Description of problem:
According to the eclipse.org website at https://eclipse.org/downloads/packages/eclipse-ide-java-developers/marsr ("Detailed feature list") Eclipse for java developers doesn't depend on eclipse-pde to be installed.
However when installing eclipse-jdt 4.4.2 or 4.5.0 on Fedora 22 it pulls in eclipse-pde, eclipse-ecf-core and eclipse-emf-core packages. Those packages pull in a lot of other dependencies and I don't want to install 20+ additional packages I won't need.
ecf-core and emf-core are mandatory deps and they are bundled with every eclipse platform but pde shouldn't be part of this list. To be investigated more.
I see the following packages being installed when i attempt to install 'eclipse-jdt' : http://paste.stg.fedoraproject.org/4916/ . eclipse-pde is not brought in for Fedora 22. Are you doing 'dnf install eclipse' ? It looks like 'eclipse' is actually provided by 'eclipse-pde'  . My guess is we did this in the past because the "Classic" Eclipse used to ship with PDE, and since PDE depended on JDT, which brought in everything else, it made sense.
In case anyone is interested in a bit of history, the first time the 'eclipse' provides was introduced, was in http://pkgs.fedoraproject.org/cgit/eclipse.git/commit/?id=619a6b2f417f5c5a771fa0fcee090c82d4705522 . The sdk package eventually got moved into pde, and so pde inherited the provide. I think since then jdt has
Would it be safe to assume that most users don't want PDE, and so we should really make the JDT provide 'eclipse'.
Consensus seems to be move the provide to JDT, so I did that when making a different update to the package.
