Answer 1

Jenkins plugins are dependent on Jenkins LTS versions in use. Best way is while installing the Jenkins take latest (but stable) version of plugins.

Since you are using 1.176 version and trying to upgrade the plugins, the latest plugins do not support the older version of Jenkins (since Jenkins follow Parallel incremental development). You can resolve the problem in 2 ways.

1. Downgrade the plugins and keep the LTS Jenkins version as it is. (not preferred solution since you will not be able to use latest functionality of the plugins and using old plugins is not secured).

• Downgrade of plugins will also be suggested by Manage Jenkins --> Manage Plugins --> Installed

2. Upgrade Jenkins version (LTS 2.24x.x)

• It is time taking option, but if you are heavely using jenkins for your work it is more suggested to upgrade the version. Besides new plugins have more secured and vast functionalities.
• You can check the Changelog and can decided which version is good for you.
• Take a reference of Upgrading Jenkins link.

To understand plugins and Jenkins LTS version dependency, use Jenkins wiki(Confluence Page).

e.g. Pipeline:Node and Processes plugin wiki indicates that for version 2.29 you need to have Jenkins version 1.150.1 or higher.

Note: Latest Jenkins version supports HTTPS instead of HTTP URL for advanced proxy options under Manager Jenkins.
