Make sure that the class com.jme3.system.JmeDesktopSystem exists in your classpath if you are trying to run jme from desktop.

Please, advise how I can do it

Your pasted Gradle build looks a little weird to me, unless I’m going crazy I think you have an odd number of braces in there, or a typo? Double check that’s accurate (or fix if you see the issue).

…To find classes in your classpath, IDEA should have some tree node in your project that you can expand to see what jars/classes are included.

How to type code blocks

Markdown code block : Embed your code in 3 backticks, like this ```<optional language> //your code here ``` If you don’t know how to type a backtick, here are some related links : How to type a backtick on windows For mac users : On qwerty keyboards it’s the key right to the left shift (along with the " key). On azerty keyboards it’s the key over the right shift (along with the £ key). This uses highlight.js, but uses a subset of the supported langages (following code block uses java)…

@ValeriiNikitin

plugins {
id ‘java’
}
apply plugin: ‘java-library’
group ‘org.contact.finewar’
version ‘1.0-SNAPSHOT’

Maybe its just a pasting outside a code block but when you look at these things ‘java-library’ they dont look like single quotes to me.

Anyway, assuming they are single quotes, I pasted in your gradle build into a netbeans 8 project, saved, reloaded the file and ran a BasicGame and had no problems.

Sounds like it may be an IDEA problem.

Fine works with such config:

plugins {
    id 'java'
}

group 'org.contact.finewar'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

jar {
    manifest {
        attributes "Main-Class": "mainpack.Test2"
    }

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

repositories {
    jcenter()
    mavenCentral()
}
def jme3 = [v:'3.2.4-stable', g:'org.jmonkeyengine']
dependencies {
    compile "${jme3.g}:jme3-core:${jme3.v}"
    compile "${jme3.g}:jme3-bullet:${jme3.v}"
    compile "${jme3.g}:jme3-networking:${jme3.v}"
    compile "${jme3.g}:jme3-desktop:${jme3.v}"
    compile "${jme3.g}:jme3-lwjgl:${jme3.v}"
    compile "${jme3.g}:jme3-plugins:${jme3.v}"
    compile "${jme3.g}:jme3-bullet-native:${jme3.v}"
    testCompile group: 'junit', name: 'junit', version: '4.12'
}
