Please update github.com/gobuffalo/release dependency

[matthijskooijman]

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).

Thanks for the superfast response, the new version seems to work.

I was tracing another broken dependency path, preparing to report it elsewhere, but it seems that was fixed by this commit as well (the path started with licensor plugin, which circled down into older versions of buffalo-plugins).

To apply this fix, I had to first explicitly upgrade buffalo-plugins using go get -u github.com/gobuffalo/buffalo-plugins, afterwards go get -u -m works as expected again.

Thanks!
