gradle 提示 : Plugin with id 'jetty' not found.

在一个web项目中，用到了jetty，在用gradle构建项目时发现提示 Plugin with id 'jetty' not found.即找不到这个插件。

Groovy代码如下：

apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'jetty'

repositories {
	mavenCentral()
}

dependencies {
	providedCompile 'javax.servlet:servlet-api:2.5',
					'javax.servlet.jsp:jsp-api:2.1'
	runtime 'javax.servlet:jstl:1.1.2',
			'taglibs:standard:1.1.2'
}

提示如下

FAILURE: Build failed with an exception.

* Where:
Build file 'H:\gradleCode\test\build.gradle' line: 3

* What went wrong:
A problem occurred evaluating root project 'test'.
> Plugin with id 'jetty' not found.

* Try:

去官网看了下，发现了个帖子https://discuss.gradle.org/t/gradle2-still-cant-specify-jetty-version/5069

说的是在Gradle 1.x 中jetty不能指定特定的版本，可我这的提示是根本找不到这个插件，我就很迷。。。。

帖子有人说推荐第三方库gretty 我尝试了一下，成功了

如果你用的Gradle是2.1版本以上的，就这几行代码就可以了

plugins {
  id "org.akhikhl.gretty" version "2.0.0"
}

否则就要写多几行：

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "gradle.plugin.org.akhikhl.gretty:gretty:2.0.0"
  }
}

apply plugin: "org.akhikhl.gretty"

这是我的build.gradle:

apply plugin: 'java'
apply plugin: 'war'
buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "gradle.plugin.org.akhikhl.gretty:gretty:2.0.0"
  }
}

apply plugin: "org.akhikhl.gretty"
repositories {
	jcenter()
}

dependencies {
	providedCompile 'javax.servlet:servlet-api:2.5',
					'javax.servlet.jsp:jsp-api:2.1'
	runtime 'javax.servlet:jstl:1.1.2',
			'taglibs:standard:1.1.2'
}

运行结果如下：
