Hi @msheiny,

Your code didn't work for me, so I did some improvements now it's working. (Jun/2019).
Anyway, thank you so much. Your code was the inspiration. ;-)

import org.apache.commons.io.FileUtils
import org.apache.commons.fileupload.FileItem
import com.google.jenkins.plugins.credentials.oauth.JsonServiceAccountConfig
import com.google.jenkins.plugins.credentials.oauth.GoogleRobotPrivateKeyCredentials

def jenkinsInstance = Jenkins.getInstance()

// Google Credential
def googleCredentialId = "my-credential-id"
def googleCredentialFile = new File("/path/to/my/json/file.json")
def googleCredentialFileInputStream = new FileInputStream(googleCredentialFile)
def googleCredentialFileItem = [ getName: { return googleCredentialFile.getName() }, getSize: { return 1L }, getInputStream: { return googleCredentialFileInputStream }, get: { return FileUtils.readFileToByteArray(googleCredentialFile) } ] as FileItem
def googleJsonServiceAccountConfig = new JsonServiceAccountConfig(googleCredentialFileItem, null)
def googleCredential = new GoogleRobotPrivateKeyCredentials(googleCredentialId, googleJsonServiceAccountConfig, null)

// Saving
def domain = Domain.global()
def store = jenkinsInstance.getExtensionList('com.cloudbees.plugins.credentials.SystemCredentialsProvider')[0].getStore()
store.addCredentials(domain, googleCredential)
