spring-boot gradle plugin can't be found

Question

I have a separate gradle script that is just adding spring-boot plugin. It looks like this:

buildscript {
    repositories {
        mavenLocal()
        mavenCe         


        

Answer 1

These are the Plugins that I am using on spring boot 2.0.1

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

My complete vanilla gradle file here (Spring boot 2.0.5)

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

OR

there is an even better option, go to the spring starter (spring boot template generating tool) start.spring.io And generate a template project from there, and build step-by-step from there.

Answer 2

could it be, that you don't have a @SpringBootApplication with a main(String[] main) on your classpath ??

Answer 3

1. Add:

   buildscript {
       repositories {
           maven {
               url "https://plugins.gradle.org/m2/"
           }
       }
       dependencies {
           classpath "org.springframework.boot:spring-boot-gradle-plugin:2.0.4.RELEASE"
       }}
   

2. Change:

   apply plugin: 'spring-boot'
   

   to:

   apply plugin: "org.springframework.boot"
   

Answer 4

As of now July first 2020, this is how I was able to configure it, and it worked! Hopefully, this can help anyone facing this problem. Note: Pay attention to the versions

buildscript {
        repositories {
            mavenCentral()
        }
        dependencies {
            classpath('org.springframework.boot:spring-boot-gradle-plugin:2.2.8.RELEASE')
        }
    }
    
    plugins {
        id 'org.springframework.boot' version '2.2.8.RELEASE'
        id 'java'
    }
    
    group 'org.capfer'
    version '1.0-SNAPSHOT'
    
    sourceCompatibility = 1.8
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.12'
        compile('org.springframework.boot:spring-boot-starter-web:2.2.8.RELEASE')
    }

Answer 5

Starting from SpringBoot 1.4.0.RELEASE the plugin package has been slightly changed.

apply plugin: org.springframework.boot.gradle.plugin.SpringBootPlugin

Answer 6

This code works for me

 plugins{

  id 'org.springframework.boot' version '2.0.3.RELEASE'

 }
