
							<tasks>
								<taskdef name="gwtcompile"
									classname="dk.contix.ant.gwt.GWTCompileTask" />
								<echo
									message="Launching GWT compilation for ${project.name}" />
								<gwtcompile
									destdir="src/main/webapp"
									optimize="true" verbose="false" style="obfuscated">
									<fileset
										dir="${project.build.sourceDirectory}">
										<include name="**/*.gwt.xml" />
									</fileset>
								</gwtcompile>
							</tasks>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
