- Java 11 (For usage as a standalone tool)
- Docker (For usage as a container)
usage: ./codeanalyzer [-h] [-i <arg>] [-e <arg>] [-o <arg>] [-q]
Convert java binary (*.jar, *.ear, *.war) to its equivalent system
dependency graph.
-h,--help Print this help message.
-i,--input <arg> Path to the input jar(s). For multiple JARs,
separate them with ':'. E.g.,
file1.jar:file2.jar, etc.
-e,--extra-libs <arg> Path to the extra libraries to consider when
processing jar(s). This arg will the the path the
to directory.
-o,--output <arg> Destination (directory) to save the output
graphs.
-q,--quiet Don't print logs to console.There are some sample binaries in github.com/rahlk/dgi-sample-applications. As an example usage, we'll use daytrader8 as shown below:

This will produce a JSON file called sdg.json at /path/to/dgi-sample-applications/daytrader8/output.
A containerized version of code-analyzer is available at quay.io/rkrsn/code-analyzer. As an example usage, we'll again use daytrader8 as shown below:
docker run --rm \

-v /path/to/dgi-sample-applications/daytrader8/daytrader8/libs/:/dependencies \
