Plugins should adopt a configuration file. buffalo-plugin.toml.
This file can be given to the plugins system and can contain information such:
The plug-in name
Description
Installation command
Available sub commands
Events listened for
Events thrown
Generator steps to override, etc...
Etc...
buffalo plugins install http://example.com(optional path to file | /buffalo-plug-in.toml) - if a plug-in config is found on the server the command will follow the instructions in the file.
This information will be placed into the applications ./config/buffalo-plugins.toml file for later use with other plug-in commands.
This file can also be used by the toolkit.gobuffalo.io site.
The go.mod file still refers to an older version, which pulls in an older version of golang.org/x/tools which ends up breaking upgrades due to a go-diff rename. AFAIU this is something that should be fixed in go, but until it is, it can be worked around by not having any (indirect) references to renamed or otherwise problematic packages.
Updating the github.com/gobuffalo/release dependency to the latest version should fix (part of) this problem.
To reproduce the problem, try:
(This uses gotip for a clearer error message, but it also happens with regular go 1.11 or 1.12).

When you have the buffalo-no-sqlite binary in your path (that's the default name of the buffalo binary provided in the releases page), any buffalo command takes a long time (at least ~2s).
It seems buffalo-plugins considers it as a plugin (due to the buffalo- prefix), so it calls it with available arg. This leads to infinite recursion, since buffalo-no-sqlite scans for plugins, then calls buffalo-no-sqlite available and so on.
I found it when running some tests on my Linux machine, and the CPU was working hard even without many apps started.
Running just buffalo (without any arg) takes a few seconds in this case, and spawns a lot of short-living-processes, always renewed:
