SonarScanner is configured in Jenkins Tools, but '${scannerHome}' is not recognized as an internal or external command

Question

i'm tring to use SonarQube inside my Jenkinsfile

pipeline{
    agent any 
    stages{
        stage('build'){
            steps{
                // invoke command to build with maven
                bat 'mvn clean install'
            }
        }

        stage('SonarQube') {
            environment {
                scannerHome = tool 'SonarQubeScanner'
            }
            steps {
                withSonarQubeEnv('SonarQube') { 
                    bat '${scannerHome}/bin/sonar-scanner.bat'
                }
            }
         }
    }
}

this is my SonarQube server

and this is SonarScanner

what is wrong with withSonarQubeEnv step:

withSonarQubeEnv('SonarQube') { 
    bat '${scannerHome}/bin/sonar-scanner.bat'
}

that I always got an error

'${scannerHome}' is not recognized as an internal or external command,

Answer 1

I see two problems:

1. you didn't add any installer to SonarQubeScanner tool (only checkbox is checked)
2. the code is incorrect

---

Single quotes are not evaluated (treat as is). It means that:

def value = 'ABC'
println '${value}/bin/sonar-scanner.bat'

prints ${value}/bin/sonar-scanner.bat. You have to use double quotes:

def value = 'ABC'
println "${value}/bin/sonar-scanner.bat"

prints ABC/bin/sonar-scanner.bat.

The code should be equal to:

withSonarQubeEnv('SonarQube') { 
    bat "${scannerHome}/bin/sonar-scanner.bat"
}
