## Overview


FOSSA supports Clojure projects built with [Leiningen](https://leiningen.org/), the most common Clojure package manager. Clojure analysis is performed with the **FOSSA CLI**.

## Tool support

| Tool | Quick Import (app.fossa.com) | CLI (fossa-cli) |
| :-- | :-- | :-- |
| Clojure (Leiningen) | N/A | `project.clj` |

## Analyzing with the CLI

Clojure dependencies are specified in a `project.clj` manifest, which the `lein` tool uses to build a dependency graph and download the correct dependencies.

Install the latest release of `fossa-cli`:

```shell
curl -H 'Cache-Control: no-cache' https://raw.githubusercontent.com/fossas/fossa-cli/master/install-latest.sh | bash
```

Then run `fossa analyze` from your repository's root directory to analyze your Clojure project using Leiningen. See the [Leiningen strategy reference](/docs/project-setup/supported-languages/clojure/leiningen) for detection and analysis details.

Step-by-step onboarding paths for developers, security teams, and legal & compliance.

Install the CLI, analyze your first project, and wire FOSSA into CI so every pull request is checked automatically — no manual scans.

For Developers

Detect CVEs across your dependencies, set severity policies that gate builds, and focus on vulnerabilities that are actually reachable in your code.

For Security Teams

Surface license obligations per dependency, enforce policies that flag or block disallowed licenses, and produce audit-ready attribution reports automatically.

For Legal & Compliance

New to FOSSA? Import your first project, run a scan, and see results in minutes.

Create an account, import your first project, read the results, and automate future scans.

Your First Scan

Choose between Quick Import and the FOSSA CLI based on your build environment and accuracy needs.

CLI vs Quick Import

Get Started

Get your code into FOSSA — import projects from source hosts, the CLI, or CI, then configure how they're scanned and organized.

Analyze your code locally with the FOSSA CLI and upload the results, the most accurate and secure way to integrate.

Provide dependency data from your existing CI/CD environment for faster, more accurate FOSSA scans.

CI/CD Scanning

Block PRs that introduce new license compliance or security violations using FOSSA GitHub status checks.

Pull Request Checks

Automatically add a FOSSA license-scan status badge to your GitHub README when you import a project.

Badge Pull Requests

Scan Docker and OCI container images for open source license and vulnerability issues.

Containers

Find open source code copied into your codebase without being declared as a dependency.

Snippets

Connect GitHub, GitLab, Bitbucket, or Azure Repos and scan hundreds of repositories in one click.

Quick Import

Import internal and firewalled projects into FOSSA with Broker, without sharing source-code access.

Broker

Decompose pre-compiled binaries and archives to identify open source components without source-code access.

Binaries

Import a CycloneDX or SPDX SBOM to run license and security compliance checks against its listed components.

SBOM Import

Inspect every dependency FOSSA detected, metadata, license status, filter options, custom licenses, and notice files.

Dependencies

Search, filter, and manage every package detected across all of your organization's projects from one place.

Package Inventory

Configure the title, branches, ignored dependencies, labels, VCS host, and visibility for an individual FOSSA project.

Project Settings

Exclude a specific package from your project's issue tracking and reporting.

Ignore a Dependency

Create and apply labels to organize projects and filter the dashboard by business context.

Project Labels

Keep FOSSA projects continuously scanned, re-analyze on every new revision and surface new license and security issues automatically.
