Version catalogs should work in buildscript dependencies

[swankjesse]

This was previously reported as part 2 of Issue 16652.

Expected Behavior

I expect centralized dependency versions to work everywhere I specify dependencies. This includes my buildscript clause.

In myproject/settings.gradle.kts:

enableFeaturePreview("VERSION_CATALOGS")
...

In myproject/gradle/libs.versions.toml:

[libraries]
shadowJarPlugin = "com.github.jengelman.gradle.plugins:shadow:6.1.0"

In myproject/build.gradle.kts:

buildscript {
  dependencies {
    classpath(libs.shadowJarPlugin)
  }
}
...

Current Behavior

> Configure project :
e: /Users/jwilson/Development/myproject/build.gradle.kts:20:15: Unresolved reference: libs

Context

I’m using Gradle 7.

Workaround

This is a workaround. It is verbose, doesn’t have IDE support, and is inconsistent with my other dependencies blocks.

buildscript {
  fun libs(lib: String): String {
    val versionCatalog = project.extensions.getByType(VersionCatalogsExtension::class).named("libs")
    val dep = versionCatalog.findDependency(lib).get().get()
    return "${dep.module.group}:${dep.module.name}:${dep.versionConstraint.displayName}"
  }

  dependencies {
    classpath(libs("shadowJarPlugin"))
  }
}

Better workaround that allows for typesafely accessing the versions:

buildscript {
  repositories {
    gradlePluginPortal()
    google()
    mavenCentral()
  }
  dependencies {
    val libs = project.extensions.getByType<VersionCatalogsExtension>().named("libs") as org.gradle.accessors.dm.LibrariesForLibs
    classpath(libs.sqlDelight.gradlePlugin)
  }
}

I have a similar problem, but in a different place. I tried to define dependencies from service catalog for sub-projects and it does not work either.

Example:

subprojects {
   dependencies {
      implementation(libs.abc)
   }
}

Extension with name 'libs' does not exist. Currently registered extension names: ...

Looks like you're having this issue, which is unrelated

@swankjesse Is this feature VERSION CATALOG supported by Android Studio? I tried it but autocomplete ain't working.

What version of Gradle should this fix show up in? (I just tested Gradle 7.1 and this seems to still be broken)

[krzdabrowski]

I just tested it too with 7.1 and it doesn't work yet. I guess it was fixed too late to come into 7.1. And also some docs for that feature are waiting for review. Hopefully it will be included in next release.

EDIT: it will be in 7.2, see milestones.

Can you write a proper issue description? "Sill not working" is very hard to debug.
