build gradle project in Intellij with local libraries

Question

I need to generate a jar file of my project. This is my first time using gradle.

Inside intellij, i'm executing "gradle -> Tasks -> jar" to generate the jar file. The jar file is generated inside "build -> libs", opening the prompt inside the directory, i can execute the command:

java -jar .\gradle-project.jar (I ensured that the version of java executed at the prompt is the same as that configured in intellij)

But console prints:

java.lang.UnsatisfiedLinkError: no SimpleITKJava in java.library.path

I know what this error is, this error occurs when java can't find one of the gradle library called SimpleITK, there is no online repository for this library, so I downloaded the library and configured gradle to use the local files. In my run / debug configuration, i put this in VM options:

-Djava.library.path="D:\path-to-gradle-project\libs\SimpleITK-2.3.0"

this VM options fix the error, so it should fix for prompt too right?

Then, when i try:

java -Djava.library.path="D:\path-to-gradle-project\libs\SimpleITK-2.3.0" -jar .\gradle-project.jar

console prints:

Error: Could not find or load main class .library.path=D:\path-to-gradle-project\libs\SimpleITK-2.3.0
Caused by: java.lang.ClassNotFoundException: /library/path=D:\path-to-gradle-project\libs\SimpleITK-2/3/0

What is wrong? Thanks for reading this far! This is my build.gradle file:

plugins {
    id 'java'
    id 'application'

}

    implementation("org.openjfx:javafx-base:20.0.2")

}

test {
    useJUnitPlatform()
}

jar {
    manifest {
        attributes 'Main-Class' : 'com.webkriativa.noahviewer.Main'
    }

    duplicatesStrategy = 'exclude'

    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }

}

I solve this problem like this: java -D"java.library.path"="D:\my-project-path\libs\SimpleITK-2.3.0" -jar .\build\libs\my-project.jar
