Read all poms in a directory and output a dependency graph

Pom Graph

This Java tool recursively searches a directory for Maven POM files and builds a dependency graph. The tool can write either a adjacency list style CSV (which can be read by at least Gephi) or a GraphML file (which can be read by most graph analysis tools).

Prerequisites

• A Java 8 development kit
• A copy of Maven installed and on the Path environment variable

Compiling and running

Clone this repository or download a zip. To compile, run mvn package in the directory you just cloned or downloaded. To run, run java -jar target/pom-graph-1.0-SNAPSHOT.jar or on Windows, simply double clicking the jar file in the target directory should work as well.

Usage

-d,--directory Directory that will be scanned recursively for POM files, required

-f,--format Output format, can be "csv" (adjacency list) or "graphml", required

-h,--help Prints this message

-i,--include-version Whether to create a separate node for each version of an artifact, or merge them all into one node

-o,--output Output file, required

Known issues

• The tool does not fully resolve POM files, so artifact IDs, group IDs and version numbers can appear in the graph in an unresolved form. Fully resolving has a large overhead but might be investigated in the future.
