Daniel Barclay (Drill/MapR) commented on DRILL-2024:
----------------------------------------------------
I don't think this should dropped ("resolved") at least until {{INSTALL.md}}
tells readers whatever bits they need to know to avoid running into this
problem.
Especially, note that while _this_ case of building the (partial) assembly
requires _doing_ a separate Maven clean operation, the case of running {{mvn
test}} requires doing {{mvn install}} before and *not* doing a intervening
Maven clean operation (because of some dependency between things that isn't yet
captured in the Maven project configuration).
I don't mean that {{INSTALL.md}} needs to explain much about what's going on,
just that it should point out a few dependencies that developers (anyone
building Drill) need to know. These seem to include:
- building the assembly with skipping requires cleaning first
- running {{mvn test}} requires having previously run {{mvn ... install}}
(without cleaning) (for certain (sub)projects )
- running {{mvn test}} on a Debian-based Linux system is likely to require
adjusting {{/etc/hosts}}
