Issue
I got this error below while trying to clean server workspace. Most actions from server menu in servers views were greyed.
The state of the tomcat v9.0 at localhost is in transition or unknown. Try again when the server has reached a stable state.
I found nothing about this while Googling the error.
Restarting Eclipse solved the issue.
How do you refresh server state from eclipse without restarting Eclispe (which takes some time) ?
Solution
You switch to Intellij IDEA :(
