Chatty plugin output

[Ekryd]

Hi,
Thanks for a great plugin!

The output from a normal run of the plugin is very long compared to other Maven plugins. I would prefer it to stay quite quiet, by default, if everything is ok. This is my normal output:

And this is my desired output:

[INFO] Generated 518 mutations Killed 500 (97%)
[INFO] Generated report at /Users/xxxx/Workspace/SortPom/sorter/target/site/xxxx

The rest of the information can be debug/verbose messages or be placed in the actual report.

I am aware that the message 'OpenJDK 64-Bit Server VM warning: Sharing is only supported...' is not part of your plugin. Any tips to remove that message is appreciated :-D

Is there any update on how to make pitest silence the stderrs? I get a lot of them from the mutations being worked on normally and would like a way to turn them on/off when they aren't being looked at.

[Ekryd]

Seriously, stop this chatty nonsense!
Your log output is drowning essential information, I just want to know the result.
For now, I will throw out this plugin because there is a real risk that this plugin drowns important messages from other plugins.

Hi @Ekryd,

I fix for this was merged in a few minutes ago, just before I read your delightful comment. Thank you so much for that.

[Ekryd]

Hi @hcoles !
Sorry for the rude tone, I got the feeling that nothing was happening at all with this issue.
Looking forward to next release to retry it again.
