BOM Migration — Gradle Programmatic Version Catalog (settings.gradle)

Some projects define version catalogs programmatically in settings.gradle / settings.gradle.kts instead of using a TOML file. OpenRewrite does not support this either (openrewrite/rewrite#4852). Handle manually.

Step 0 — Detect programmatic catalog usage

Look for a dependencyResolutionManagement block in settings.gradle or settings.gradle.kts:

// settings.gradle (Groovy DSL)
dependencyResolutionManagement {
    versionCatalogs {
        libs {
            version("azureSdk", "1.41.4")
            version("azureStorage", "8.6.6")
            library("azure", "com.microsoft.azure", "azure").versionRef("azureSdk")
            library("azure-storage", "com.microsoft.azure", "azure-storage").versionRef("azureStorage")
        }
    }
}

// settings.gradle.kts (Kotlin DSL)
dependencyResolutionManagement {
    versionCatalogs {
        create("libs") {
            version("azureSdk", "1.41.4")
            version("azureStorage", "8.6.6")
            library("azure", "com.microsoft.azure", "azure").versionRef("azureSdk")
            library("azure-storage", "com.microsoft.azure", "azure-storage").versionRef("azureStorage")
        }
    }
}

The library() call can also use the two-arg module form (the same syntax applies to Kotlin DSL):

library("azure", "com.microsoft.azure:azure").versionRef("azureSdk")
library("azure-inline", "com.microsoft.azure:azure").version("1.41.4")

If the project has this pattern and contains Azure dependency entries, use this section. The same libs.<alias> accessor syntax is used in build.gradle as with TOML catalogs.

Step 1 — Add or upgrade the BOM

Add a version and library entry for the BOM inside the versionCatalogs block:

// Groovy DSL
dependencyResolutionManagement {
    versionCatalogs {
        libs {
            version("azureSdkBom", "{bom_version}")
            library("azure-sdk-bom", "com.azure", "azure-sdk-bom").versionRef("azureSdkBom")
        }
    }
}

// Kotlin DSL
dependencyResolutionManagement {
    versionCatalogs {
        create("libs") {
            version("azureSdkBom", "{bom_version}")
            library("azure-sdk-bom", "com.azure", "azure-sdk-bom").versionRef("azureSdkBom")
        }
    }
}

If a BOM entry already exists, update the version string.

Add the platform dependency (if not already present).

Groovy DSL (build.gradle):

dependencies {
    implementation enforcedPlatform(libs.azure.sdk.bom)
}

Kotlin DSL (build.gradle.kts):

dependencies {
    implementation(enforcedPlatform(libs.azure.sdk.bom))
}

Step 2 — Remove explicit versions from BOM-managed Azure libraries

For each modern Azure library (com.azure.*) managed by the BOM, change its catalog entry to remove the version. Use the withoutVersion() call:

The snippets below show Groovy DSL (settings.gradle); the same code applies to Kotlin DSL (settings.gradle.kts).

Before:

library("azure-identity", "com.azure", "azure-identity").versionRef("azureIdentity")

After:

library("azure-identity", "com.azure", "azure-identity").withoutVersion()

For the two-arg module form (the same syntax applies to Kotlin DSL):

// Before
library("azure-identity", "com.azure:azure-identity").versionRef("azureIdentity")
// After
library("azure-identity", "com.azure:azure-identity").withoutVersion()

Then remove any orphaned version(...) calls that are no longer referenced.

Step 3 — Replace legacy Azure library entries with modern equivalents

For each legacy com.microsoft.azure.* library call:

1. Replace the group and artifact with the modern com.azure.* equivalent.
2. Change .versionRef(...) or .version(...) to .withoutVersion() if the new artifact is managed by the BOM.
3. Remove orphaned version(...) calls.
4. If you rename the alias (first argument), update all references in build.gradle / build.gradle.kts and any bundle(...) calls.

The snippets below show Groovy DSL (settings.gradle); the same code applies to Kotlin DSL (settings.gradle.kts).

Before:

version("azureSdk", "1.41.4")
version("azureStorage", "8.6.6")
library("azure", "com.microsoft.azure", "azure").versionRef("azureSdk")
library("azure-storage", "com.microsoft.azure", "azure-storage").versionRef("azureStorage")

After:

library("azure-resourcemanager", "com.azure.resourcemanager", "azure-resourcemanager").withoutVersion()
library("azure-storage-blob", "com.azure", "azure-storage-blob").withoutVersion()

Then update build.gradle (Groovy DSL):

// Before
implementation libs.azure
implementation libs.azure.storage

// After
implementation libs.azure.resourcemanager
implementation libs.azure.storage.blob

Or build.gradle.kts (Kotlin DSL):

// Before
implementation(libs.azure)
implementation(libs.azure.storage)

// After
implementation(libs.azure.resourcemanager)
implementation(libs.azure.storage.blob)

Step 4 — Handle bundles

If bundle(...) calls reference any renamed or removed aliases, update them:

Groovy DSL (settings.gradle):

// Before
bundle("azureLibs", ["azure", "azure-storage"])
// After
bundle("azureLibs", ["azure-resourcemanager", "azure-storage-blob", "azure-identity"])

Kotlin DSL (settings.gradle.kts):

// Before
bundle("azureLibs", listOf("azure", "azure-storage"))
// After
bundle("azureLibs", listOf("azure-resourcemanager", "azure-storage-blob", "azure-identity"))

Expected settings.gradle after migration

Groovy DSL (settings.gradle):

dependencyResolutionManagement {
    versionCatalogs {
        libs {
            version("azureSdkBom", "{bom_version}")
            library("azure-sdk-bom", "com.azure", "azure-sdk-bom").versionRef("azureSdkBom")
            library("azure-identity", "com.azure", "azure-identity").withoutVersion()
            library("azure-resourcemanager", "com.azure.resourcemanager", "azure-resourcemanager").withoutVersion()
        }
    }
}

Kotlin DSL (settings.gradle.kts):

dependencyResolutionManagement {
    versionCatalogs {
        create("libs") {
            version("azureSdkBom", "{bom_version}")
            library("azure-sdk-bom", "com.azure", "azure-sdk-bom").versionRef("azureSdkBom")
            library("azure-identity", "com.azure", "azure-identity").withoutVersion()
            library("azure-resourcemanager", "com.azure.resourcemanager", "azure-resourcemanager").withoutVersion()
        }
    }
}
