Usage

Running directly

Start by building the JAR using Gradle:

./gradlew build

Then, run the Java analyzer using build/libs/java-analyzer.jar. For example, to analyze a solution for the leap exercise, run:

java -jar build/libs/java-analyzer.jar leap /path/to/leap /path/to/output/folder

The analyzer output is written to analysis.json and tags.json in /path/to/output/folder.

Running with Docker

To run the Java analyzer using Docker, first build and tag the Docker image:

docker build -t exercism/java-analyzer .

Then, run the image and mount the directory of the solution to analyze. For example, to analyze a solution for the leap exercise located at ~/exercism/java/leap, run:

docker run -v /path/to/leap:/input -v /path/to/output/folder:/output exercism/java-analyzer leap /input /output

The analyzer output is written to analysis.json and tags.json in /path/to/output/folder.
