这是我在 Arduino Uno 板上闪烁 LED 的代码，但它会抛出

Load RxTx
java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path

    at NClang.tinycompile.Blink.main(Blink.java:36)

我已将 rxtxSerial 库导入我的路径，当我尝试再次导入它时，它说：

rxtxSerial already in path, no changes have been made

我在这个网站上看过一些关于这个问题的帖子，但他们都说“将 rxtxSerailcomm.jar 和 .dll 导入正确的目录。我遵循了这个建议，但仍然得到完全相同的错误

您必须确保将库（dll/so文件）添加到您的项目中。Native library location你必须在你的设置中寻找。看看下面。

在此处输入图像描述

你想在那里添加你的dll/so文件。

您需要添加org.sintef.jarduino.core-0.1.7-SNAPSHOT.jar到您的构建路径（右键单击您的项目 -> Build Path-> Configure Build Path->Libraries选项卡）
