Maven reverse dependency tree

Maven dependency mapper

• Example project and Screenshots

Stores dependency relationships in a graph database (neo4j). This maven plugin provides two operations:

# stores all dependencies in neo4j graph db
mvn dependency-mapper:store

# reads all reverse dependencies from neo4j graph db
mvn dependency-mapper:read

Local environment

• install neo4j http://www.neo4j.org/develop#install
• checkout this repo
• mvn install
• Go to a maven project and run mvn dependency-mapper:store
• To find out who is depending on your project do "mvn dependency-mapper:read"

Override neo4j server setting with -Dneo4jServer=http://yourserver:yourport, defaults to http://localhost:7474

Example output

mvn nodependency-mapper:read
