The Java analyzer uses Abstract Syntax Trees (ASTs) to analyze submitted solutions using the javaparser library.

The documentation for this project can be found at exercism.github.io/java-analyzer/.

If you want to contribute to the Java analyzer, please refer to the Contributing Guide.

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.

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.

To run the unit tests:

./gradlew test

To run the smoke tests using Docker:
