spring-boot gradle plugin can't be found - gradle

Question

I have a separate gradle script that is just adding spring-boot plugin. It looks like this:
buildscript {
repositories {
mavenLocal()
mavenCentral()
maven { url 'http://repo.spring.io/libs-release' }
}
dependencies {
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.1.8.RELEASE'
}
}
apply plugin: 'spring-boot'
Then, in another project, it is referenced like this:
apply from: '../../food-orders-online-main/spring-boot.gradle'
When I run build task I'm getting the following error:
A problem occurred evaluating script.
> Failed to apply plugin [id 'spring-boot']
> Plugin with id 'spring-boot' not found.
Someone knows what I'm doing wrong?

Answer 1

Applying a plugin by plugin id is not supported in script plugins. You must use the plugin's fully qualified class name.
apply plugin: org.springframework.boot.gradle.plugin.SpringBootPlugin
See this thread for more information.
UPDATE: Updating plugin class name.

Answer 2

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 3

This code works for me
plugins{
id 'org.springframework.boot' version '2.0.3.RELEASE'
}

Answer 4

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

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

Check your syntax and where your parentheses close } I had the same issue and it turned out my repositories { didnt contain } at the end

Answer 7

Got a similar exception
Caused by: org.gradle.internal.resolve.ArtifactNotFoundException: Could not find spring-boot-gradle-plugin-3.0.0-SNAPSHOT.jar (org.springframework.boot:spring-boot-gradle-plugin:3.0.0-SNAPSHOT:20220216.230329-214)
Running the gradle build with --refresh-dependencies fixed it

Answer 8

Below code works for me:-
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 '1.0-SNAPSHOT'
repositories {
mavenCentral()
}
dependencies {
implementation group: 'org.springframework.boot', name: 'spring-boot-
starter-web', version: '2.0.5.RELEASE'
}

Answer 9

After proxy setting ( What is the proxy IP in your organization), I have added following code in build.gradle file. The problem has gone.
sourceSets {
main {
output.setResourcesDir(java.outputDir)
}
}

Answer 10

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 11

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