Installing Oracle JRE

Question

Currently I'm using this package from the AUR.  I'm trying to install it with:
$ makepkg -s
# pacman -U jre-7.9-1-x86_64.pkg.tar
However, this is returned:
looking for inter-conflicts...
:: jre and jre7-openjdk are in conflict (java-runtime). Remove jre7-openjdk? [y/N] y
:: jre and jre7-openjdk-headless are in conflict (java-runtime-headless). Remove jre7-openjdk-headless? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: jdk7-openjdk: requires jre7-openjdk
Why does it complain about openjdk if I'm trying to install oracle jre?  Thanks for any help!

Answer 1

Had some mess too when I switched from jre7-openjdk and jdk7-openjdk to Oracles jre/jdk a couple of months ago.
Not sure if the jdk7-openjdk will work with Oracles jre and it's PKGBUILD points out jre-openjdk as a dependency.
I would suggest that you install Oracles jdk instead, it provides both jre/jdk and you'll be replacing both openjdk packages
and that should solve the dependency problem for you (between the jdk and jre at least).
When I switched I first removed both jdk7-openjdk and jre7-openjdk, and you are probably in the same spot as I was
then (sitting with a bunch of installed apps that depends on java).
So I used
pacman -Rdd jre7-openjdk
pacman -Rdd jdk7-openjdk
to remove them.
By doing that I "broke" all installed packages that depends on java but since I was going to install the new jre/jdk directly
after that it wouldn't matter anyway (installing the new jre/jdk fixes it again).
Not sure if it's the best way to do it but the idea of first removing all packages that have
a dependency to either the jre or the jdk package and then re-install them again (after installing the new jre/jdk)
didn't sound appealing to me... guess I'm just lazy
