We are in the process of migrating quite a few Ant based projects to
Maven. Those projects had the requirement to have the same class in 2
jars (for bad technical reasons that I wont explain here). Before we
can actually spend the time needed to clean that up, we did as follow
:
Have all sources for all modules in the parent src folder. Create a
subfolder with a pom.xml for each module. Configure those modules to
fetch their sources from the parent src folder. Configure the
maven-compiler-plugin to include the needed sources in the jar. So
more or less :
project
|-- module1
| \-- pom.xml
|-- module2
| \-- pom.xml
|-- module3
| \-- pom.xml
|-- src
| \-- main
| \-- java
\-- pom.xml
with the module1 pom having some thing like :
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<includes>
<include>**/package/to/include/**</include>
</includes>
</configuration>
</plugin>
This is definitely a dirty hack, but it can be quite flexible ...
