Gradle dependency management plugin - gradle

Question

I am trying to run the following minimal gradle build file including the dependency management plugin:
buildscript {
repositories {
mavenCentral()
maven {
url "https://plugins.gradle.org/m2/"
}
}
}
plugins {
id "java"
id "io.spring.dependency-management" version "1.0.4.RELEASE"
}
But then running gradle fails:
* What went wrong:
Plugin [id: 'io.spring.dependency-management', version: '1.0.4.RELEASE'] 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 'io.spring.dependency-management:io.spring.dependency-management.gradle.plugin:1.0.4.RELEASE')
Searched in the following repositories:
Gradle Central Plugin Repository
* 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
Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0.
See https://docs.gradle.org/4.5.1/userguide/command_line_interface.html#sec:command_line_warnings
Is there a missing dependency in the gradle file?

Answer 1

The plugin cannot be found because you defined repositories inside your build script and tried to use plugin outside it. Remove buildscript or add repositories for your build file also.
(Dependencies and repositories defined inside build script are accessible in that buildscript scope)
Example:
plugins {
id "java"
id "io.spring.dependency-management" version "1.0.4.RELEASE"
}
repositories {
mavenCentral()
maven {
url "https://plugins.gradle.org/m2/"
}
}
