How to perform ordered tasks in Maven2 build

[Perez Ronen]

Hi,

I am trying to migrate a Java application built by Ant to Maven2. among other 
the build perform the following operations:

1) Running a javadoc doclet to find annotated Java files to be externalize 
later as web services
2) compile a small part of the code for step 3
3) run Axis java2wsdl on the compiled code from step 2
4) produce java code with wsdl2java on the wsdl files from step 3
5) compile the entire code

when trying to "mavenize" the process I can accomplish each task at a time but 
fail to achieve them all in that order.

to demonstrate my pom and not load you with details I'll show the following 
snippet:
<build>
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-javadoc-plugin</artifactId>
        <version>2.6.1</version>
        <executions>
            <execution>
                <id>aggregate</id>
                <phase>generate-sources</phase>
                <goals>
                    <goal>aggregate</goal>
                </goals>
                <configuration>...</configuration>
            </execution>
        </executions>
    </plugin>
        <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.1</version>
        <executions>
            <execution>
                <id>compileWSfiles</id>
                <goals>
                    <goal>compile</goal>
               </goals>
               <phase>generate-sources</phase>
                <configuration>
                    <includes>
                        <!-- include 3 source files -->
                    </includes>
                </configuration>

            </execution>
        </executions>
      </plugin>
          <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>axistools-maven-plugin</artifactId>
        <version>1.3</version>
        <dependencies>
          <dependency>
                <groupId>axis</groupId>
                <artifactId>axis</artifactId>
                <version>1.3</version>
          </dependency>
        </dependencies>
        <executions>
            <execution>
                <id>java2wsdl</id>
                <phase>generate-sources</phase>
                <goals>
                    <goal>java2wsdl</goal>
                </goals>
                <configuration>...</configuration>
            </execution>

             <execution>
                <id>wsdl2java</id>
                <phase>generate-sources</phase>
                <goals>
                       <goal>wsdl2java</goal>
               </goals>
               <configuration>...</configuration>
             </execution>
        </executions>
    </plugin>
</plugins>


I pinned all of the build executions on the generate-sources phase and as far 
as I know they should run in the order they are defined in the pom.

The main problem is that I have no control on the order of things and it is 
obviously important here as every step output is the next step input.

any suggestions?

Thanks, Ronen.
