NPE in `RedactedIrGenerationExtension` during `compileTestFixturesKotlin`

[aSemy]

• Kotlin 1.7.0
• Spring Boot 2.7.1
• redacted 1.1.0
• Gradle 7.4.2

I'm trying to migrate from Sekret because of 1.7.0 support.

I did a find and replace to update the annotation, removed the Sekret plugin, and applied the redacted plugin to all subprojects (I have a multi-module Gradle project) via a buildSrc convention plugin.

However I get an NPE

e: java.lang.NullPointerException
	at dev.zacsweers.redacted.compiler.RedactedIrGenerationExtension.generate(RedactedIrGenerationExtension.kt:31)

I can run gradle assemble successfully.

However when I run gradle testClasses --no-build-cache I get an exception.

There are no @Redacted annotations anywhere, except for in src/main directories - so I'm not sure what the problem is. The only guess I have is that it's something to do with the java-test-fixtures plugin?

buildSrc plugins

Kotlin JVM convention

// buildSrc/.../kotlin-jvm.gradle.kts

package buildsrc.convention

plugins {
    kotlin("jvm")
    `java-library`
    jacoco

    id("dev.zacsweers.redacted")
}

extensions.configure<dev.zacsweers.redacted.gradle.RedactedPluginExtension> {
    redactedAnnotation.set("net.afanasev.sekret.Secret") // this does not affect the NPE
}

Spring Boot convention

Some subprojects are Spring Boot libraries. I'm only using kapt for the Spring Boot configuration processor. I tried disabling it though - but no change.

// buildSrc/.../spring-boot.gradle.kts

plugins {
    id("org.springframework.boot")
    id("buildsrc.convention.kotlin-jvm")
    kotlin("plugin.spring")
    kotlin("plugin.jpa")
    // kotlin("kapt") // required by: spring-boot-configuration-processor
}

dependencies {
    // kapt(platform(SpringBootPlugin.BOM_COORDINATES))
    // annotationProcessor(platform(SpringBootPlugin.BOM_COORDINATES))
    //
    // kapt("org.springframework.boot:spring-boot-configuration-processor") {
    //     because("required by spring-boot-configuration-processor")
    // }
    // annotationProcessor("org.springframework.boot:spring-boot-configuration-processor") {
    //     because("required by spring-boot-configuration-processor")
    // }
}

Subproject config

And then in some subprojects, I have the test-fixtures plugin applied

plugins {
    buildsrc.convention.`spring-boot`
    `java-test-fixtures`
}

dependencies {
    implementation(projects.service.core)

    implementation(libs.springBoot.starterWeb)

    testImplementation(testFixtures(projects.service.testLib))

    testImplementation(libs.springBoot.starterTest)
    testImplementation(libs.kotlinx.coroutinesTest)

    testFixturesImplementation(projects.service.core)
    testFixturesImplementation(libs.kotest.property)
}

Can you make a minimally reproducing sample project? I have some familiarity with test fixtures but not enough to say if they wouldn't have access to classes in src/main
