From 582ccd02c07eed09e45e5a49c59c04d033b10e98 Mon Sep 17 00:00:00 2001 From: Ting-Yuan Huang Date: Thu, 19 Oct 2023 13:29:41 -0700 Subject: [PATCH] Add generated files to target source sets instead of creating source sets and making default source sets depend on them. This avoids breaking kotlin.mpp.applyDefaultHierarchyTemplate. Common source sets are untouched, because otherwise the generated sources for them would be observed by downstream compilations and be inconsistent with current KMP build scheme. Alternatively, we could add all generated files, common or target, directly to compilation tasks and keep default source sets untouched. The drawback is that generated files won't be seen by IDE. We would have to build IDE plugins and implement our own model builder to register generated files to IDE. TODO: Add common source sets to their corresponding compilation for the new KMP build scheme. --- .../google/devtools/ksp/gradle/KspAATask.kt | 23 +++-- .../devtools/ksp/gradle/KspSubplugin.kt | 98 ++++++------------- .../com/google/devtools/ksp/test/HmppIT.kt | 2 + 3 files changed, 48 insertions(+), 75 deletions(-) diff --git a/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspAATask.kt b/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspAATask.kt index c47e8ec44a..8525b3bfd7 100644 --- a/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspAATask.kt +++ b/gradle-plugin/src/main/kotlin/com/google/devtools/ksp/gradle/KspAATask.kt @@ -30,7 +30,6 @@ import org.gradle.workers.WorkParameters import org.gradle.workers.WorkerExecutor import org.jetbrains.kotlin.gradle.dsl.KotlinJvmCompilerOptions import org.jetbrains.kotlin.gradle.plugin.KotlinCompilation -import org.jetbrains.kotlin.gradle.plugin.KotlinSourceSet import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinCommonCompilation import org.jetbrains.kotlin.gradle.tasks.AbstractKotlinCompileTool import java.io.ByteArrayOutputStream @@ -71,7 +70,6 @@ abstract class KspAATask @Inject constructor( kotlinCompilation: KotlinCompilation<*>, kotlinCompileProvider: TaskProvider>, processorClasspath: Configuration, -
