gradle sync error file not found - eclipse

Question

I've a simple task which creates a bat file with task name which start with "server" and when executing the bat file gradle jobs starts, Code below :
task runWebServers {
def fileName = "runwebserver.bat"
def inputFile = new File("./"+fileName)
if(inputFile.exists()){
inputFile.delete()
}
project.tasks.collect { task ->
if(task.name.startsWith('server')) {
inputFile.append("start gradle "+task.name+"\r\n")
}
}
}
This task used to work a while back but now I started getting this error Sync Failed: File not found
StackTrace Below:
Synchronize Gradle projects with workspace failed due to an error in the referenced Gradle build.

I tried delete the .gradle folder in the project work space and re-creating it but it didn't work. restarted machine and eclipse didn't help either.
Update: I'm using gradle 4.5 and This seems to be an Buildship related issue as doing a gradle clean build from cmd works fine. though when using eclipse buildship to a gradle refresh this error comes. eclipse is using local installation of gradle. buildship version:2.2.1

Answer 1

As it stands, that code will be executed at configuration time, not only when the task is executed. You need to move it into a doLast block like so:
task runWebServers {
doLast {
def fileName = "runwebserver.bat"
def inputFile = new File("./"+fileName)
if(inputFile.exists()){
inputFile.delete()
}
project.tasks.collect { task ->
if(task.name.startsWith('server')) {
inputFile.append("start gradle "+task.name+"\r\n")
}
}
}
}
