我正在研究studens項目，它需要讀取通過USB從AtMega發送的數據（使用虛擬串行端口）。要訪問串口，我使用的是NeuronRobotics的nrjavaserial（https://github.com/NeuronRobotics/nrjavaserial），這是RXTX的一個分支。爲了管理我的依賴，我使用了maven。下面是我得到的，當我運行CommPortIdentifier.getPortIdentifiers();（或任何靜態CommPortIdentifier功能）：java.lang.UnsatisfiedLinkError：在調試期間只能找到依賴庫

Strangly，這只是在調試過程中發生的，當我運行程序通常它的工作原理像魅力。任何想法爲什麼？
我發現人們與其他庫有類似的問題，但所有這些解決方案是移動DLL或更新類路徑，但正如我使用的Maven我懷疑在這種情況下，解決方案將有所不同。
