org.codehaus.mojo:properties-maven-plugin `set-system-properties` goal compatibility

[PayBas]

http://www.mojohaus.org/properties-maven-plugin/usage.html has a goal called set-system-properties which can be used to set (you guessed it) system properties (as opposed to Maven properties) for specific Maven projects.

I use it to silence some particularly spammy Maven plugins which don't offer built-in verbosity options:

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>set-system-properties</goal>
                    </goals>
                    <configuration>
                        <properties>
                            <property>
                                <name>org.slf4j.simpleLogger.log.io.swagger.codegen.v3.AbstractGenerator</name>
                                <value>warn</value>
                            </property>
                            <property>
                                <name>org.slf4j.simpleLogger.log.io.swagger.codegen.v3.generators.DefaultCodegenConfig</name>
                                <value>error</value>
                            </property>
                        </properties>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

This works perfectly well with mvn, but doesn't work with mvnd

If I run a build with the -Dorg.slf4j.simpleLogger.showLogName parameter, I can see that it's still the same log-producers.

So either the system properties aren't applied, or the way mvnd collects the logs results in strange behavior.

http://www.mojohaus.org/properties-maven-plugin/set-system-properties-mojo.html explicitly mentions:

The goal is thread-safe and supports parallel builds.

So I'm guessing this is a mvnd issue.

Does this happen also with a freshly started daemon? - i.e. after mvnd --stop?

[PayBas]

@ppalaga indeed when I run:

mvnd --stop
mvnd clean install -pl :the-offending-module

It works properly.

If I subsequently run:

mvnd clean install -pl :the-offending-module

The spamming starts again.

Curious

I resorted to just including the following in my project's .mvn/maven.config:

-Dorg.slf4j.simpleLogger.log.io.swagger.codegen.v3.AbstractGenerator=warn
-Dorg.slf4j.simpleLogger.log.io.swagger.codegen.v3.generators.DefaultCodegenConfig=error

Because this issue was driving me insane.
