In a web project, jetty is used. When building the project with gradle, I found the prompt Plugin with id’jetty’ not found. That is, the plug-in could not be found.

The Groovy code is as follows:

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'
}

The prompt is as follows

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:
Run with –stacktrace option to get the stack trace. Run with –info or –debug option
to get more log output. Run with –scan to get full insights.

* Get more help at https://help.gradle.org

I went to the official website and found a post https://discuss.gradle.org/t/gradle2-still-cant-specify-jetty-version/5069

It is said that jetty cannot specify a specific version in Gradle 1.x, but my hint is that this plug-in is not found at all, I am very confused. . . .

Someone in the post said that I recommend a third-party library gretty. I tried it and it succeeded.

If you are using Gradle version 2.1 or higher, just these few lines of code will do.

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

Otherwise, write a few more lines:

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"

This is my 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'
}

The results of the operation are as follows:
