retool sync failed

[tkanng]

retool sync failed, when it downloads honnef.co/go/tools/cmd/megacheck:

retool: downloading honnef.co/go/tools/cmd/megacheck
retool: fatal err: execution error on "go get -d honnef.co/go/tools/cmd/megacheck": package honnef.co/go/tools/cmd/megacheck: cannot find package "honnef.co/go/tools/cmd/megacheck" in any of:
        /usr/local/go/src/honnef.co/go/tools/cmd/megacheck (from $GOROOT)
        /home/tkanng/gopath/src/github.com/pingcap/tidb-operator/_tools/src/honnef.co/go/tools/cmd/megacheck (from $GOPATH)
: failed to 'go get' tool: exit status 1
Makefile:85: recipe for target 'check-setup' failed

I check the latest code of go-tools, and find that there isn't cmd/megacheck any more.

Is it a bug of retool?
:)
