Amper 0.10 is becoming JetBrains’ next-generation build entry point
Amper is JetBrains’ experimental build and configuration tool for Kotlin and Java. Unlike Gradle, which expresses build logic through a DSL, Amper attempts to describe project structure, dependencies, platforms, and toolchains through a more stable and machine-parsable YAML model.
The core pain point it addresses is straightforward: KMP and Android projects keep getting more complex, and build.gradle.kts files have gradually evolved into “half a program.” Once configuration can contain logic and lifecycle hooks, both IDEs and AI systems have a harder time understanding the project accurately.
Amper 0.10 focuses its key updates on closing the build workflow loop
Version 0.10 sends a clear signal: Amper is no longer just a thin layer on top of Gradle. It is evolving toward an independent build entry point. The most notable capabilities include automatic JDK provisioning, Maven project conversion, support for third-party Kotlin compiler plugins, and a complete default toolchain definition.
product:
type: app # Declare the current artifact type as an application
platforms:
- android # Declare the Android platform
- ios # Declare the iOS platform
dependencies:
- xxx # Declare shared dependenciesThis configuration snippet demonstrates Amper’s core value: it compresses a “programmable build script” into an “inferable project model.”
The YAML declarative model is better aligned with the multiplatform and AI era
Gradle’s power comes from its programmable DSL, but that flexibility comes at a cost: configuration can easily spiral out of control. In KMP projects especially, platform matrices, source set splits, CI environments, and plugin coordination can cause scripts to grow rapidly.
Amper takes the opposite path: it limits configuration freedom in exchange for stronger consistency, better visualization, and more reliable autocompletion. This approach is friendlier to IDEs, code analysis tools, and AI systems because project structure is no longer hidden inside dynamic scripts.
AI Visual Insight: This image shows how Amper is evolving from a Gradle-attached configuration layer into an independent CLI and standalone project model. It emphasizes that Amper is no longer just syntactic sugar, but a new build entry point and toolchain control plane.
AI Visual Insight: This image visually explains how Amper is positioned as a new abstraction layer for Kotlin, KMP, and Android build workflows. It sits between the IDE, CLI, and project model, serving as a unified configuration and execution entry point.
Automatic JDK provisioning directly reduces environment drift
JDK provisioning is one of the most important features in Amper 0.10. It allows the tool to automatically download and install a matching JDK. Amper uses JDK 21 by default, while also allowing teams to declare an explicit version in module.yaml.
That means a new team member can clone the project without first manually aligning a local JDK, Gradle version, and plugin environment. For team collaboration and CI, the consistency benefits are much greater than the syntactic simplification alone.
jdk:
version: 21 # Specify the required JDK version for the projectThis snippet elevates environment requirements into the project model itself rather than leaving them as informal documentation.
Amper is systematically covering Gradle’s core responsibilities
From the update trajectory between 2024 and 2026, Amper is filling in project modeling, Compose resources, KSP2, Android release builds, run/test UX, compiler plugins, and JDK provisioning. These capabilities map closely to the most important build responsibilities in modern Android projects.
AI Visual Insight: This image reflects how Amper simplifies the declarative project model by pulling modules, platforms, and dependencies out of a script-based DSL and turning them into structured fields, reducing both comprehension and maintenance costs.
AI Visual Insight: This image further illustrates Amper’s unified view of multiplatform configuration, showing that Android, iOS, and shared dependencies can all be described within a single consistent project model.
If Gradle’s advantage is that it is “flexible enough,” Amper’s advantage is that it is “controllable enough.” For modern Kotlin multiplatform projects, the latter offers stronger long-term value in collaboration, migration, and tool integration.
Maven-to-Amper conversion lowers the barrier to adoption
Amper 0.10 can already read an existing pom.xml and generate project.yaml and module.yaml. This capability does not directly change build performance, but it significantly lowers migration cost and allows teams to create a proof of concept quickly from an existing Java or Maven project.
amper import pom.xml # Generate Amper project files from Maven configuration
amper build # Run the build
amper test # Run the test suiteThis command set reflects the complete CLI experience Amper wants to offer: import, build, and test all handled through one unified entry point.
Amper does not fully replace Gradle yet, but the direction is already clear
At its current stage, Amper 0.10 is not yet a mature replacement, especially for large Android projects with significant legacy constraints and complex plugin ecosystems. In those environments, Gradle still holds a decisive advantage.
However, in JetBrains-led Kotlin, KMP, Compose, and Android scenarios, Amper has already shown a clear path toward taking over key build responsibilities. It represents a different engineering philosophy: replace script-driven builds with a declarative model, and replace manual toolchain assembly with tighter toolchain integration.
AI Visual Insight: This image highlights automatic JDK download, version matching, and environment management workflows, showing that Amper is trying to make “project runnability” a built-in tool capability instead of a manual developer responsibility.
AI Visual Insight: This image summarizes Amper’s path toward covering build responsibilities, including project structure, resources, code generation, release workflows, and testing, indicating that it is expanding from isolated features into a system-level build platform.

The FAQ section answers the most practical questions
Q1: Is Amper 0.10 ready for immediate production use?
It is not advisable to replace all production projects right away. Amper is better suited to new Kotlin or KMP projects, internal pilots, or technical evaluation efforts because its direction is clear, but its ecosystem and stability are still evolving.
Q2: What is Amper’s biggest advantage over Gradle?
Its biggest advantage is not that it is “more powerful,” but that it is “more understandable.” Declarative YAML configuration, a unified project model, and automatic JDK management significantly reduce the cognitive load and environment overhead of multiplatform projects.
Q3: Why is Amper more friendly to AI and IDEs?
Because it deemphasizes dynamic DSL and script logic, and turns modules, platforms, dependencies, and toolchains into structured fields. That makes static analysis easier and improves the quality of autocompletion, refactoring, and migration suggestions.
Core Summary: Amper 0.10 marks a new phase in JetBrains’ experimental build tool strategy for Kotlin, Java, KMP, and Android. With declarative YAML configuration, automatic JDK provisioning, Maven conversion, and compiler plugin support at its core, it is steadily expanding into the key responsibilities that Gradle currently owns in multiplatform projects.
