Feature for maven-build-helper

[Lonzak]

We use the maven-build-helper plugin to add generated source- and test folders to the eclipse build path.

E.g.

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>add-source</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>add-source</goal>
                        </goals>
                        <configuration>
                            <sources>
                                <source>${project.build.directory}/generated-sources/annotations</source>
                            </sources>
                        </configuration>
                    </execution>
                </executions>
</plugin>

This is working perfectly except for one thing:
In eclipse there is the possibity to set the warnings/errors for those generated source folders to ignore. The option is called "Ignore optional compile problems".
We have quite a huge maven multimodule projects and each developer has to go through each generated folder (~50) and set it to ignore. This is quite cumbersome since from time to time this has to be done again (e.g. for a new Branch which requireres a new workspace)

So now I had the idea if the maven-build-helper plugin could be extended with an attribut / tag where this kind of information would be "transfered" - eclipse could be adapted to set this option.
It could possibly look like this but its just an example - the naming and location of this attribute can be different since it proably be has to be generalized....

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>add-source</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>add-source</goal>
                        </goals>
                        <configuration>
                            <sources>
                                <source>${project.build.directory}/generated-sources/annotations</source>
                            </sources>
                            <ignoreFolderProblems>true</ignoreFolderProblems>
                        </configuration>
                    </execution>
                </executions>
</plugin>

Now I am interessted in your opinions - could someting like that be feasible?

Due to the lack of answers  - is this the right place to ask such a question? Or is there some other forum?
Thanks!

My 0.01 on this: modifying Eclipse project files from a generic Maven
plugin does not seem like the right thing to do.

Ignoring optional compile errors ends up in the .classpath file of the
respective project:

<classpathentry kind=3D"src" output=3D"target/classes"
path=3D"target/generated-sources/xjc">
<attributes>
<attribute name=3D"ignore_optional_problems" value=3D"true"/>
<attribute name=3D"optional" value=3D"true"/>
<attribute name=3D"maven.pomderived" value=3D"true"/>
</attributes>
</classpathentry>

I only have a hand full of projects where I use this setting so manual
setup is OK. Your case smells more like a separate tool that modifies
the XML inside the .classpath files ...
