## Example

```gradle
//Snippet
settingsEvaluated { settings ->
    settings.pluginManagement {
        repositories {
            maven {
                credentials {
                    username "username"
                    password "password"
                }
                url "https://nexus.example.com"
                
            }
        }
    }
}
initscript {
    repositories {
        maven {
            credentials {
                username "username"
                password "password"
            }
            url "https://nexus.example.com"
            
        }
    }
    dependencies {
        classpath "com.netflix.nebula:gradle-ospackage-plugin:5.1.0"
        classpath "com.github.jengelman.gradle.plugins:shadow:4.0.4"
        classpath "gradle.plugin.com.selesse:gradle-git-changelog:0.3.0"
    }
}
allprojects {
    apply plugin: 'com.netflix.gradle.plugins.rpm.RpmPlugin'
    apply plugin: 'com.github.jengelman.gradle.plugins.shadow.ShadowPlugin'
    apply plugin: 'com.selesse.gradle.git.changelog.GitLogPlugin'
}
//...

```

Am I doing something wrong here.  
Stacktrace is not very helpfull either.

You are using the implementation class of the plugins (ex: `com.netflix.gradle.plugins.rpm.RpmPlugin`) as the ID. The ID of that particular plugin is `nebula.rpm`.

However, you do need to use the implementation class, not the ID, in an init script. In order to do that, you should remove the quotes around the implementation classes:

```groovy
allprojects {
    apply plugin: com.netflix.gradle.plugins.rpm.RpmPlugin
    apply plugin: com.github.jengelman.gradle.plugins.shadow.ShadowPlugin
    apply plugin: com.selesse.gradle.git.changelog.GitLogPlugin
}

```

Including

> allprojects {

in init.gradle produces this error

> Could not get unknown property ‘com’ for root project ‘sftp-client’ of type org.gradle.api.Project.

If you try to reference a class in an init script without adding it to the classpath, that error will occur in any version of Gradle. The line you copied from the thread isn’t stand-alone. It’s within the context of the larger file posted by the original poster.

I too am getting the error “…unknown property ‘com’”

I have a project that creates a custom wrapper which includes a script in init.d named artifactory.gradle

```gradle
initscript{
	Properties properties = new Properties()
	properties.load(new File(getGradleUserHomeDir(), 'gradle.properties').newDataInputStream())

	repositories {
		maven {
			url properties.artifactory_contextUrl + '/gradle-plugins-virtual'
			credentials {
				username = properties.artifactory_user
				password = properties.artifactory_password
			}
		}
	}
	dependencies {
		classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.17.2"
	}
}

apply plugin: com.jfrog.artifactory //unknown property com
// apply plugin: 'com.jfrog.artifactory' //gives plugin not found error

println "artifactory.gradle - called"

```

when I run a project configured to use this wrapper I get the errors indicated here.

Any help appreciated. How do I verify my classpath?

`com.jfrog.artifactory` does not look like a class name!
