org.grails.grails-web & org.grails.grails-gsp Gradle Plugin ids with versions not working for snapshots

[jamesfredley]

org.grails.grails-web & org.grails.grails-gsp Gradle Plugin ids work with 6.2.1, but not with 6.2.2-SNAPSHOT. We must be missing something when we publish the grails-gradle-plugin snapshots to repo.grails.org.

The workaround is to use:

apply plugin: 'org.grails.grails-web'
apply plugin: 'org.grails.grails-gsp'

which does allow the project to load and gradle downloads the following files. Only the jar file has a definition for these ids. Removing the version does to resolve the issue.

6.2.1 works fine

buildscript {
    repositories {
        maven { url "https://repo.grails.org/grails/core" }
        mavenCentral()
    }
    dependencies { // Not Published to Gradle Plugin Portal
        classpath "org.grails:grails-gradle-plugin:6.2.1"
    }
}
plugins {
    id "groovy"
    id "org.grails.grails-web" version "6.2.1"
    id "org.grails.grails-gsp" version "6.2.1"
    id "com.github.erdi.webdriver-binaries" version "3.2"
    id "war"
    id "idea"
    id "com.bertramlabs.asset-pipeline" version "4.3.0"
    id "application"
    id "eclipse"
}

6.2.2-SNAPSHOT fails

These gradle plugins will load by version number if placed in settings.gradle, which downloads the pom file from the directories above, and can then be references by id in build.gradle, since they have already been loaded by settings.gradle. The version number cannot be repeated in build.gradle.

settings.gradle

pluginManagement {
    repositories {
        maven { url "https://repo.grails.org/grails/core/" }
    }
    plugins {
        id "org.grails.grails-web" version "6.2.2-SNAPSHOT"
        id "org.grails.grails-gsp" version "6.2.2-SNAPSHOT"
    }
}

build.gradle

plugins {
        id "groovy"
        id "org.grails.grails-gsp"
        id "org.grails.grails-web"
        id "war"
        id "idea"
        id "com.bertramlabs.asset-pipeline" version "5.0.1"
        id "application"
        id "eclipse"
}

This works as designed. It uses the version of grails-gradle-plugin that is in the class path because they are resolved from within that jar. You would never have a different version of the plugins.

This will be fixed when we break up and publish the plugins independently.

See #340

But why does a release version work with id and version and a snapshot fails with id or id and version? See full example in first comment.

works with classpath "org.grails:grails-gradle-plugin:6.2.1"

    id "org.grails.grails-web" version "6.2.1"
    id "org.grails.grails-gsp" version "6.2.1"

fails with classpath "org.grails:grails-gradle-plugin:6.2.2-SNAPSHOT"

    id "org.grails.grails-web" version "6.2.2-SNAPSHOT"
    id "org.grails.grails-gsp" version "6.2.2-SNAPSHOT"

fails with classpath "org.grails:grails-gradle-plugin:6.2.2-SNAPSHOT"

    id "org.grails.grails-web"
    id "org.grails.grails-gsp"

[codeconsole]

perhaps because gradle plugins don't support snapshots?

why are you setting the version in settings.gradle?

[jamesfredley]

The main example at the top does not use settings.gradle or buildSrc. There is an example lower down with settings.gradle, to show the different behavior.
