如何解决Intellij想法不将清单添加到工件的问题？

Question

I ran into a problem which I cannot solve neither by cleaning, nor by deleting Artifact/recreating it. I stuck with it for several days now and google search doesn't know such problem.

So, I have a Gradle java project in Intellij Idea, and it doesn't extract my manifest to Artifact's jar.

It does it in a different project, but here it doesn't include manifest, so my jar says no main manifest attribute, in txtadventureserver_main.jar

Here's the Artifact screen - manifest is not there and I don't see how I add it

here's my gradle:

group 'com.vladdrummer.txtadventureserver'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'idea'

sourceCompatibility = 1.8

jar {
    manifest {
        attributes 'Main-Class': 'TextAdventureServer'
    }
}
repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile "com.sparkjava:spark-core:2.7.2"
}

You can generate the MANIFEST.mf by going here in the Project Settings window:
