I have an app that runs fine in cmdline but when run in Eclipse fails with the stracktrace:\r\n\r\nException in thread \"main\" java.lang.ExceptionInInitializerError\r\n...\r\nCaused by: org.usb4java.LoaderException: Native library not found in classpath: /org/usb4java/win32-x86-64/libusb4java.dll\r\n\tat usb4java@1.3.0/org.usb4java.Loader.extractLibrary(Loader.java:246)\r\n\tat usb4java@1.3.0/org.usb4java.Loader.load(Loader.java:323)\r\n\tat usb4java@1.3.0/org.usb4java.LibUsb.\u003cclinit\u003e(LibUsb.java:690)\r\n\t... 6 more\r\n\r\nI can't see how to resolve this if I want to use the native libs directly because we have to call LibUsb.init() - the library demands it. But in doing so it ends up in Loader.load() and then Loader.extractLibrary() where the LoaderException is thrown because it can't resolve the path.\r\n\r\nSo, how does one realise this statement without a switch for bypassing this attempt to load a native?:\r\n\r\n\"usb4java only extracts the files into a temporary directory when they are inside a JAR file.\"\r\n","author":{"url":"https://github.com/gmseed","@type":"Person","name":"gmseed"},"datePublished":"2023-10-11T15:51:13.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/88/usb4java/issues/88"}
