won't compile, I got this instead Error:java: javacTask: source release 1.8 requires target release 1.8

My guess is that the bytecode target is set somewhere else in the video. I did this before I tried the "sourceCompatibility = 1.8" solution and it worked too. It is in File > Settings > Build, Execution, Deployment > Compiler > Java compiler , you will see below the per - module there is/are modules, you select one and to the right of that are your options.. I don't know why it defaults to 1.5. I'm testing the Project bytecode option as I write this.

you just need to change sourceCompatibility to proper sdk version in your build.gradle file

I've a new question. Its about the 'maven repository' being 'unindexed' popup message. I'm thinking about clicking Disable... I clicked the update repository first but it takes a long time. It still pops up, the message. I'm using IntelliJ 2016.1.

my soursecCompatibility = 1.5 is underlined in gray and the lightbulb says "Argument is not used". anyone know how to fix this? im also having the issue "won't compile, I got this instead Error:java: javacTask: source release 1.8 requires target release 1.8"

Hi, everyone

Just wanted to mention that it seems exist another solution to this problem, provided by Michael Walters here

Quoting his answer

The error is: Error:java: javacTask: source release 1.8 requires target release 1.8

When you leave 'Create separate module per source set' checked, if you open Preferences > Build, Execution, Deployment > Compiler > Java Compiler, the version per module is set to 1.6 or lower. That causes the error.

But, if you don't check it, IntelliJ doesn't set versions per module, and the release error doesn't happen.

It is similar for solution of Albert Evangelista , but using the way above it looks like one does not even need to go to

Preferences > Build, Execution, Deployment > Compiler > Java Compiler

line, to change anything

this is what is on the build.gradle

group 'com.teamtreehouse.courses' version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.5

repositories { mavenCentral() }

dependencies { compile 'com.sparkjava:spark-core:2.3' testCompile group: 'junit', name: 'junit', version: '4.11' }

this is in Main.java

package com.teamtreehouse.courses;

import static spark.Spark.get;

public class Main { public static void main(String[] args) { get("/hello", (req, res) -> "Hello World"); } }
