+# Example Migration
+
+In Feb/March 2025, using the version of Declarative Gradle that would be made available as EAP 3, we migrated the [`gradle client`](https://github.com/gradle/gradle-client) to using DCL build files and a custom Software Type that described the tools and features used by this particular build.
+
+This migration allowed us to further explore this process and understand typical stumbling blocks and areas that need improvement.
+
+This document outlines that experience and our findings, and provides a case study that should approximate a real-world migration.
+You can see the results by comparing [the initial state of the repo](https://github.com/gradle/gradle-client/tree/4fb821caecbc4a55c5896624b31b201f66cc9fd0) with the state [after the migration was completed](https://github.com/gradle/gradle-client/commit/0c324821e52e82a14413f0d195ad3dda8dc687df).
+
+# How to Convert an Existing Project to Declarative Gradle
+
+The first thing to keep in mind is that using Declarative Gradle is *not* an all or nothing proposition.
+Gradle has always supported mixing build script DSLs between projects in a multi-project build using Groovy and Kotlin DSLs.
+It continues to support doing the same with DCL buildscripts, which allows us to migrate project by project.
+
+# Migration Process for Gradle-Client
+
+## Initial Setup
+
+1. Ensure the latest Gradle wrapper version
+
+Features are constantly being added to the Declarative Gradle support.  
+Any project interested in experimenting with DCL files should ensure they are using at least the latest stable Gradle release.
+For the migration of the Gradle-Client project, we upgraded the wrapper to use a nightly Gradle build [gradle-8.14-20250222002553+0000](https\://services.gradle.org/distributions-snapshots/gradle-8.14-20250222002553+0000-bin.zip) in order to get support for the very latest Declarative Gradle features.
+It is likely that by the time you are reading this, there will be a later milestone or release candidate of Gradle 8.14 available that would be usable for your own migrations.
+
+3. Identify the project to be migrated first
+
+We decided to start with the [`gradle-client` subproject](https://github.com/gradle/gradle-client/tree/main/gradle-client), as this was the most important and fully featured project contained in the Gradle Client build, which would be the most interesting to investigate.
+For your own migrations, you should probably consider which projects would be _simplest_ to migrate.
+Projects that are simpler and most similar to our declarative samples are good candidates.
+If your project _doesn't_ already use Gradle's Kotlin DSL, you'll want to migrate to this first from your Groovy build using the existing [migration guide](https://docs.gradle.org/current/userguide/migrating_from_groovy_to_kotlin_dsl.html) in the Gradle documentation.
+
+3. Add the proper ecosystem plugin
+
+The Declarative Gradle prototype maintains a KMP prototype plugin.
+As the `gradle-client` project is a Kotlin Multiplatform project, we added this plugin to the project's existing `settings.gradle.kts` file.
+Also, be sure to include the `gradlePluginPortal()` as a repository if your project doesn't already include this.
+
+
+```
+pluginManagement {
+    repositories {
+        gradlePluginPortal()
+    }
+}
+
+plugins {
+    id("org.gradle.experimental.kmp-ecosystem").version("0.1.41")
+}
+
+```
+
+4. Use the existing prototype plugin's software types to migrate basics
+
+Thing like declaring typical `implementation`, `api` and testing dependencies should be already supported out-of-the-box with the existing Software Types provided by Gradle's prototype plugins.
+Migrating your dependencies to these is a good test of your setup.
+Remember that Declarative Software Types can be used from KTS files.
+
+We added the following to the `gradle-client` project's `build.gradle.kts` file:
+
+
+```
+kotlinApplication {
+    targets {
+        jvm {
+            jdkVersion = 17
+
+            dependencies {
+                implementation(project(":build-action"))
+                implementation(project(":mutations-demo"))
+
+                implementation(project.dependencies.platform(libs.kotlin.bom))
+                implementation(project.dependencies.platform(libs.kotlinx.coroutines.bom))
+                implementation(project.dependencies.platform(libs.kotlinx.serialization.bom))
+                implementation(project.dependencies.platform(libs.ktor.bom))
+
+                implementation(libs.gradle.tooling.api)
+
+                implementation(libs.sqldelight.extensions.coroutines)
+                implementation(libs.sqldelight.runtime)
+
+                // ...
+            }
+        }
+    }
+}
+```
+
+And we _removed_ these dependencies from the `jvmMain.dependencies` block where they were previously declared.
+Set the org.gradle.kotlin.dsl.dcl flag in the project's properties file.
+Now the prototype plugin should be take care of wiring these dependencies into the appropriate configurations, and the project should continue to build and run without change.
+
+This represents the minimal configuration needed to make use of this `kotlinApplication` Software Type - which is why this snippet also declares the required JDK version information.
+
+Continue to do this for each of your dependencies.
+
+5. Setup an included build to define custom plugins
+
+We can't just continue to use the `kotlinApplication` plugin type.
+This type doesn't offer any support for SQL Delight, or Detekt, or other build configuration specific to this project.
+This type can't yet be combined with other Declarative Gradle features in an extensible way (support for Composition of Software Types and Software Type Features is being actively developed).
+We have to use an included build instead of `buildSrc` to contain the custom plugins.
+This is because `buildSrc` is built after the project's settings script is evaluated, so it can't contain `Plugin<Settings>` that are meant to be used in this build, and we will need to write one of those.
+
+... shows setup
+
+
+6. Create the new Plugins
+
+We can't use `extend` on the existing plugin class, because of a technicial limitation - each Software Type plugin can expose only a single software type.
+So we'll have to create some 
+
+... continues like this through basics of setting up the plugins
+
+7. Write new extensions per each "major domain type" - Detekt, SQLDelight, etc.
+
+Art more than science, etc.
+Test build with them empty
+Discuss dependency modifiers for `platform`
+
+8. Migrate buildscript to use new types
+Build should run, probably compile errors
+
+9. Wire plugins
+Discuss need for afterEvaluate...
+
+10. Delete everything non-declarative
+Convert files to DCL
+Build should still run
+
+## Remaining TODOs
+
+Discuss stuff we couldn't migrate.
+Discuss limitations (biggest is reliance on afterEvaluate if wiring plugins without lazy props)
+Discuss imports, unqualified enums, etc.
+
+## Conclusion
+
+There's no easy button, but it's not THAT hard...
+It’s really nice to add something to the extension interface, hit refresh, and then get type-safe assistance on it immediately in the project build...
+
+
+# Hints and Tips
+
+- Add `@file:Suppress("UnstableApiUsage")` to the top of your KTS files during the intermediate stages to silence warnings about many of the DCL types.
+- DCL does not yet support Version Catalogs, so if you're using one, you'll need to convert your `libs.my.lib` dependency declarations to GAV coordinates like `org:mylib:1.4` when you're ready to switch from using Kotlin DSL files with Software Types to fully declarative DCL files.  This is annoying, but temporary.
+- DCL files don't allow infix notation.  If you were applying plugins like:
+
+```
+    plugins {
+        id("my.plugin") version "0.4"
+    }
+```
+
+switch to using chained calls like:
+```
+    plugins {
+        id("my.plugin").version("0.4")
+    }
+```
+
+
+## Footguns
+- It’s easy to forget to set org.gradle.kotlin.dsl.dcl flag in properties, but this is necessary to use Software Type plugins in non-DCL (KTS) files.
+- NDOC discussion...
+- Using the wrong annotation types
+- Other stuff from my notes
+- Unnecessary brackets are actually necessary...
