Ant build Fail with Boilerplate Generation and Generator (GWT-Platform)

Question

I have a build.xml that work fine, until I start using boilerplate generation and create a Generator.

Everything works fine in Dev Mode, but, I was unable to generate a war for my application.

I think that is because the gen classes are going to /apt_generated, not /src, and my ant compiles /src, I just don't have any idea about generators.

I'm just trying to make it work, but I can't.

Can someone help me?

My build.xml is just like this:

<property name="version" value="1.0.0-SNAPSHOT"/>
    <property name="gwt.module.name" value="com.test.Test"/>
    <property name="server.resources.name" value="server_resources"/>
    <property name="jar.name" value="test${version}.jar"/>
    <property name="war.name" value="test${version}.war"/>
    <property name="src.dir" location="src"/>
    <property name="server.resources.dir" location="war/${server.resources.name}"/>
    <property name="build.dir" location="build"/>    
    <property name="build.server.resources.dir" location="war/WEB-INF/classes/server_resources"/>        
    <property name="lib.dir" location="war/WEB-INF/lib"/>
    <property name="gwt.client.dir" location="com/test/client"/>

    <path id="project.classpath">        
        <fileset dir="${lib.dir}">
            <include name="**/*.jar"/>
        </fileset>
    </path>  

    <target name="prepare">
        <mkdir dir="${build.dir}"/>
    </target>

    </target>

    <target name="compile" depends="prepare">        
        <javac srcdir="${src.dir}" destdir="${build.dir}">

        </javac>        
    </target>

     </target>

    <target name="jar" depends="compile">

            <!-- Don't wrap any of the client only code into the JAR -->
            <exclude name="${gwt.client.dir}/**/*.class"/>
        </jar>

        </copy>
    </target>    
    <!-- Package the JAR file, Javascript, static resources 
    and external libraries into a WAR file -->
    <target name="war" depends="gwt-compile, jar, copy-resources">
        <war basedir="war" destfile="${war.name}" webxml="war/WEB-INF/web.xml">

                <exclude name="**/gwt-user.jar" />
            </webinf>
        </war>
    </target>    

</project>

The errors:

[javac] D:\CARLOS\workspaces\Test\Test\src\com\test\server\actionhandlers\autenticar\RecuperarSenhaActionHandler.java:50: cannot find symbol
[javac] symbol  : class RecuperarSenhaAction
[javac] location: class com.test.server.actionhandlers.autenticar.RecuperarSenhaActionHandler
[javac]     public void undo(RecuperarSenhaAction arg0, RecuperarSenhaResult arg1, ExecutionContext arg2) throws ActionException

[javac]             SourceWriter sw = composer.createSourceWriter(context, printWriter);
[javac]             ^
[javac] 15 errors

EDIT.

I modify my build.xml, now, I have one more property, <property name="apt_generated.dir" location="apt_generated" />, and my compile target turns in into this:

<target name="compile" depends="prepare">
        <javac destdir="${build.dir}">
            <src location="${src.dir}" />
            <src location="${apt_generated.dir}" />
            <classpath refid="project.classpath" />
        </javac>
    </target>

That "solve" the issue with apt_generated (I think), but I still can't build it because the errors with SourceWriter and javax.validation classes.

Answer 1

Generated classes need to be compiled too. As i don't see any code generation in your example I just assumed the following values.

 <target name="compile" depends="prepare">    
        <-- compile generated classes-->
        <javac srcdir="${apt_generated.dir}" destdir="${build.generated.dir}">
            <classpath refid="project.classpath"/>
        </javac>    

        <-- compile sources -->   
        <javac srcdir="${src.dir}" destdir="${build.dir}">
            <classpath location="${build.generated.dir}"/>
            <classpath refid="project.classpath"/>
        </javac>        
    </target>  

As stated in your comment the generated classes depend on the sources and vice versa, so you need to:

• EITHER split your project, so that all common dependencies are in another project
• OR compile everything together

The second could be accomplished like:

 <target name="compile" depends="prepare">    
     <javac destdir="${build.dir}">
        <src location="${src.dir}" />
        <src location="${apt_generated.dir}" />
        <classpath refid="project.classpath" />
     </javac>   
 </target>  

If anything else misses make sure that:

• the appropriate lib is included in project.classpath (if you are not sure which jar you are missing you can try http://www.findjar.com
• all sources are on either of one src dir
