Converting from Gradle 3.1 to 6.1.1, a copy-paste of the com.moowork.gulp plugin DSL format is failing for me. Isn’t the 6.1.1 format the following plugins:

```
plugins {
     id "com.moowork.gulp" version "1.3.0"
}

task example {
      println 'Configuration stage'

     doLast {
         println 'Execution stage'
     }
}

```

The simple build.gradle file yields the following:

```
$ ./gradlew example

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'example'.
> Could not resolve all artifacts for configuration ':classpath'.
> Could not find com.moowork.gradle:gradle-node-plugin:1.3.0.
 Searched in the following locations:
   - https://plugins.gradle.org/m2/com/moowork/gradle/gradle-node-plugin/1.3.0/gradle-node-plugin-1.3.0.pom
 If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.
 Required by:
     project : > com.moowork.gulp:com.moowork.gulp.gradle.plugin:1.3.0

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.

What am I missing?

Hey @Joseph_Fota,

It looks like the POM of `gradle-node-plugin:1.3.0` is broken. It was probably working before because before 6, Gradle was also trying to resolve JARs without POMs by default. That’s what this info is about:

> If the artifact you are trying to retrieve can be found in the repository but without metadata in ‘Maven POM’ format, …

It looks like this was fixed in `gradle-node-plugin-1.3.1`. Easiest fix would probably to add that plugin as well - `id "com.moowork.gulp" version "1.3.1"` - to force an upgrade.

Maybe you can also report this to com.moowork.gulp plugin maintainers.

No joy with the upgrade from 1.3.0 to 1.3.1

```
$ ./gradlew example

FAILURE: Build failed with an exception.

* Where:

Build file '/home/mapr/workarea/example/build.gradle' line: 2

* What went wrong:

Plugin [id: 'com.moowork.gulp', version: '1.3.1'] 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 'com.moowork.gulp:com.moowork.gulp.gradle.plugin:1.3.1')

Searched in the following repositories:

Gradle Central Plugin Repository

```

For fun, I substituted the plugin with another plugin.

```
plugins {
    id "nebula.os-package" version "2.2.6"
}

```

That failed too. Do the plugins no longer work for 6.1.1?

What I meant to say is that the `gulp` plugin transitively applies the `node` plugin. The latter should be upgraded to version `1.3.1`. This works:

```gradle
plugins {
    id "com.moowork.gulp" version "1.3.0"
    id "com.moowork.node" version "1.3.1"
}

task example {
    println 'Configuration stage'

    doLast {
        println 'Execution stage'
    }
}

```
