Here are the updates I'm offered:
Here's me looking for Matrix Project Plugin:
And Script Security Plugin:
Is this about the "Plugin" suffix that's inconsistently stripped?
Really not sure what to do about this.
There are two components involved here, core and the update site, which independently attempt to strip redundant parts out of plugin names.
The server side is (mostly) at https://github.com/jenkins-infra/update-center2/blob/b82c5dac759a868042e9b3c42b017bdc0bda40ae/src/main/java/org/jvnet/hudson/update_center/Plugin.java#L395-L403 with some particularly bad examples at https://github.com/jenkins-infra/update-center2/blob/ef26174817aad3cd838ba188a97374fad3cf7567/src/test/java/org/jvnet/hudson/update_center/PluginTest.java
While client side we only do https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/PluginWrapper.java#L437
I like the aggressive approach a lot better because the results are cleaner, even if the results are not always great in case of really insane plugin names. It is however not an approach well suited for software that gets published and used indefinitely on new inputs.
