java.lang.RuntimeException：运行 `uname` 命令时出错

Question

我正在按照 this 在我的 Java 程序中使用 pdal。 我在我的 pom 中添加了以下依赖项：

<dependency>
    <groupId>io.pdal</groupId>
    <artifactId>pdal-native</artifactId>
    <version>2.7.0</version>
</dependency>

<dependency>
    <groupId>io.pdal</groupId>
    <artifactId>pdal_3</artifactId>
    <version>2.7.0</version>
</dependency>

<dependency>
    <groupId>io.pdal</groupId>
    <artifactId>pdal-scala_2.13</artifactId>
    <version>2.7.0</version>
</dependency>

代码是：

Pipeline pipeline = new Pipeline(json, LogLevel.Info()); //error on this line
pipeline.execute();

但这失败了：

java.lang.RuntimeException：运行

uname

命令时出错

我不确定“uname”的来源。它不是我的管道 json 的一部分。

我错过了什么？

编辑：

这是堆栈跟踪：

总结评论：您正在使用的库对于您运行程序的操作系统不可行。

uname

是一个存在于 Unix 上的程序（因此也存在于 Linux 和 MacOS 上），但不存在于 Windows 上。

因此在 Windows 上运行您的程序预计会失败。
