How to handle required Java version?

fletchowns · January 14, 2015, 2:15am

Nexus cookbook https://github.com/RiotGamesCookbooks/nexus-cookbook
leverages the Java cookbook https://github.com/agileorbit-cookbooks/java,
but Nexus requires at least Java 7.

I came across this code & comment
https://github.com/RiotGamesCookbooks/nexus-cookbook/issues/41#issuecomment-22027060
and while it worked, they didn’t seem happy with the solution.

I’m curious if there’s a better way to handle this scenario?

Thanks!
Greg

We use the Java cookbook all the time, and this, in your cookbook’s attributes/default.rb should be sufficient (works well for us):

default[‘java’][‘install_flavor’] = 'oracle’
default[‘java’][‘jdk_version’] = '7’
default[‘java’][‘oracle’][‘accept_oracle_download_terms’] = true

You’ll need to also include_recipe ‘java’ in your recipe somewhere as well, but that’s all that should be needed.

Of course, change the values to suit, and you don’t need the node[‘java’][‘oracle’][‘accept_oracle_download_terms’] attribute if you’re not using Oracle’s JDK.

This is how the Java cookbook is designed to work, and we have no trouble at all using it this way.

Thanks Jeff. It seems like that's how they thought it should work, but they
also had to duplicate that logic from the java cookbook to set the
java_home and openjdk_packages attributes, because of the way attributes
are loaded. Are you saying that is unnecessary?

As far as I’m aware, yes, that’s unnecessary. We’ve not had any difficulty ourselves, but, as always, YMMV.
