packer 1.5.4 build error

[IPv4v6]

Overview of the Issue

When trying to build packer 1.5.4 from source (go get) I'm experiencing the following errors:

I think the issue is that the go get is not respecting the package overrides:

replace git.apache.org/thrift.git => github.com/apache/thrift v0.0.0-20180902110319-2566ecd5d999

replace github.com/gofrs/flock => github.com/azr/flock v0.0.0-20190823144736-958d66434653

replace github.com/zclconf/go-cty => github.com/azr/go-cty v1.1.1-0.20200203143058-28fcda2fe0cc

this issue explains why: golang/go#30354

hi @IPv4v6 thanks for bubbling this up; @jhawk28 thanks adding the link to the respective golang/go issue. This is something to keep an eye for the future if things should change with the Go tooling.

The preferred and tested method for installing from source is to clone the project into $GOPATH/src/github.com/hashicorp, checkout out the respective tag git checkout v1.5.4 and use the make dev command to install the binary.

The forked go-cty pkg in the go.mod file will be removed in #8837 (comment) but you still may want to look into using the preferred method as the continued work in improving HCL support for Packer may result in future replace statements.

Hello there, #9805 removes the last replace call which should help here 🙂 .
