How to get rid of "generateEffectiveLombokConfig... without declaring an explicit or implicit dependency" error

[sc-moonlight]

First, thanks for the plugin. I'm seeing the same gradle warning as others have. I've tried addressing by adding dependencies and updating to 6.4.0, but I still can't get it to go away. I'm hoping you can point me to what I'm doing wrong.

> Task :core:generateEffectiveLombokConfig
Execution optimizations have been disabled for task ':core:generateEffectiveLombokConfig' to ensure correctness due to the following reasons:
  - Gradle detected a problem with the following location: .../core/build/generated-src/java'. Reason: Task ':core:generateEffectiveLombokConfig' uses this output of task ':core:generateMyClasses' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed. Please refer to https://docs.gradle.org/7.3.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.

Important parts from my build.gradle (slightly redacted)

plugins {
id "io.freefair.lombok" version "6.4.0"
}

task generateMyClasses(type: JavaExec) {
    doFirst{
        File generatedSrcDir = file("$buildDir/generated-src/java")
        if (!generatedSrcDir.exists()) {
            generatedSrcDir.mkdirs()
        }
    }

    inputs.files(["$projectDir/src/main/resources"])
    outputs.dir("$buildDir/generated-src/java")
    classpath = configurations.generatemyclasses
    mainClass = '......Generator'
    args = [
            'all', 'src/main/resources/',"$buildDir/generated-src/java"
    ]
    dependencies {
    }
}
processResources.dependsOn 'generateMyClasses'

sourceSets {
    main {
        java {
            srcDirs 'src'
            srcDirs "${buildDir}/generated-src/java"
        }
    }
}

compileJava {
    dependsOn 'generateMyClasses'
}

tasks.withType(io.freefair.gradle.plugins.lombok.tasks.Delombok.class) {
        dependsOn(generateMyClasses)
}

Gradle does not know that parts of sourceSets.main.java are created by your generateMyClasses task. Therefore all tasks using sourceSets.main.java as input (like compileJava or generateEffectiveLombokConfig) do not get an implicit dependency on your task.

You could try something like this:

sourceSets.main.java.srcDirs generateMyClasses

or

sourceSets.main.java.srcDirs files("${buildDir}/generated-src/java").builtBy(generateMyClasses)

Awesome! There are 10,000 ways to write this stuff in Gradle, so it's hard to know how to do it "correctly". I thought I was close,

Based on your suggestion, this change seems to work!

-            srcDirs "${buildDir}/generated-src/java"
+            srcDirs files("${buildDir}/generated-src/java").builtBy(generateMyClasses)

I appreciate the help
