如何解决相同的Scala Task代码在沙盒中可用，但在intelliJ中不起作用
只需尝试一些简单的Task示例。以下代码可以正常工作
<!DOCTYPE html>
<html>
<head>
<style>
@keyframes sliding0 {
0% { left: 0; }
30% { left: 0; }
100% { left: -33vw; }
}
@keyframes sliding1 {
0% { left: 0; }
30% { left: 0; }
100% { left: -33vw; }
}
body {
background-repeat: no-repeat no-repeat;
background-size: cover;
background-position: center center;
}
div .glide_track {
position: relative;
width: 100vw;
overflow-x: hidden;
}
ul {
position:relative;
left: 0;
width: 330vw;
height:100vh;
animation-name: sliding0;
animation-duration: 3s;
animation-delay: 0s;
animation-iteration-count: 1;
animation-timing-function: linear;
margin: 0;
padding: 0;
list-style-type: none;
}
li {
position: relative;
left:0;
top:0;
float:left;
width: 32vw;
height:30vw;
display: inline-block;
margin: 0;
margin-right: 1vw;
padding: 0;
background-size: cover;
background-repeat: no-repeat no-repeat;
background-position: center center;
}
</style>
</head>
<body>
<script>
// we put the two lots of text and the image url for each slide in an array in the order they are to be shown
// this makes it easier to maintain when you want to add or remove a slide or change their order
// we only have one slider at the moment but this makes it more general
// these are the offsets in the array describing a slide. Done as indexes rather than named as easier to set up sliders array
const img = 0;
const text1 = 1;
const text2 = 2;
const sliders = [
[
['https://ahweb.org.uk/Boxfordmosaic.jpg','Shire','Valley<br> of Dreams'],['https://ahweb.org.uk/gear-in-turbine-house-reading.jpg','Westwood','Misty Woodlands'],['https://ahweb.org.uk/tricycle-in-abbey-ruins.jpg',['https://ahweb.org.uk/Boxfordmosaic.jpg','Valley<br> of Dreams']
]
];
// go through each slider and create its outer divs and its ul element
sliders.forEach(createSlider);
function createSlider(slider,sliderno) {
const div1 = document.createElement('DIV');
const div2 = document.createElement('DIV');
const ul = document.createElement('UL');
div1.classList.add("glide","hero-carousel");
div2.classList.add("glide_track");
div2.setAttribute("data-glide-el","track");
div1.appendChild(div2);
div2.appendChild(ul);
document.body.appendChild(div1);
ul.classList.add("glide__slides");
ul.addEventListener("animationend",animationEnd);
slider.forEach(createLi);
function createLi(slide,slideNo) {
const li = document.createElement('LI');
li.classList.add("glide__slide","carousel-item");
li.style.backgroundImage='url('+slide[img]+')';
li.addEventListener("click",slideClicked);
li.addEventListener("mouSEOver",slideHovered);
li.addEventListener("mouSEOut",slideUnhovered);
li.setAttribute('data-slideno','0' + slideNo);//! needs generalising if you have >10 slides !
ul.appendChild(li);
const div = document.createElement('DIV');
const p = document.createElement('P');
const h3 = document.createElement('H3');
p.innerHTML = slide[text1];
div.appendChild(p);
h3.innerHTML = slide[text2];
div.appendChild(h3);
li.appendChild(div);
}
}
// this is for testing,in real version use whatever required (i.e. whichever element is to have the hero image)
function ahHeroChange(backgroundImage) {
document.body.style.background = backgroundImage + " bottom/cover no-repeat";
}
function slideClicked(event) {
var slide = event.target;
var slideNo = slide.getAttribute('data-slideno');
// make the hero image the same as the slide's
ahHeroChange(slide.style.backgroundImage);
/* I don't kNow what these functions do - they were executed in the original on a click
number(slideno);
h4(slide.firstElementChild.querySelector('p').innerHTML);// text1 of the slide is passed to h4
h1(slide.firstElementChild.querySelector('h3').innerHTML;// text2 of the slide is passed to h1
*/
}
function slideHovered(event) {
var slide = event.target;
var slider = slide.parentElement;
slider.style.animationPlayState = 'paused';
ahHeroChange(slide.style.backgroundImage);
}
function slideUnhovered(event) {
var slide = event.target;
var slider = slide.parentElement;
//restore the hero image to the first one in the slider
ahHeroChange(slider.firstElementChild.style.backgroundImage);
//get the animation running again
slider.style.animationPlayState = 'running';
}
function animationEnd(event) {
//find the element that was clicked (it will be a ul element representing a slider)
var slider = event.target;
//take the first slide off the list and put it back at the end
slider.append(this.firstElementChild);
//change the hero image to the slide which is Now the leftmost - use modified heroChange in the final version
document.body.style.backgroundImage = this.firstElementChild.style.backgroundImage;
// toggle the animationName (to an identical keyframes action) to force the animation to start again
slider.style.animationName='sliding'+(Number(event.animationName.replace('sliding',''))+1)%2;
}
</script>

</html>但是使用runToFuture仅在沙箱中有效，而当我在intelliJ中运行它时不起作用（当然，在intelliJ中，我在对象内部运行它）
import monix.eval.Task
import monix.execution.CancelableFuture
import monix.execution.Scheduler.Implicits.global
import scala.util.Success
val task = Task { 1 + 1 }
val cancellable = task.runAsync {
case Right(result) => println(s"result is $result")
case Left(err) => System.out.println(s"ERROR: ${err.getMessage}")
}
无需打印2，只需
“ C：\ Program Files \ Java \ jdk1.8.0_192 \ bin \ java.exe”
可能是什么原因，我没想到这么早就卡住了。预先感谢
解决方法
作为独立程序运行时，该程序在任务完成之前退出，因此您不会获得任何输出。您需要等待任务完成。
Await.result(future,Duration.Inf)
