Build Gradle Files - Project and App Module

Using alias in the project-level build.gradle.kts and id in the module-level build.gradle.kts does not create any conflict.

These two mechanisms are complementary, not contradictory.

⁠

Why This Works

Aliases in Project-Level build.gradle.kts:

Aliases are typically used when your project employs a version catalog (libs.versions.toml file) to centralize dependency and plugin management.

By using alias, you can map plugins (like android.application) to a predefined alias in your catalog for easier version management.

Example:

alias(libs.plugins.android.application) apply false

This alias references a plugin and its version defined in libs.versions.toml.

Direct IDs in Module-Level build.gradle.kts:

Module-level build.gradle.kts files use the id syntax to explicitly apply plugins to specific modules.

Example:

kotlin

Copy code

plugins {

id("com.android.application")

id("org.jetbrains.kotlin.android")

}

This is where the actual plugins are applied to build the module.

Separation of Concerns:

Project-Level: Defines plugin availability across the entire project. Using apply false ensures plugins are available but not automatically applied.

Module-Level: Decides which plugins are actually applied to each specific module.

⁠

When Conflicts May Occur

Conflicts can occur only if:

Version Mismatches:

If the version specified in libs.versions.toml for the alias does not match the version hardcoded in the module-level build.gradle.kts.

Redundant Plugin Applications:

If you apply the same plugin in both the project-level and module-level files without proper scoping.

⁠

How to Ensure No Conflict

Check Version Consistency:

Ensure that versions defined in libs.versions.toml align with what the module requires.

Example of libs.versions.toml:

[plugins]

android.application = { id = "com.android.application", version = "8.1.1" }

kotlin.android = { id = "org.jetbrains.kotlin.android", version = "1.9.10" }

Avoid Double Application:

Use apply false in the project-level file to make plugins available globally without applying them.

Sync Gradle:

After setting aliases and applying plugins, sync the project to ensure everything works as expected.

Conclusion

Using alias in the project-level build.gradle.kts and id in the module-level file is standard practice in modern Android projects and will not create conflicts if managed correctly. It ensures modularity and clean separation of plugin definitions and usage.
