Spotless uses afterEvaluate

[asaikali]

Spotless plugin is generating a deprecation warning with Gradle 6.0.1

Using method Project#afterEvaluate(Action) when the project is already evaluated has been deprecated. This will fail with an error in Gradle 7.0. The configuration given is ignored because the project has already been evaluated. To apply this configuration, remove afterEvaluate.

I am configuring spotless from a within the buildSrc folder for all projects that apply the java plugin

java-library-conventions.gradle.kts contains

    id("com.gorylenko.gradle-git-properties")

spotless {

The buildSrc/build.gradle.kts contains

I'm using Gradle 6.0.1 myself, but I haven't seen this warning so far. At some point, you must say something like apply from: 'java-library-conventions.gradle.kts'. My guess is that you're doing something like this:

afterEvaluate {
  if (hasPlugin(Java)) {
    apply from: 'java-library-conventions.gradle.kts'
  }
}

The afterEvaluate in Spotless would be hard to avoid. It would be nice if Gradle allowed some kind of trampolining so that afterEvaluates could compose with each other, but it looks like that's not their plan for now...

I tried to create a simple single project with spotless with no child modules but I did not see the deprecation warning. My project is multi module project below is an example of one of the modules is configured.

plugins {
    `java-library-conventions`
    `java-test-fixtures-conventions`
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.flywaydb:flyway-core")
    runtimeOnly("org.postgresql:postgresql")
} 

Rather than using the root project to configure the child projects I created my own plugin in the buildSrc similar to what junit does

The root project is tiny it only looks like this.

subprojects {
    repositories {
        mavenCentral()
    }
    group = "com.example"
    version = "1.0.0" 
}

I hope this helps.

I think that confirms that my comment above is a correct diagnosis. This line in the junit buildSrc would cause this.

https://github.com/junit-team/junit5/blob/8dfcee3207d982db1a7bb2a11b44cd4f4a7a1116/buildSrc/src/main/kotlin/java-library-conventions.gradle.kts#L271-L272

This might be why junit has kept spotless outside of this plugin:

https://github.com/junit-team/junit5/blob/abb6fdcb12a71a395aefff8d76a4ee756bfaa7d4/build.gradle.kts#L121-L141

You can definitely configure spotless inside your plugin if you want. You just can't do it inside an afterEvaluate block. FWIW, I think this is a feature-deficiency in Gradle - it seems like it should be possible to trampoline afterEvaluate calls so that this would not be a problem (though I might be wrong). So I think your paths forward are either

1. don't configure Spotless inside an afterEvaluate block
2. see if you can get Gradle to enhance afterEvaluate

Also, we just launched blowdryer, which has been really helpful to us internally for structuring our build scripts. If you have multiple git repositories, I think it's a lot better than the buildSrc plugin route. We haven't started marketing it yet, but we just shipped 1.0

I don't have AfterEvaluate in my plugin below is the complete java-library-conventions.gradle.kts

But how do you apply this plugin? Search java-library-conventions.gradle.kts throughout all your .gradle files, and trace where it gets called. I suspect one of them is called within an afterEvaluate. Another possibility might be if you're applying this script from a different project. e.g. if :foo is applying Spotless to :bar after :bar has already finished its configuration. If it's this latter case, you should be able to fix with evaluationDependsOn.

Found anything interesting?

I'm closing due to inactivity, but not due to lack of curiosity! If you ever find anything interesting about what was happening here, I hope you'll come back and tell us what you find.

From the stacktrace we can see that SpotlessPlugin creates SpotlessExtension which in its constructor reaches out to the root project to apply the same SpotlessPlugin to it and does afterEvaluate {}. That's this afterEvaluate {} which emit the deprecation message.

https://github.com/diffplug/spotless/blob/gradle/3.27.1/plugin-gradle/src/main/java/com/diffplug/gradle/spotless/SpotlessExtension.java#L66

In other words, on multi project builds and when applied to a subproject, the Spotless plugin tries to go up the project hierarchy to the root project, adding an afterEvaluate block to an already evaluated project. This doesn't work and the registered afterEvaluate hook is ignored as said in the warning. This should be fixed and will become an error in Gradle 7 anyway.
