java.lang.RuntimeException: Error running `uname` command

Question

I am following this to use pdal in my Java program. I have added following dependencies in my pom:

<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>

Code is:

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

But this fails with:

java.lang.RuntimeException: Error running uname command

I am not sure of origin of 'uname'. It's not part of my pipeline json.

What am I missing?

Edit:

Here is the stacktrace:

Answer 1

To summarize the comments: the library that you are using is not feasible for the operating system you run the program on.

uname is a program that exists on Unix (therefore also on Linux and MacOS), but not on Windows.

So running your program on Windows is expected to fail.
