I'm currently trying to migrate an ant based build to maven and need to
generate some source code. We've got a tool that generates the code from
a load of dtd/xml type files and that needs to be compiled first, before
it's run to generate the source.
I've got the following in my pom -
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<configuration>
<tasks>
<!-- Create the code tool output folder... -->
<mkdir dir="${project.build.directory}/generated-sources/main/codetool"
/>
<!-- Compile the code generation tool... -->
<javac
destdir="${project.build.directory}/generated-sources/main/codetool">
<classpath refid="${maven.compile.classpath}" />
<src path="${project.build.sourceDirectory}" />
<include name="codetool/**" />
<exclude name="com/**" />
</javac>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
I'm doing this in phases, so I'm surrently just trying to get the tool to
be compiled, before adding a bit more to the task to actually run the tool
and generate the source files I need.
When I run the generate-sources lifecycle phase I get the following output -
[INFO] Scanning for projects...

My path and JAVA_HOME are set correctly in my environment. Am I missing
some properties or something...? I would have expected this to just work.
