Enforcer implementation must change due to Gradle 7

[aalmiray]

Current enforcer (0.8.0) will output a warning when rules related to artifact resolution are configured in a build. This warning occurs because settings resolves configurations belonging to a project, and that's a big no-no in Gradle 7.

The fix is to resolve configurations with a task that's registered on the project. This would make dependency resolution aware rules be good citizens however that also means rules won't be executed automatically after all projects are configured but not yet executed. And here lies the problem if the current design stays put:

• some rules should be run as early as possible (such as RequireGradleVersion).
• some rules have to run as late as possible (dependency resolution aware).
• some rules may run at the end of the build.

To complicate matters, registering a buildFinished() listener is also a no go in Gradle 7 due to configuration cache (currently incubating since 6.6.). It may be the case that some rules will have to be removed or their effectiveness may become limited. It's unclear as of now if a combination of automatic execution as it's right now (early rules) and enforce tasks (dependency resolution aware) would be a good fit. Or perhaps all rules should be executed via tasks. Whatever the case it's likely that enforcer rules may not be compliant with configuration cache, in which case if that feature becomes stringent then enforcer may not be possible at some point.

Watch out for https://github.com/gradle/gradle/issues/15522

It fails with Gradle 7, plugin version 0.9.0:

> Failed to apply plugin 'org.kordamp.gradle.enforcer'.
   > class org.gradle.api.internal.project.DefaultProject_Decorated cannot be cast to class org.gradle.api.initialization.Settings (org.gradle.api.internal.project.DefaultProject_Decorated and org.gradle.api.initialization.Settings are in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader @57baeedf)

[bondolo]

If another release of the plugin occurs before you are able to fix this issue perhaps add a version check and fail to run if Gradle 7+ is being used. (As usual I flailed for a while thinking the problem was my fault before learning that it wasn't expected to work).

[aalmiray]

@bondolo I'm waiting til Gradle 7.3 comes out to have another go at migration. Why that particular release? Because Gradle has a history of unstable releases after a major release. Things usually settle after a couple of minor releases are posted.

same issue with gradle 7.3.1

[rr-nick-tan]

get the same issue on gradle 7.4.0 it's a blocker of adoption this enforcer plugin in our projects.

* What went wrong:
An exception occurred applying plugin request [id: 'org.kordamp.gradle.enforcer', version: '0.10.0']
> Failed to apply plugin 'org.kordamp.gradle.enforcer'.
   > org.gradle.api.internal.project.DefaultProject_Decorated cannot be cast to org.gradle.api.initialization.Settings

[aalmiray]

Are you applying the plugin at the right place? Note that there are 2 plugins https://kordamp.org/enforcer-gradle-plugin/#_applying_the_plugin

@aalmiray , ah, right, I use it at project level, it works after use the 'org.kordamp.gradle.project-enforcer'. thx

[bmuschko]

Is this still an issue? I tried with Gradle 8.1.1 and enforcer plugin 0.13.0 and didn't see build failure or warning message.

[aalmiray]

@bmuschko That's strange. That would mean a warning that used to appear in Gradle 7 was removed while the deprecated behavior was kept in place. I think that's highly unlikely but also I have not read through the releases notes for 8 to check if the old behavior was deemed acceptable in the end.

[bmuschko]

@aalmiray My build script:

plugins {
    id 'org.kordamp.gradle.project-enforcer' version '0.13.0'
    id 'java'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'commons-lang:commons-lang:2.4'
}

enforce {
    rule(enforcer.rules.BannedDependencies) { r ->
        // search only on compile and runtime classpaths
        r.configurations.addAll(['compileClasspath', 'runtimeClasspath'])
        // ignore all classes under the following package
        r.exclude('org.apache.maven')
        r.exclude('org.apache.maven:badArtifact')
        r.exclude('*:badArtifact')
        // only 1.0 of badArtifact is allowed
        r.include('org.apache.maven:badArtifact:1.0')
    }
}

Does this only happen with the --configuration-cache flag added?

[aalmiray]

Ah I see. project-enforcer should work fine as configurations will be resolved from the owning scope (the project) as the plugin is applied to the project. The problem arises when using the enforcer plugin which should be applied to Settings. In the latter case the invoking scope (Settings) differs from the owning scope (project) and the warning is raised.

[bmuschko]

Gotcha. Do you have plans to fix this issue?

[aalmiray]

I have not come up with a plan that would let the build enforcer to continue to work as it does today. Only a few of my builds use Gradle 7 and none use 8 thus I’m not in a rush to fix it. That might change by the end of 2023.

