Allow installation of java11 version of nexus

[bgp-sz]

Add optional "nexus_suffix" variable.

Can be set to "java11" to fetch the java11 version instead of the default java8 version starting with 3.76.0

IMHO #417 has a nicer way of handling java8 and java11 versions.

Thanks for the pointer.

I think my way has some upsides as #417 will break downloads for older version (<3.67) and will also likely need further changes in the future.

But as a user either version is fine for me :-)

Any news on this change?

From the newly released version 3.71.0 on Nexus will only support Java17 and the H2 DB.
See https://help.sonatype.com/en/download.html

The corresponding download archive of Nexus has the format https://download.sonatype.com/nexus/3/nexus-3.71.0-06-mac.tgz.

This PR can't handle this new situation and needs to be supplemented to work also with the newest Nexus version.

I would expect setting nexus_suffix to mac should work. Did you try that?

Hi @bgp-sz
thanks for your response.
My last comment was meant to illustrate the fact, that the java version is now vanished again from the download URL.

@bgp-sz that wouldnt work in your code. It would result in the following string:
nexus-3.70.0-mac-unix.tar.gz.

The question is do we want to support this role for macOS targets (and maybe Windows) as well?
I bet there are multiple tasks and modules in this role that would need to be refactored to fully support macOS and/or Windows.

You are right, i didn't read it properly. As you mentioned, this role never supported mac, and I think it's a bit out of scope of this PR. You can always not set nexus_suffix to get the old behaviour of no specific package name back, so it should be safe to merge.
