danielbeck this may just be a display issue; are you referring to transitive dependences or something else?

... transient dependencies should be installed along with the selected plugins (and they should be visible in the dependency list in the plugin wizard).

kzantow Many plugins started out as part of core Jenkins and were later moved into plugins ("detached"). They're automatically added to the classpath of plugins depending on a version of Jenkins when these were still part of core as to not break those plugins.

List of plugins: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/ClassicPluginStrategy.java#L324
Added to dependencies of plugins depending on old cores: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/ClassicPluginStrategy.java#L313..L320

They're not listed in the update site JSON as dependencies, as they're implied. It requires Jenkins core internals (i.e. that list in ClassicPluginStrategy) to determine whether they need to be considered implied dependencies.

The plugin manager UI treats them as actual dependencies, and does not allow disabling e.g. Matrix Project Plugin while at least one plugin depending on core 1.560 or earlier is still enabled. The setup dialog should do the same (or we need to find another solution to this).

Based on this list, LDAP Plugin (core dependency 1.566) should have a dependency on JUnit Plugin (detached 1.577) in the setup dialog (which would be completely bogus, but whatever…), but it does not.

danielbeck ah yes, this is a larger issue: these plugins also don't have the metadata available to the setup wizard (e.g. junit).

kzantow Right, that probably needs to be fed from ClassicPluginStrategy (and may actually require some reworking there if it is currently only available for already installed plugins).
