In reviewing this PR: #1137 I found something unexpected...
Although the PR itself was attempting to add arm64 support (aka aarch64); we knew that arm64 was being already being built and released without any code in that script .

I determined that we had a script that was not doing what it was named for...
https://github.com/apache/openwhisk-wskdeploy/blob/master/tools/travis/build_tag_releases.sh

and was not accounted for properly (i.e., removed) when gogradle support was added and then subsequently improved over time.

History

The original support of gogradle was added here (no "build_tag_release.sh):
#812

which removed the script in question:

- export build_file_name=wskdeploy
- go get github.com/inconshreveable/mousetrap
- "./tools/travis/build_tag_releases.sh $build_file_name"
- export RELEASE_PKG_FILE=$(ls $build_file_name-*.*)

later the same day it was added back (with no reason provided):
#814
with the comment/title: "Keep the date update-to-date when the tag latest is updated"

before_deploy:
- export build_file_name=wskdeploy
- go get github.com/inconshreveable/mousetrap
- "./tools/travis/build_tag_releases.sh $build_file_name"
- ./gradlew --console=plain releaseBinaries

Note that:

• This seems like perhaps a failure to rebase after the first PR was merged?
• gradlew is invoked AFTER the bash script
• gradlew has no command line args to set the version/date/commit (yet)
• if we remove the bash script, we can remove the export and "go get" of "mousetrap"

It was specifically removed here "Remove the redundant packages from the release artifacts":
#934

• Before this the Bash script was before gradlew

BUT, then it was explicitly added back here "Add the build_tag_release script back":
#936

• THIS is the PR that added the Bash script AFTER gradlew!!!
• My guess is that was only added back to get the build version added back to the build

Thankfully, Anthony added support for the LDFLAGS here:
https://github.com/apache/openwhisk-wskdeploy/pull/1047/files

LDFLAGS=-ldflags "-X main.Version=${VERSION} -X main.GitCommit=${BUILD} -X main.BuildDate=${BUILD_DATE} -X main.Build=`git rev-parse HEAD` "

which made any part of the very questionable script rendered defunct.
