jf mvn

Run Maven builds with Artifactory integration for dependency resolution and build information collection.

This topic covers the following tasks:

• Configure Maven for Artifactory (jf mvn-config)
• Run Maven builds (jf mvn)

When to Use

Use jf mvn if your Java project uses Apache Maven (pom.xml) for builds and you want dependencies resolved from Artifactory with build-info collection. For Gradle-based projects, use jf gradle.

Running jf mvn instead of native mvn provides:

• Artifactory dependency resolution: Dependencies are fetched from your Artifactory Maven repositories, caching them for your organization
• Build-info collection: When using --build-name and --build-number, the CLI records resolved dependencies and produced artifacts
• Xray integration: Build info connects to JFrog Xray for vulnerability scanning of your dependency tree

If you don't need these features, use native mvn pointed at Artifactory via settings.xml.

Prerequisites

• Run jf mvn-config in the project directory before the first build.
• Configure a server with jf config add or jf c add.
• Authentication to Artifactory is required.

Configuration: jf mvn-config

Generate Maven build configuration for resolving and deploying artifacts through Artifactory. Run this once per project before your first build.

To configure Maven for Artifactory:

jf mvn-config [options]

Aliases: mvnc

jf mvn-config --help

Non-Interactive Configuration

Configure Maven with non-interactive flags:

jf mvn-config --server-id-resolve=<server-id> --repo-resolve-releases=<repo-name> --repo-resolve-snapshots=<repo-name> --server-id-deploy=<server-id> --repo-deploy-releases=<repo-name> --repo-deploy-snapshots=<repo-name>

Where:

• <server-id>: The server ID configured using jf config add
• <repo-name>: The name of the repository in Artifactory

For example:

jf mvn-config --server-id-resolve=my-server --repo-resolve-releases=libs-release --repo-resolve-snapshots=libs-snapshot --server-id-deploy=my-server --repo-deploy-releases=libs-release-local --repo-deploy-snapshots=libs-snapshot-local

Why Run Config First?

You must run jf mvn-config before running jf mvn. The config command creates a .jfrog/projects/maven.yaml file in your project directory that tells the CLI which Artifactory repositories to use for resolution and deployment. Without it, jf mvn does not know where to fetch or deploy artifacts.

If you skip this step, you will see the error: no config file was found! Before running the 'jf mvn' command on a project for the first time, the project should be configured with the 'jf mvn-config' command.

Shortcut: In CI/CD, pass all flags non-interactively so the config step is fully automated and reproducible.

Configuration Notes

• Run once per project: The configuration is stored in .jfrog/projects/maven.yaml in your project directory. You only need to run this once (or when changing repository assignments).
• Global vs project: Use --global to apply the configuration for all Maven projects on the machine. Without it, the configuration is project-specific.
• Snapshot policy: --snapshots-update-policy controls how often Maven checks for newer snapshot versions. Values: always, daily (default), interval:N (minutes), never.
• Wrapper support: Use --use-wrapper if your project uses the Maven wrapper (mvnw).

Expected Output

$ jf mvn-config --server-id-resolve=my-server --repo-resolve-releases=libs-release --repo-resolve-snapshots=libs-snapshot --server-id-deploy=my-server --repo-deploy-releases=libs-release-local --repo-deploy-snapshots=libs-snapshot-local
Maven build configuration saved successfully.

How to Verify

After running, confirm the configuration exists:

cat .jfrog/projects/maven.yaml

Build: jf mvn

Run Maven build with Artifactory integration for dependency resolution and build information collection.

To run a Maven build with Artifactory integration:

Synopsis

jf mvn <goals-and-options> [options]

Aliases: none

Arguments

Build Options

Build Examples

Build and Publish Build Information

jf mvn clean install --build-name=<build-name> --build-number=<build-number>

Where:

• <build-name>: A name for the build (for example, my-java-app)
• <build-number>: A number or identifier for the build run (for example, 1)

For example:

jf mvn clean install --build-name=my-java-app --build-number=1

Build with Custom Threads

jf mvn package --build-name=my-app --build-number=1 --threads=5

Build Without Deploying Artifacts

jf mvn clean install -Dartifactory.publish.artifacts=false

Important Notes

• Build-info publishing: Using --build-name and --build-number only collects build info. To publish it to Artifactory, run jf rt build-publish <name> <number> afterward.
• Maven goals: All standard Maven goals and flags work (clean, install, deploy, -DskipTests, -f, and others). The CLI wraps the native Maven execution.
• Thread count: The --threads flag controls parallel upload of build artifacts to Artifactory, not Maven's own -T parallelism.
• Hidden flag — --module: The --module flag is functional and collected by the build-info framework, but does not appear in jf mvn --help output. It works when passed on the command line alongside --build-name and --build-number.

Deploying Maven Artifacts

When you run Maven through JFrog CLI (jf mvn), the JFrog Build Info Extractor automatically deploys build artifacts to Artifactory. Unlike standard Maven, where deployment only occurs during the deploy phase, the JFrog CLI integration deploys artifacts at the install phase or later.

Preventing Deployment

To run Maven through JFrog CLI without deploying artifacts to Artifactory, use one of the following methods:

• Add the publish flag — Pass -Dartifactory.publish.artifacts=false to your goals/options:

jf mvn clean install -Dartifactory.publish.artifacts=false

• Use an earlier goal — Run jf mvn clean package instead of install if you only need to build without deploying.
• Omit deployment repositories — When configuring the project with jf mvn-config, do not specify --repo-deploy-releases or --repo-deploy-snapshots. If no deployment repositories are configured, artifacts will not be deployed.

Native Mode

Maven supports Native Mode, which bypasses jf mvn-config and all .jfrog/ YAML configuration. In this mode, no settings.xml is injected — you must configure Maven to resolve from Artifactory manually (via Set Me Up). Build-info is still collected when --build-name and --build-number are provided.

Enable with: export JFROG_RUN_NATIVE=true

For full setup instructions, per-tool comparison, and when to use each mode, see Native Mode.

Performance Notes

• Large multi-module projects: Maven builds with many modules generate significant build-info. The --threads flag controls upload parallelism for artifacts, not Maven's own -T thread count. Use both for maximum performance.
• Snapshot resolution frequency: If builds are slow due to snapshot checks, set --snapshots-update-policy=never in jf mvn-config during CI builds where snapshot consistency is guaranteed.
• Network bandwidth: Dependency resolution speed depends on the network path to Artifactory. Use a local or regional Artifactory instance for best performance.

Environment Variables

Downloading the Maven and Gradle Extractor JARs

For integration with Maven and Gradle, JFrog CLI uses build-info-extractor JAR files. These JARs are downloaded by JFrog CLI from JFrog's distribution (releases.jfrog.io) the first time they are needed.

Air-gapped or offline? See Air-Gapped and Offline Setup for a step-by-step guide.

Quick setup:

1. Create a remote Maven repository in Artifactory and name it extractors. Configure it to proxy https://releases.jfrog.io/artifactory/oss-release-local.
2. Verify that this Artifactory server is configured in JFrog CLI using jf c show.
3. Set the JFROG_CLI_EXTRACTORS_REMOTE environment variable. The value should be the Server ID followed by a slash and the repository name. For example: my-rt-server/extractors.
