Václav Kadlčík commented on JBDS-4257:
--------------------------------------

No, I'm afraid you don't understand. The problem is not

"rh-eclipse47-devstudio depends on A and that's bad"

The problem is "reverse":

"rh-eclipse47-devstudio accidentally becomes an unwanted dependency for other RPMs"

It's OK that rh-eclipse47-devstudio depends on rh-eclipse47-base. It isn't OK that *rh-eclipse47-base depends on rh-eclipse47-devstudio*. rh-eclipse47-devstudio creates this problem indirectly by unnecessary "Provides:" items in its RPM header.

Look at rpm -qp --provides rh-eclipse47-devstudio-11.0-0.20170720.0326.el7.x86_64.rpm. That should contain only

* rh-eclipse47-devstudio = 11.0-0.20170720.0326.el7
* rh-eclipse47-devstudio(x86-64) = 11.0-0.20170720.0326.el7

Anything else at this moment is just begging for dependency problems.

> [~vkadlcik] said that it is because rh-eclipse46-devstudio offers some package which rh-eclipse46 needs, so yum decides to use devstudio as library.
> He said that the best practice for end-user application like rh-eclipse46-devstudio is to have less amount of stuff in "rpm -q --provides". Rh-eclipse46 provides 4 packages, devstudio provides 539 packages.
