classanalyzer's Introduction

ClassAnalyzer

Creates neo4j graph layout of classes and their relationships from a jar-application mapping

Sample usage:

Imagine you have microservices project which when compiled is composed of multiple jars. You want to analyze cross-application and other kinds of class relationships. Project is composed of subprojects A and B, which had compiled its jars into following folders:

  1. Project A:
  • /opt/projectA/lib1
  • /opt/projectA/lib2
  1. Project B:
  • /opt/projectB/libs

To analyze its relationships (in this project root folder) execute cmd:

./gradlew analyzeJars -PappMap="/opt/projectA/lib1,/opt/projectA/lib2=ProjectA;/opt/projectB/libs=ProjectB" \
-PclassInclude="com\..*|org\..*"  \ 
-PmethodInclude="com\..*|org\..*" \
-PdbFile="/home/user/project.graphb"

Script will generate class relationship data in /home/user/project.graphb
