micronaut-parent parent pom and exec-maven-plugin

[asautins]

Expected Behavior

I am adding some steps to include a react frotend build in my pom.xml file, generally following the example here:

https://www.wissel.net/blog/2021/12/deploying-your-frontend-as-webjar.html

The expected behavior is I add the following rule:

          <execution>
            <id>npm install (clean)</id>
            <goals>
              <goal>exec</goal>
            </goals>
            <phase>pre-clean</phase>
            <configuration>
              <executable>npm</executable>
              <arguments>
                <argument>install</argument>
              </arguments>
            </configuration>
          </execution>

That it runs successfully

Actual Behaviour

The actual behavior is the rule fails. When run with the -X flag I see the following error:

npm ERR! errno -36
npm ERR! ENAMETOOLONG: name too long, open 

It appears the parent pom defines the following

        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <version>${exec-maven-plugin.version}</version>
          <configuration>
            <arguments>
              <argument>-classpath</argument>
              <classpath/>
              <argument>-XX:TieredStopAtLevel=1</argument>
              <argument>-Dcom.sun.management.jmxremote</argument>
              <argument>${exec.mainClass}</argument>
            </arguments>
          </configuration>
        </plugin>

Which seems to add the classpath and additional variables to the end of exec:exec rules.

Steps To Reproduce

execute mvn clean on the following pom will result in a failure.

You need to define your exec-maven-plugin configuration node like this:

<configuration combine.self="override">
