Okapi Barcode is an open-source barcode generator written entirely in Java, supporting over 50 encoding standards, including all ISO standards. Okapi Barcode is based on Zint, an open-source barcode encoding library developed in C, and builds on the years of work that have been invested in that project.

gradlew check: Compiles and runs all quality checks, including the unit tests.
gradlew jar: Builds the JAR file.
gradlew uploadArchives: Deploys to Maven Central (requires a modified gradle.properties file).
NOTE: The unit tests should all pass under Oracle JDK, but will probably not all pass under OpenJDK. The tests verify barcode rendering image output, and the output images generated by OpenJDK are a bit different from the output images generated by the Oracle JDK (because their 2D graphics and font subsystems are slightly different).
