Duplicate of this issue

SourceSetOutput.getClassesDir() was deprecated in Gradle 4 and removed in Gradle 5. Please use getClassesDirs() in Gradle 5

In your instance, the problem is with 

sourceSets.main.output.classesDir

Change it to

sourceSets.main.output.classesDirs

Also, you can omit most of the files(...) calls in your task definition as most of the Jar tasks methods accept Object. Eg:

task dist(type: Jar) {
    from sourceSets.main.output.classesDirs
    from sourceSets.main.output.resourcesDir
    from {configurations.compile.collect {zipTree(it)}}
    from project.assetsDir

    manifest {
        attributes 'Main-Class': project.mainClassName
    }
}
