This recipe is available under the Apache License Version 2.0.

Usage

This recipe has no required configuration parameters and comes from a rewrite core library. It can be activated directly without adding any dependencies.

OpenRewrite artifacts are distributed through the Code Genome Project repository (https://artifacts.codegenomeproject.org/maven), which requires authentication. Sign in to the Code Genome Project to create a download token, then in the snippets below replace USERNAME with the email or username you signed in with and TOKEN with that token. See the quickstart guide for details.

Gradle

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

   plugins {
       id("org.openrewrite.rewrite") version("latest.release")
   }
   
   rewrite {
       activeRecipe("org.openrewrite.java.search.ClasspathTypeCounts")
       setExportDatatables(true)
   }
   
   repositories {
       mavenCentral()
       maven {
           url = "https://artifacts.codegenomeproject.org/maven"
           credentials {
               username = "USERNAME"
               password = "TOKEN"
           }
       }
   }

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:7.39.0") }
   }
   rootProject {
       plugins.apply(org.openrewrite.gradle.RewritePlugin)
       dependencies {
           rewrite("org.openrewrite:rewrite-java")
       }
       rewrite {
           activeRecipe("org.openrewrite.java.search.ClasspathTypeCounts")
       setExportDatatables(true)
       }
       afterEvaluate {
           if (repositories.isEmpty()) {
               repositories {
                   mavenCentral()
               }
           }
           repositories {
               maven {
                   url = "https://artifacts.codegenomeproject.org/maven"
                   credentials {
                       username = "USERNAME"
                       password = "TOKEN"
                   }
               }
           }
       }
   }

2. Run the recipe.
   shell

   gradle --init-script init.gradle rewriteRun

Gradle init script (Kotlin)

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

   initscript {
       repositories {
           maven { url = uri("https://plugins.gradle.org/m2") }
       }
       dependencies { classpath("org.openrewrite:plugin:7.39.0") }
   }
   rootProject {
       plugins.apply(org.openrewrite.gradle.RewritePlugin::class.java)
       dependencies {
           add("rewrite", "org.openrewrite:rewrite-java")
       }
       extensions.configure<org.openrewrite.gradle.RewriteExtension> {
           activeRecipe("org.openrewrite.java.search.ClasspathTypeCounts")
       setExportDatatables(true)
       }
       afterEvaluate {
           if (repositories.isEmpty()) {
               repositories {
                   mavenCentral()
               }
           }
           repositories {
               maven {
                   url = uri("https://artifacts.codegenomeproject.org/maven")
                   credentials {
                       username = "USERNAME"
                       password = "TOKEN"
                   }
               }
           }
       }
   }

2. Run the recipe.
   shell

   gradle --init-script init.gradle.kts rewriteRun

Maven POM

1. Add the Code Genome Project credentials to your Maven settings.xml file (typically at ~/.m2/settings.xml):
   settings.xml

   <settings>
     <servers>
       <server>
         <id>codegenome</id>
         <username>USERNAME</username>
         <password>TOKEN</password>
       </server>
     </servers>
   </settings>

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

   <project>
     <repositories>
       <repository>
         <id>codegenome</id>
         <url>https://artifacts.codegenomeproject.org/maven</url>
       </repository>
     </repositories>
     <pluginRepositories>
       <pluginRepository>
         <id>codegenome</id>
         <url>https://artifacts.codegenomeproject.org/maven</url>
       </pluginRepository>
     </pluginRepositories>
     <build>
       <plugins>
         <plugin>
           <groupId>org.openrewrite.maven</groupId>
           <artifactId>rewrite-maven-plugin</artifactId>
           <version>6.46.1</version>
           <configuration>
             <exportDatatables>true</exportDatatables>
             <activeRecipes>
               <recipe>org.openrewrite.java.search.ClasspathTypeCounts</recipe>
             </activeRecipes>
           </configuration>
         </plugin>
       </plugins>
     </build>
   </project>

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

Maven Command Line

You will need to have Maven installed on your machine before you can run the following command. Since this approach leaves your pom.xml untouched, the Code Genome Project repository has to be declared in your Maven settings.xml file (typically at ~/.m2/settings.xml) instead: as a pluginRepository so that rewrite-maven-plugin itself can be resolved, and as a repository so that recipe artifacts passed to rewrite.recipeArtifactCoordinates can be resolved.

settings.xml

<settings>
  <servers>
    <server>
      <id>codegenome</id>
      <username>USERNAME</username>
      <password>TOKEN</password>
    </server>
  </servers>
  <profiles>
    <profile>
      <id>codegenome</id>
      <repositories>
        <repository>
          <id>codegenome</id>
          <url>https://artifacts.codegenomeproject.org/maven</url>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>codegenome</id>
          <url>https://artifacts.codegenomeproject.org/maven</url>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>codegenome</activeProfile>
  </activeProfiles>
</settings>

With those credentials in place you can run the recipe:

shell

mvn -U org.openrewrite.maven:rewrite-maven-plugin:6.46.1:run --define rewrite.activeRecipes=org.openrewrite.java.search.ClasspathTypeCounts --define rewrite.exportDatatables=true

Moderne CLI
