创建Intellij插件，gradle无法找到org.jetbrains.intellij

Question

我正在尝试使用gradle为intellij创建一个插件，我已经按照jetbrains教程进行了学习： https://www.jetbrains.org/intellij/sdk/docs/tutorials/build_system/prerequisites.html

，我收到以下错误消息：

Plugin [id: 'org.jetbrains.intellij', version: '0.3.9'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.jetbrains.intellij:org.jetbrains.intellij.gradle.plugin:0.3.9')
  Searched in the following repositories:
    Gradle Central Plugin Repository

看看gradle构建文件，有以下几行：

plugins {
    id 'java'
    id 'org.jetbrains.intellij' version '0.3.9'
}

如何找出我拥有的org.jetbrains.intellij版本？如何获得0.3.9？

我的intellij版本是2018.2.2社区
