I'm getting the following error when trying to run hone-maven-plugin the first time:

I believe it's perfectly valid case when we don't have the parallel tool. Can we run hone-maven-plugin even if we don't have this command?

@yegor256 what do you think?

[yegor256]

@volodya-lombrozo yes, we can skip the usage of parallel if it's absent. In such a case all files may be processed sequentially.

[volodya-lombrozo]

@yegor256 ping, I still need it

[yegor256]

@volodya-lombrozo I'll fix it. In the meantime you can avoid this error by setting threads to 1: https://www.objectionary.com/hone-maven-plugin/optimize-mojo.html#threads
