Unable to build with shadow

Im trying to build my mod using shade since i use the luaj library however i keep getting this error

Reason: Task ':reobfJar' uses this output of task ':shadowJar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.

So i try adding

reobfJar.dependsOn shadowJar

 Could not get unknown property 'reobfJar' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

my gradle file

plugins {
    id 'eclipse'
    id 'idea'
    id 'maven-publish'
    id 'net.minecraftforge.gradle' version '[6.0,6.2)'
    id 'com.github.johnrengelman.shadow' version '7.1.2'
    id 'org.spongepowered.mixin' version '0.7.+'
}
apply plugin: 'net.minecraftforge.gradle'
