Yes I know its more common to start with java source files but in this case
that is not possible unless someone knows how to generate sources from a
javassist generated CtClass. If I could do that then yes I could just add
the sources instead of the class.
Here is the best I have so far and sort of works. Since my class generator
writes to the target/classes folder I told the exec-maven-plugin that and
now it is part of the build as other modules can use the generated class
but its not a great solution as my IDE does not know about the class so it
shows errors. So apparently IntelliJ's Maven support does not extend this
sort of exec-maven-plugin configuration. I need to find a better way to do
this so IDE is happy as well.
Here is the relevant part of my pom.
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<executions>
<execution>
<id>code-generator</id>
<phase>compile</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.issinc.odin.display.metadata.generator.UiDisplayMetadataGenerator</mainClass>
<includeProjectDependencies>true</includeProjectDependencies>
<addOutputToClasspath>true</addOutputToClasspath>
<outputDirectory>${project.build.directory}/classes</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
