+# Create an SBOM with reachable evidence
+
+## Learning Objective
+
+In this lesson, we will learn about generating an SBOM with reachable evidence for Dependency-Track, a Java application.
+
+## Pre-requisites
+
+Ensure the following tools are installed.
+
+```
+Java >= 17
+Maven
+Node.js > 18
+```
+
+## Getting started
+
+Install cdxgen
+
+```shell
+sudo npm install -g @cyclonedx/cdxgen
+```
+
+Clone and compile dependency track
+
+```shell
+git clone https://github.com/DependencyTrack/dependency-track
+cd dependency-track
+mvn clean compile -P clean-exclude-wars -P enhance -P embedded-jetty -DskipTests
+```
+
+Create SBOM with the research profile
+
+```shell
+cd dependency-track
+# Takes around 5 mins
+cdxgen -o bom.json -t java --profile research . -p
+```
+
+The resulting BOM file would include components with the occurrence and call stack evidence.
