How to use bom project in application project which import convention plugin?

Help/Discuss

Description

The sample code contains 3 projects.

  • “platform-bom” is a java-platform type which constraints the dependencies

  • “build-logic” is build logical type which defined a plugin named ‘com.example.my-plugin’. In plugin we define a dependency on platform-bom with maven GAV.

  • “app” is a application type project which use the com.example.my-plugin plugin

Run command

./gradlew run

Add the missing n :slight_smile:

Yes, I have changed ‘implemetation’ to ‘implementation’.
And I changed the POST content. You can find the ERROR LOG part.
But it will get the other problem that I just want to ask.

I will update my attachment.

The ‘com.example:platform-bom’ dependency constraints 'jakarta.inject:jakarta.inject-api:2.0.1' jar file.
But I have to defined the depenpendcy in plugin in build-logic project. This plugin is used in application project app.

dependencies {
  implementation platform("${project.group}:platform-bom:${project.version}") 
}

Is it wrong or not properly?

While you should include build-logic with pluginManagement { ... } as it contributes plugins (and must be done there if you also add some settings plugin), your platform-bom project is nowhere included. And the error about inject-api is as it states. You define a dependency on it, but have no repositories defined. This wouldn’t have changed even if the BOM would be found.

Thanks a lot! I will try it .

I have following three changes :

  • settings.gradle
    add the ‘platform-bom’ module.

    rootProject.name="main"  
includeBuild('build-logic') 
include 'app', 'platform-bom'

  • build-logic\src\main\groovy\com.example.my-plugin.gradle

    dependencies {
//  implementation platform("${project.group}:platform-bom:${project.version}")
  implementation(platform(project(":platform-bom")))
}

  • platform-bom\build.gradle

      dependencies {
      constraints {
          api('jakarta.inject:jakarta.inject-api:2.0.1')
      }
  }

Finally, it’s work.
