Re: Jenkins git plugin using only Java 7.1

[Mark Waite]

The Jenkins platform special interest group in gitter might also have 
people with related interests, in case you want to try posting your 
question there.

https://gitter.im/jenkinsci/platform-sig

I've not seen any discussions on this topic in the platform-sig, but there 
have been discussions about mainframe support and about multi-platform 
support for Docker images.

Re: Jenkins git plugin using only Java 7.1

Git plugin 3.9.x does not mandate Java 8 of itself.  The git plugin 3.9.x
compile environment checks that the generated byte code is only Java 7.
However, as you have discovered, that does not check that all its
dependencies only require Java 7.

I think you're stuck performing a search through the git plugin history to
locate a version that does not include any dependencies on a Java 8
component.

[Rich Stephens]

No, that’s not what I was implying, unfortunately.

I was telling about actually running Jenkins itself using Java  7 and trying to 
install the git plugin.

Re: Jenkins git plugin using only Java 7.1

[Rich Stephens]

Yes I’m aware that Jenkins moved on to Java 8 long ago,
But because of the environment I’m using, I’m restricted to going no higher 
than Java 7.

I was afraid the answer would be what you are saying, but thanks for the 
information.

Re: Jenkins git plugin using only Java 7.1

[Baptiste Mathus]

I _think_ you're implying that you're using Java 7 on the agent side (AIX)
and you're running the master on Java 8.
If so, do not do it. It is not supported at all, and will cause issues.
Issues like, well, these ones if I understand your question.

Switch your master instance to running Java 7 and everything should be good.

Side note: I could check with my past colleagues (not in that company
anymore), but pretty sure I was able to run Java 8 on AIX 6.x in the past.
So possibly this isn't the official version, but should be doable.

Sounds like you may be running a rather old Jenkins master. Jenkins has
entirely moved to JDK8 as of about two years ago:
https://jenkins.io/blog/2017/04/10/jenkins-has-upgraded-to-java-8/

Trying to dig up older trees of dependency graphs would be a manual process
unfortunately.

Jenkins git plugin using only Java 7.1

[Rich Stephens]

I have a machine that it limited to no higher than Java 7.1. (It's an AIX 
6.1 machine)  I am running Jenkins 1.6.4.9 for this reason.

I can get Jenkins running fine, but when I try to install the git plugin, 
it installs dependencies that require Java 1.8.

I cannot find any information on specifically which plugin dependencies are 
requiring Java 1.8 or not.

IS there a version of the git (and, by dependency, git-client) plugin that 
will work with Java 1.7?

If so, How can I get ahold of it and ONLY those versions of the 
dependencies that are java 1.7 compatible?
