Could not find property 'Fork' on root project XXX

[meltzow]

after installed like describe I got an error (see headline) gradleWrapperVersion=2.3

any ideas why?

[tsouza]

Also getting this with JavaFork, any clue?

UPDATE: you need to import it

[kungfoo]

I have the same problem, yet I can't fix it by importing the class. This is using gradle 2.7.

I tried using both approaches that are published here: https://plugins.gradle.org/plugin/com.github.johnrengelman.processes

Always returns the following:

Could not find property 'JavaFork' on project

As @tsouza pointed out, you need to import the Fork/JavaFork task in your build file:

import com.github.jengelman.gradle.plugins.processes.tasks.*

Similar to @kungfoo, I'm importing it as well, using the import string provided by @ChristophSchall and still getting the same error. (Using Gradle 2.11)

import org.gradle.internal.os.OperatingSystem;
import com.github.jengelman.gradle.plugins.processes.tasks.*
...
project.plugins.each {
    println it
}

task runJavaServer(type: JavaFork) {
    main = 'com.something.JavaServer'
    classpath = sourceSets.main.runtimeClasspath
    jvmArgs "-Xmx1g"
    args "--someArgs"
}

But still getting this output (the plugins are printed out to show that it is being imported):

gradle runJavaServer

@johnrengelman Any thoughts?

also seeing this on gradle 2.11 with Fork works fine on 2.10

[ddelponte]

I'm seeing this with gradle 5.5
