Is there a way to bind an external build command to an eclipse clean action?
If this helps, I use:
In the section "Project properties" → Maven → Life cycle display, you can configure what goals should be run AFTER clean work in this project
In general, you can connect any external tool that will be called during a certain event in the assembly life cycle by going to the "Project Properties" → "Builders" page. There you can identify a new tool and indicate when it should work.
