Here is the Groovy example:
static def getScript(fileName, execution) {
def processDefinitionId = execution.getProcessDefinitionId()
def deploymentId = execution.getProcessEngineServices().getRepositoryService().getProcessDefinition(processDefinitionId).getDeploymentId()
def resource = execution.getProcessEngineServices().getRepositoryService().getResourceAsStream(deploymentId, fileName)
def scannerResource = new Scanner(resource, 'UTF-8')
def resourceAsString = scannerResource.useDelimiter('\\Z').next()
scannerResource.close()
GroovyShell shell = new GroovyShell()
return shell.parse(resourceAsString)
}
def helper = getScript("helpers/helper_classes.groovy", execution)
To include general code needs a lot of boilerplate!
I think this should be improved. Something like this would be great:
GroovyShell shell = new GroovyShell()
def helper = shell.parse("deployment://helpers/helper_classes.groovy")
