I've been provided with a VM on Linux CentOs7 and using Java 1.8. Because we are using Java 1.8 I have struggles to install R properly. I am able to install R-base just not R-devel:
Error: Package: R-java-devel-3.5.1-1.el7.x86_64 (epel)

I have found several posts relating to working with R on a different version of java in the context of OSX but none using Linux, in my case CentOs7.
Without R-devel I'm unable to install packages.
I found several posts suggesting I do:
sudo R CMD javareconf
Which resulted in this output:

Updating Java configuration in /usr/lib64/R
Done.
However, I still fail to install R-devel after running that snippet.
I've found posts suggesting I change JAVA_HOME but then others warning me not to play around with that, example this one: https://stackoverflow.com/questions/26948777/how-can-i-make-rjava-use-the-newer-version-of-java-on-osx.
What's the prescribed approach here? I've asked my Sys admins if we can use Java 1.7 but they are unable to change it.
