3.1 to 6.1.1 plugin conversion failure

Help/Discuss Plugin Portal
#1

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'.

 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.

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

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

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)

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:

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'
    }
}
