Cross-Platform Java Barcode SDK for Windows, Linux and macOS

This repository provides a simple example demonstrating how to build a cross-platform Java JAR package that encapsulates JNI shared libraries for Windows, Linux, and macOS, binding to the Dynamsoft C++ Barcode Reader SDK. For using production-ready Java barcode detection API, please download the official Java Barcode SDK directly.

License Key for Dynamsoft Barcode Reader SDK

Obtain a 30-day free trial license.

JNI Header Generation

Navigate to your Java source directory and generate the JNI header file:

cd src/main/java
javah -o ../../../jni/NativeBarcodeReader.h com.dynamsoft.barcode.NativeBarcodeReader

Build the JNI Shared Library with CMake

Windows

mkdir build
cd build
cmake -DCMAKE_GENERATOR_PLATFORM=x64 ..
cmake --build . --config Release --target install

Linux & macOS

mkdir build
cd build
cmake .. 
cmake --build . --config Release --target install

Build the JAR Package Using Maven

mvn package

Test the JAR Package for Barcode Reading

1. Set the license key in Test.java:

   barcodeReader.setLicense("LICENSE-KEY");

2. Run the test:

   java -cp target/barcode-1.0.0.jar Test.java <image file>
