GBFS Validator Java Example

A minimal example project demonstrating how to use the gbfs-validator-java library to validate GBFS feeds programmatically.

What it does

• Fetches a public GBFS feed (BIXI Montreal by default)
• Validates a single file using GbfsValidator.validateFile()
• Validates a full multi-file feed using GbfsValidator.validate()
• Prints validation results including errors, version, and schema info

Prerequisites

• Java 17+
• Maven 3.6+

Running

mvn compile exec:java -Dexec.mainClass=org.mobilitydata.gbfs.validator.example.GbfsValidatorExample

Using a different GBFS feed

Edit the GBFS_FEED_URL constant in GbfsValidatorExample.java to point to any public GBFS feed.

Using a release version

To use a stable release instead of a snapshot, change gbfs-validator.version in pom.xml to a published release version, e.g. 3.0.1, and remove the snapshot repository configuration.
