You can use either\n[Maven](https://maven.apache.org) or [Gradle](https://gradle.org) to manage\ndependencies for your Java Cloud Run functions.\n\nDeclaring and managing dependencies\n-----------------------------------\n\nYou can declare and manage dependencies using either Maven or Gradle:\n\n- To manage dependencies using Maven:\n\n - Specify the dependencies in the `\u003cdependencies\u003e` section inside the\n [`pom.xml`](http://maven.apache.org/guides/introduction/introduction-to-the-pom.html)\n file of your project.\n\n - To manage your project's dependency on Maven itself, you can use the\n [Maven Wrapper](https://maven.apache.org/wrapper/). If you don't use the\n Maven Wrapper, Cloud Run functions defaults to using a recent\n version of Maven when running [`gcloud functions deploy`](/sdk/gcloud/reference/functions/deploy).\n\n- To manage dependencies using Gradle, you specify the dependencies in the\n [`build.gradle`](https://docs.gradle.org/current/userguide/tutorial_using_tasks.html)\n file of your project.\n\nThe [Functions Framework](https://github.com/GoogleCloudPlatform/functions-framework-java)\nis a required dependency for all functions. Although\nCloud Run functions installs it on your behalf when the function\nis created, we recommend that you include it as an explicit dependency for\nclarity.\n\nIf your\nfunction relies on private dependencies, we recommend that you\nmirror `functions-framework` to your private registry. Include the mirrored\n`functions-framework` as a dependency to your function to avoid installing the\npackage from the public internet.\n\nUsing the Google Cloud Client Libraries for Java\n------------------------------------------------\n\n[Google Cloud Client Libraries for\nJava](https://github.com/googleapis/google-cloud-java) provide idiomatic access\nto Google Cloud services. To use a library, declare it as a dependency.\n\nTypically you only declare dependencies on the specific libraries that your\nfunction needs. For example: \n\n### Maven\n\n \u003cproject xmlns=\"http://maven.apache.org/POM/4.0.0\"\n xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n xsi:schemaLocation=\"http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd\"\u003e\n \u003cmodelVersion\u003e4.0.0\u003c/modelVersion\u003e\n\n \u003cgroupId\u003ecom.example.functions\u003c/groupId\u003e\n \u003cartifactId\u003efunctions-hello-world\u003c/artifactId\u003e\n \u003cversion\u003e1.0.0-SNAPSHOT\u003c/version\u003e\n \u003cproperties\u003e\n \u003cmaven.compiler.target\u003e11\u003c/maven.compiler.target\u003e\n \u003cmaven.compiler.source\u003e11\u003c/maven.compiler.source\u003e\n \u003c/properties\u003e\n\n \u003cdependencies\u003e\n \u003c!-- Required for Function primitives --\u003e\n \u003cdependency\u003e\n \u003cgroupId\u003ecom.google.cloud.functions\u003c/groupId\u003e\n \u003cartifactId\u003efunctions-framework-api\u003c/artifactId\u003e\n \u003cversion\u003e1.1.0\u003c/version\u003e\n \u003cscope\u003eprovided\u003c/scope\u003e\n \u003c/dependency\u003e\n \u003c/dependencies\u003e\n\n \u003cbuild\u003e\n \u003cplugins\u003e\n \u003cplugin\u003e\n \u003c!--\n Google Cloud Functions Framework Maven plugin\n\n This plugin allows you to run Cloud Functions Java code\n locally.
