My question is simple I want to extract version and name from package.json, but when I extract version and name I got more URL see attached file.Why is that?
Jenkinsfile
pipeline {
agent any
environment {
CI = 'true'
//IMAGE = bat 'node -e "console.log(require(`./package.json`).name);"'
//VERSION = bat(script: 'npm run get-version')
//VERSION = bat '(npm run version --silent)'
//PACKAGE_VERSION = bat '(node -p -e "require(\'./package.json\').version")'
GIT_COMMIT_SHORT_HASH = GIT_COMMIT.take(7)
REPOSITORY = 'repo.dimiroma.com'
PORT = '8085'
LATEST = 'latest'
}
stages {
stage('Set Build Variables') {
steps {
script {
VERSION = bat(script: '''node -e "console.log(require('./package.json').version)"''', returnStdout: true).trim()
def getProjectName = { ->
return bat(
returnStdout: true,
script: 'node -e "console.log(require(\'./package.json\').name);"'
).trim()
}
//VERSION = getProjectVersion()
IMAGE = getProjectName()

You could do it like this. I assume you got npm as a tool installed for this
stage("Build and push docker non-release"){
steps {
script {
def version = sh(returnStdout: true, script: "npm version")
echo "Version is ${version}"
def versionProps = readJSON text: version
echo "Project version is ${versionProps['project-name']}"
}
}
}
