exec:java of exec-maven-plugin requires compile scope project dependency to run
Platform: debian 12.10 "bookworm", amd64, java 21.0.4, maven 3.8.7, exec-maven-plugin 3.5.0
If I add the jar file containing the mainClass as a compile scope
dependency on the project:
https://gist.github.com/steinarb/d177a1c1146fedf374608390fbbe4841#file-pom-xml-L119
Then this exec-maven-plugin runs (and does its thing, which is convert
an XSD schema to a Relax-NG XML Notation schema):
https://gist.github.com/steinarb/d177a1c1146fedf374608390fbbe4841#file-pom-xml-L168
But having a compile scope dependency on the project adds
msg-rngconverter as a transitive dependency on the project, and that has
many undesirable effects for me (specifically it becomes a runtime
dependency for the OSGi bundle the pom file is a part of).
So I tried reducing the scope to test, which the exec-maven-plugn
documentation says should be sufficient:
https://www.mojohaus.org/exec-maven-plugin/java-mojo.html
But using test scope for the dependenct gives me this error:
https://gist.github.com/steinarb/d0abfd4c8497ae5c6b5ef4c70001fa7e#file-gistfile1-txt-L25
So I tried following this documentation
https://www.mojohaus.org/exec-maven-plugin/examples/example-exec-using-plugin-dependencies.html
and removed the project dependency and changed the config to this:
https://gist.github.com/steinarb/7521ccc87c2e843aa7ee80f23df24911#file-pom-xml-L163
But that gets the same build error as test scope dependency:
https://gist.github.com/steinarb/956af653af12919e256593ab4688ba98#file-gistfile1-txt-L21
Ideas? Tips? Something wrong in my config?
Thanks!

Using <classpathScope>test</classpathScope> and <scope>test</scope> on
the project dependency worked:

No that's correct. I did not make a gist of that, since what I tried was
just the same as the compile scope one, with <scope> of the depedency
changed.

Ah, no. I did not. I will try with that in place (and a test scope
project dependency).

Yes, that's the only thing that has worked for me so far.

Thanks! You have given me something new to try and I will try that and
report back.

O.k. Looking back I couldn't see any of the gists with a test scope
"msv-rngconverter" – am I missing it? Did you have
<classpathScope>test</classpathScope> in the exec plugin configuration?
You wrote it is working when "msv-rngconverter" is a compile project
dependency.
Sorry, I'm not able to help more – just making sure you're not missing
some more obvious detail.

No, that gave me the same error was when changing the scope to test:
https://gist.github.com/steinarb/7521ccc87c2e843aa7ee80f23df24911#file-pom-xml-L163
Ie. unable to find the mainClass specified.
I have tried both with just adding the dependency as in your example, as
well as with adding executableDependency in the above example (with the
executableDependency it was necessary to have the dependency on the top
level to set the <version>, so I know that something was picked up).

Does it work adding the dependency to the plugin dependencies, instead?
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>3.5.0</version>
<dependencies>
<dependency>
<groupId>net.java.dev.msv</groupId>
<artifactId>msv-rngconverter</artifactId>
<version>2022.7</version>
</dependency>
</dependencies>
<executions>
...
</executions>
</plugin>
