Adding a file in bootstrap.groovy in grails 3? - grails

Question

I would like to add a file in the bootstrap.groovy file in grails 3.3.9 version.
In the bootstrap.groovy:
package com.nuevaconsulting
import com.nuevaconsulting.embrow.*
class BootStrap {
def init = { servletContext ->
def filePath = "C:/Grails/embrow/grails-app/conf/resourcesresources/1.csv"
new File(filePath).splitEachLine(',')
{
fields ->
def employee = new Employee(
mirId: fields[0].trim(),
cancer : fields[1].trim(),
profile : fields[1].trim(),
pubmed : fields[1].trim()
)
if ( employee.hasErrors() || employee.save(flush: true) == null) {
log.error("Could not import employee ${ employee.errors}")
}
log.debug("Importing employee ${ employee.toString()}")
}
def destroy = {}}}
When I execute run-app, I ended-up with the following error
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':bootRun'.
