Android Gradle Plugin 8.13.1 Gradle 9.2.1 compatibility official documentation

💡 Result:

Yes, Android Gradle Plugin (AGP) 8.13.1 is compatible with Gradle 9.2.1 [1]. Official documentation from Gradle indicates that Gradle 9.2.1 has been tested and is compatible with Android Gradle Plugin versions ranging from 8.4 through 8.13 [1]. While AGP 8.x series was primarily designed for Gradle 8.x, Gradle maintained support for these plugin versions in the 9.x series up to version 9.5 [2]. For your specific configuration: - Android Gradle Plugin 8.13.1 [3] - Gradle 9.2.1 [1] This combination falls within the supported range verified by the Gradle compatibility matrix [1]. As a general best practice, it is recommended to keep both your plugin and Gradle wrapper updated to their latest stable versions to ensure optimal performance and security [4].

site:developer.android.com/build/releases Android Gradle Plugin 9.0 Gradle 9.1 compatibility

💡 Result:

Android Gradle Plugin (AGP) 9.0 is compatible with Gradle 9.1.0 and higher [1]. Specifically, AGP 9.0 requires a minimum Gradle version of 9.1.0 [2][1]. For the best performance and compatibility, it is recommended to use the latest versions of both the Android Gradle Plugin and Gradle [1]. As of August 2026, later versions of AGP are available, such as AGP 9.1.1, which requires a minimum Gradle version of 9.3.1 [3][4], and AGP 9.4.0, which requires Gradle 9.6.0 [5].

Gradle plugin request already on classpath with a different version buildscript plugins block Android Gradle Plugin

💡 Result:

The error "Plugin request for plugin already on the classpath must not include a version" occurs in Gradle when a plugin is requested with a version in a plugins block, but that plugin is already present on the build classpath (e.g., loaded by the root project, buildSrc, or pluginManagement blocks) [1][2]. Because Gradle does not allow multiple versions of the same plugin to exist in the same build, it rejects any request that attempts to define a version when one is already established [1][3]. To resolve this issue, follow these standard practices: 1. Define the Version Once: Centralize the plugin version in your root build.gradle.kts file or in settings.gradle.kts using the pluginManagement block [1][3]. 2. Use apply false in the Root: When defining the version in the root project, use apply false to add the plugin to the classpath without applying it to the root project itself [1][4][3]. kotlin // In root build.gradle.kts plugins { id("com.android.application") version "8.x.x" apply false } 3. Omit the Version in Subprojects: In your module-level build.gradle.kts files, apply the plugin without specifying the version [1][4][3]. This tells Gradle to use the version already available on the classpath [4]. kotlin // In module build.gradle.kts plugins { id("com.android.application") } If you are using Version Catalogs (libs.versions.toml), this issue often arises when using alias(libs.plugins.xxx) in modules, as alias typically includes the version [5][4]. In such cases, if the plugin is already on the classpath, you may need to use id to reference the plugin ID directly instead of using the alias, or ensure the version is only defined in the root where it is first applied [5][6][4]. For the Android Gradle Plugin (AGP), strictly enforce the same version across all modules and included builds [7]. AGP contains internal logic that specifically checks for version consistency and will throw an error if multiple versions are detected within the same build process [7].

site:docs.gradle.org plugin already on the classpath with a different version

💡 Result:

The error "plugin already on the classpath with a different version" typically occurs in build tools like Gradle when a project attempts to load the same plugin with conflicting version requirements [1]. Because plugins share the same classloader, Gradle and other build systems cannot safely load two different versions of the same plugin simultaneously [1]. To troubleshoot and resolve this issue, consider the following approaches based on the dependency graph: 1. Identify the Conflict: Use built-in diagnostic tools to understand where the conflicting versions are coming from. In Gradle, the dependencyInsight task is the primary tool for this [2]. You can run:./gradlew dependencyInsight --configuration <configuration_name> --dependency <plugin_id> This report will show you the "Selection reasons," identifying which parts of your project or transitive dependencies are requesting the different versions [2]. 2. Align Plugin Versions: The most common fix is to ensure all parts of your build configuration request the same version of the plugin [3][4]. If a transitive dependency is pulling in an older or different version, you can force a specific version in your top-level build script or settings file to override it [3][5]. 3. Use Plugin Management: If you are managing multiple sub-projects, define the plugin versions in your settings.gradle (or settings.gradle.kts) file using the pluginsManagement block [6]. This centralizes the version definition, preventing individual modules from accidentally requesting conflicting versions [6]. 4. Check for Capability Conflicts: In some cases, the error relates to "capabilities" where different modules (or different versions of the same relocated module) provide the same feature [7][8]. If this is the cause, you may need to use component metadata rules to explicitly declare them as mutually exclusive or choose a preferred implementation [7][9]. If you are developing a plugin, be aware that plugins can introduce complex dependency graphs [1]. Ensure that your plugin does not transitively include a version of itself or a core library that conflicts with the host project's requirements [1].
