Question

我正在尝试使用javacpp-presets二进制文件从Java访问librealsense库。我该如何使用它们？在github页面上，它表示除了javacpp.jar之外，在我的类路径中的某个位置放置所有所需的JAR文件（opencv * .jar，ffmpeg * .jar等）就足够了。

我使用以下结果运行以下命令：

$ javac -cp javacpp-presets-bin/javacpp.jar:javacpp-presets-bin/librealsense.jar TestConnection.java
$ java -jar javacpp-presets-bin/javacpp.jar TestConnection
Warning: Could not load platform properties for class TestConnection
$ java -cp javacpp-presets-bin/javacpp.jar:javacpp-presets-bin/librealsense.jar:. TestConnection

感谢任何帮助。

我应该使用librealsense-platform.jar

$ javac -cp javacpp-presets-bin/javacpp.jar:javacpp-presets-bin/librealsense-platform.jar TestConnection.java
$ java -jar javacpp-presets-bin/javacpp.jar TestConnection
$ java -cp javacpp-presets-bin/javacpp.jar:javacpp-presets-bin/librealsense-platform.jar:. TestConnection

如何使用Javacpp预设二进制文件
