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> nicolas de loof-3 wrote: > > Such a suggestion should be made to GWT development team ! > > As the GWT compilation process is complex (read modules XML, find client > code and referenced objets...), there is no simple way to know some > modified > java source file requires a GWT recompilation... > > The javac compiler is also executed on every build but is fine enough not > to > recompile up-to-date classes. > > > The issue I was talking about is that the initial GWT Mojo did not avoid > the > GWTCompiler to System.exit() during the build.