[binkley]

I'm not sure is my problem is related to this issue, or if I should file a separate issue. I'm using Gradle 8.x with version catalogs. I've setup the plugin cleanly to specify gradle/libs.versions.toml to 0.13.0, and build.gradle to pull in the plugin with a plugin "alias". Though the setup is different, Maven use of plugin works great as expected.

However, when I add an "enforce" block to build.gradle I syntax troubles. This fails spectacularly when uncommented:

// Do read the documentation on Enforcer to pick what makes sense to you:
// https://kordamp.org/enforcer-gradle-plugin/#_rule_dsl
/*
enforce {
     configure()
     rule()
}
*/

I feel I'm doing something wrong, however I'm following the documentation, and have tried several variations.

[binkley]

@aalmiray: Following up to see what status is on this issue.

@jwlibby and I work on a book for examples in the JVM world with Gradle and Maven on good practices in the build pipeline (local development, CI [ie, GitHub actions]). We have Enforcer for Maven working, and would like to show examples and documentation on using Enforcer in Gradle. (https://github.com/binkley/modern-java-practices -- example project; the writing is in the wiki pages.)

[aalmiray]

Status quo remains. This plugin works with Gradle 8.x despite the warnings issued when build-enforcer is applied to settings.gradle.

AFAICT the enforcer plugin when applied to a project (build.gradle) should work without warnings.

This being said, the use of build-enforcer may no longer be possible once Gradle 9 comes out, leaving only the use of enforcer.

[binkley]

@aalmiray Thank you for such good information! I'll unblock our story card on Enforcer for Gradle, and see how far we get, and keep an eye on what happens when Gradle 9 soon comes.

[binkley]

@aalmiray I have this working now, thank you! My goal:

• Passing build when checking for the same version of Gradle in Enforcer and that used by gradlew.
• Failing build at start when Enforcer checks for a different Gradle version than gradlew.

Two observations:

1. Docs not helpful for new people to get started. I found the integration tests for the plugin to see how to set things up. I found that:
   • I needed to put Enforcer into settings.gradle rather than build.gradle (which makes sense when I think it through)
   • I do not believe I have access to Gradle's version catalogs when in "settings" (I may be wrong), so fell back on older methods
   • A simple example project for folks to study would be helpful here
2. Enforcer uses an older version of commons-lang3, and since I'm playing with classpath in settings.gradle, this impacts project dependencies. The older version broke DependencyCheck. I worked around this with an explicit "commons-lang3" version in classpath before referencing the Enforcer plugin.

Here is the settings.gradle I used:

buildscript {
    repositories {
        gradlePluginPortal()
        mavenCentral()
    }

    dependencies {
        classpath "org.apache.commons:commons-lang3:3.15.0"
        classpath "org.kordamp.gradle:enforcer-gradle-plugin:$enforcerPluginVersion"
    }
}

apply plugin: "org.kordamp.gradle.enforcer"

enforce {
    rule(enforcer.rules.RequireGradleVersion) { r ->
        r.version = "$gradleWrapperVersion" // Pulled in from "gradle.properties"
    }
}

[aalmiray]

Applying the plugin in settings.gradle requires using the build-enforcer plugin which will likely break with Gradle 9. However, this plugin gives you the Maven equivalent of being active all the time (when maven-enforcer-plugin is bound to the validate phase for example).

Applying the plugin in build.gradle requires using the enforcer plugin which should work with Gradle 9.

I don't have concrete experience with versions catalog but I venture I guess they are not available during evaluation of the settings.gradle script. Versions catalog are still hacky IMHO.

I suppose I could upgrade dependencies and release a newer version.

[binkley]

@aalmiray Cool. I'll see if I can do the same with build.gradle. I don't know what the restrictions are between "settings" and "build" that needs a diff plugin. My test cases were trivial, and worked, so there must be Rules or other things impacted between those two files.

When I get it working, I'll post my sample build.gradle changes here.

[aalmiray]

Plugins applied in settings.gradle target the Settings model while plugins applied to build.gradle target the Project model.

[binkley]

I like that explanation. It makes sense. Perhaps docs for Rules might suggest when they are better applied to Settings or to Project. For example, check Gradle or JVM versions makes more sense to me in Settings, but check for banned dependencies makes more sense in Project.

[aalmiray]

In its current state, yes I'd agree a distinction may be needed. But given that the build-enforcer plugin will be removed once Gradle 9.x stabilizes itself there's not much incentive to change the docs at the moment.

[binkley]

I'd be happy to contribute example snippets once the plugin project is ready. I want more projects able to adopt this with minimal friction.

[aalmiray]

Thank you. I'll post a release in the coming days.
