A modern programming language that makes developers happier.

kotlinlang

I am reading a book on Gradle, little bit old from 2012 or something like that. There is a `&lt;&lt;` syntax I encountered which is an alternative of `doLast` . Here is a snippet,

```3.times {
 task "yayGradle$it" &lt;&lt; { 
 println 'Gradle rocks'
 }
}```
but it isn't working. I anticipate the syntax my have been deprecated. Can anyone point out which version I can use to run that snippet?

it has autocomplete and control B works :)

I will use Kotlin but I want to follow the snippets of the book

task.register(name) {
    doLast { … }
}

&lt;&lt; syntax is discuraged even for Groovy.
It's eager API (so it works not exactly the same as suggested "register")

I wouldn't probably spent time on such an old book, it will not help with modern best practices, 9 years is a huge time, especially for software which releases new version every month, and instead would start from official guides

<@U0BRK9HC5> Yep, now I am doing that. Actually, I needed some background in Gradle. I tried first with a hands-on tutorial. Still the same overwhelmed feeling. Later on I found that page. It's the "Authoring Gradle build" section.

Gradle is probably the most "less-demystified" technology that I have ever come across. Almost no helpful tutorial on Youtube. And most of the articles are providing some kind of "hands-on". Nobody is talking about the fundamentals. So, yeah documentation is the safest bet here.

<@U0BRK9HC5> <@UE206C71V> thanks both of you :upside_down_face:

There is just an incredible amount of good tutorials about Gradle

It really depends on what you are looking for

Then I have surely missed something obvious. Can you share one? That would guide me piece by piece? I don't want something that would just spit out hundreds and thousands of files once I run `./gradlew build` . I want something that talks about more fundamentals. So that I can understand what's going on.

From recent videos I would highly recommend this series, it covers some core concepts of Gradle

Effectively, I can do two things,

1.

```kotlinc -cp someJar someKtFile
java -cp someJar someClassFile```
2.

```a. Initialise a Gradle project using Intellij

b. write some code (maybe add some `implementation` in between in the build.gradle file)

c. and run that using some IDE features```
I want something that would bridge the gap between these two.

Hmm... that playlist seems promising. Let's give it a go.

The leftshift syntactic sugar was deprecated in 3.2 and removed in 5.0.
So if you really want to use such old snippets, you need to use a Gradle version &lt;5.0.
But I agree that a tutorial for that old versions is maybe not too helpful. :smile:

On the other hand, if you do go with learning Gradle 2 then you’ll be amazed when you see what each next major brings :wink:
