Append the package.json version number to my build artifact in aws-codebuild - aws-codebuild

Question

I really dont know if this is a simple (must be), common or complex task.
I have a buildspec.yml file in my codebuild project, and i am trying to append the version written in package.json file to the output artifact.
I have already seen a lot of tutorials that teach how to append the date (not really useful to me), and others that tell me to execute a version.sh file with this
echo $(sed -nr 's/^\s*"version": "([0-9]{1,}.[0-9]{1,}.*)",$/\1/p' package.json)
and set it in a variable (it doesn't work).
i'm ending up with a build folder called: "my-project-$(version.sh)"
codebuild environment uses ubuntu and nodejs
Update (solved):
my version.sh file:
#!/usr/bin/env bash
echo $(sed -nr 's/^\s*\"version": "([0-9]{1,}\.[0-9]{1,}.*)",$/\1/p' package.json)
Then, i just found out 2 things:
Allow access to your version.sh file:
git update-index --add --chmod=+x version.sh
Declare a variable in any phase in buildspec, i dit in in build phase (just to make sure repository is already copied in environment)
TAGG=$($CODEBUILD_SRC_DIR/version.sh)
then reference it in artifact versioned name:
artifacts:
files:
- '**/*'
name: workover-frontend-$TAG
As result, my build artifact's name: myproject-1.0.0

Answer 1

In my case this script do not want to fetch data from package.json. On my local machine it working great but on AWS doesn't. I had to use chmod in different way, because i got message that i don't have right permissions. My buildspec:
version: 0.2
env:
variables:
latestTag: ""
phases:
pre_build:
commands:
- "echo sed version"
- sed --version
build:
commands:
- chmod +x version.sh
- latestTag=$($CODEBUILD_SRC_DIR/version.sh)
- "echo $latestTag"
artifacts:
files:
- '**/*'
discard-paths: yes
And results in console:
CodeBuild
I also have to mark that when i paste only for example echo 222 into version.sh file i got right answer in CodeBuild console.
