I am trying to set up a gradle multi-project build with all common build configuration packaged as convention plugins in a separate buildlogic directory, which is handled as an included build as described here.

As I have understood, the benefit of using an included build over buildSrc is that I can have multiple plugins as separate subprojects, so that a change in one plugin only affects those modules of the main build that actually use this plugin (instead of rebuilding everything upon a change to buildSrc).

Now, my problem is the following: Even though I implement separate convention plugins – say, one for libraries and one for applications – there is some common build logic for all. Therefore, I want to define a common plugin and include this plugin in both the library and app plugins.

My project structure looks as follows

my-project
|- settings.gradle.kts
|- buildlogic
   |- settings.gradle.kts
   |- common
      |- build.gradle.kts
      |- src/main/kotlin
                  |- buildlogicmon.gradle.kts
   |- library
      |- build.gradle.kts
      |- src/main/kotlin
                  |- buildlogic.library.gradle.kts
   |- app
      |- build.gradle.kts
      |- src/main/kotlin
                  |- buildlogic.app.gradle.kts
|- module-a // uses the library plugin
|- module-b // uses the app plugin
|... // more modules, gradle wrapper, etc.

I expect to include the common plugin in both buildlogic.library.gradle.kts and buildlogic.app.gradle.kts as follows:

plugins {
    id("buildlogic-common")
}
...

However, gradle complains that it can't find the plugin. What am I doing wrong? Which is the correct way to include one conventions from another one in an included build with plugins as subprojects?

In order a plugin in one subproject of an included build to apply another, it needs to depend on the build of the latter.

So if buildlogic.library wants to use buildlogicmon, then in its build.gradle.kts it needs to write:

// buildlogic/library/build.gradle.kts

dependencies {
    implementation(project(":common"))
}
