This command line does not look very elegant, due to the fact that:

  • we want ${jmh.args} to be split into words.
  • we do not want the classpath to be split into words.

What would you say about passing the classpath in the CLASSPATH environment variable instead:

<environmentVariables>
  <CLASSPATH>target${file.separator}classes${path.separator}target${file.separator}test-classes${path.separator}${test.classpath}</CLASSPATH>
</environmentVariables>

Sure, this seems to work as well. I changed it.

But, I thought that the quotes were already preventing the splitting of the classpath. The JMH args were left unquoted, same as before.

The quotes should work in most normal cases, although I suspect that using " in the path of the Maven local repository on UNIX might break the configuration (the plugin uses plexus-utils to split the command line).
Using the environment variable is probably just safer.
