Dependency resolution diagnostic

org.openrewrite.java.dependencies.DependencyResolutionDiagnostic

_Recipes which manipulate dependencies must be able to successfully access the artifact repositories and resolve dependencies from them. This recipe produces two data tables used to understand the state of dependency resolution.

The Repository accessibility report lists all the artifact repositories known to the project and whether respond to network access. The network access is attempted while the recipe is run and so is representative of current conditions.

The Gradle dependency configuration errors lists all the dependency configurations that failed to resolve one or more dependencies when the project was parsed. This is representative of conditions at the time the LST was parsed._

Recipe source

GitHub, Issue Tracker, Maven Central

• groupId: org.openrewrite.recipe

• artifactId: rewrite-java-dependencies

• version: 1.7.0

Options

Type	Name	Description	Example
String	groupId	Optional. The group ID of a dependency to attempt to download from the repository. Default value is "com.fasterxml.jackson.core". If this dependency is not found in the repository the error will be noted in the report. There is no need to specify an alternate value for this parameter unless the repository is known not to contain jackson-core.	com.fasterxml.jackson.core
String	artifactId	Optional. The artifact ID of a dependency to attempt to download from the repository. Default value is "jackson-core". If this dependency is not found in the repository the error will be noted in the report. There is no need to specify an alternate value for this parameter unless the repository is known not to contain jackson-core.	jackson-core
String	version	Optional. The version of a dependency to attempt to download from the repository. Default value is "2.16.0". If this dependency is not found in the repository the error will be noted in the report. There is no need to specify an alternate value for this parameter unless the repository is known not to contain jackson-core.	2.16.0

Data Tables (Only available on the Moderne platform)

Repository accessibility report

Listing of all dependency repositories and whether they are accessible.

Column Name	Description
Repository URI	The URI of the repository
Ping exception type	Empty if the repository responded to a ping. Otherwise, the type of exception encountered when attempting to access the repository.
Ping error message	Empty if the repository was accessible. Otherwise, the error message encountered when attempting to access the repository.
Ping HTTP code	The HTTP response code returned by the repository. May be empty for non-HTTP repositories.
Dependency resolution exception type	Empty if ping failed, or if the repository successfully downloaded the specified dependency. Otherwise, the type of exception encountered when attempting to access the repository.
Dependency resolution error message	Empty if ping failed, or if the repository successfully downloaded the specified dependency. Otherwise, the error message encountered when attempting to access the repository.

Gradle dependency configuration errors

Records Gradle dependency configurations which failed to resolve during parsing. Partial success/failure is common, a failure in this list does not mean that every dependency failed to resolve.

Column Name	Description
Project path	The path of the project which contains the dependency configuration.
Configuration name	The name of the dependency configuration which failed to resolve.
Exception type	The type of exception encountered when attempting to resolve the dependency configuration.
Error message	The error message encountered when attempting to resolve the dependency configuration.

Usage

This recipe has no required configuration options. It can be activated by adding a dependency on org.openrewrite.recipe:rewrite-java-dependencies:1.7.0 in your build file or by running a shell command (in which case no build changes are needed):

Gradle

1. Add the following to your build.gradle file:

build.gradle

plugins {
    id("org.openrewrite.rewrite") version("6.12.0")
}

rewrite {
    activeRecipe("org.openrewrite.java.dependencies.DependencyResolutionDiagnostic")
}

repositories {
    mavenCentral()
}

dependencies {
    rewrite("org.openrewrite.recipe:rewrite-java-dependencies:1.7.0")
}

2. Run gradle rewriteRun to run the recipe.

Gradle init script

1. Create a file named init.gradle in the root of your project.

init.gradle

initscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2" }
    }
    dependencies { classpath("org.openrewrite:plugin:6.12.0") }
}
rootProject {
    plugins.apply(org.openrewrite.gradle.RewritePlugin)
    dependencies {
        rewrite("org.openrewrite.recipe:rewrite-java-dependencies:1.7.0")
    }
    rewrite {
        activeRecipe("org.openrewrite.java.dependencies.DependencyResolutionDiagnostic")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
            }
        }
    }
}

2. Run gradle --init-script init.gradle rewriteRun to run the recipe.

Maven POM

1. Add the following to your pom.xml file:

pom.xml

<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>5.29.0</version>
        <configuration>
          <activeRecipes>
            <recipe>org.openrewrite.java.dependencies.DependencyResolutionDiagnostic</recipe>
          </activeRecipes>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>org.openrewrite.recipe</groupId>
            <artifactId>rewrite-java-dependencies</artifactId>
            <version>1.7.0</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>

2. Run mvn rewrite:run to run the recipe.

Maven Command Line
