Gradle download sources failed

Question

I'm using Gradle build tool and I can't get the source code and docs for spark-core. I've already searched and applied:

idea {
    project {
        jdkName = '1.8'
        languageLevel = '1.8'
    }
    module {
        downloadJavadoc = true
        downloadSources = true
    }
}

But it still doesn't work for me. I suppose I'm missing something like rebuild the whole project or download just these pieces.

I applied ./gradlew cleanIdea idea as well.

When I try to click with pressed command on SparkConf.class I press Download Sources I get Sources not found for: org.apache.spark:spark-core_2.12:2.4.5

And the result from the run tab:

21:11:29: Executing task 'DownloadSources'...

:DownloadSources FAILED

BUILD FAILED

Total time: 0.124 secs

FAILURE: Build failed with an exception.

* Where:
Initialization script '/private/var/folders/06/97bzw1l51r59l65thfzs7hd80000gn/T/ijmiscinit1.gradle' line: 14

* What went wrong:
Execution failed for task ':DownloadSources'.

Here is 2 pretty long task outputs:

Could you please help me to realize what should I do to fix it?

did you try adding the sources classifier in the build.gradle? — Sai Kiran KrishnaMurthy, May 31 '20 at 18:46
`compile group: 'org.apache.spark', name: 'spark-core_2.12', version: '2.4.3',classifier:'sources'` this works fine for me — Sai Kiran KrishnaMurthy, May 31 '20 at 18:49
@SaiKiranKrishnaMurthy thank you for the thought. Should I run build after this or should it work instantly? — iamtodor, May 31 '20 at 18:54
After I add this I did `invalidate and restart` from File and `clean rebuild` gradle task, but still can't reach the docs — iamtodor, May 31 '20 at 18:59
invalidate doesnt help you, you need to refresh the gradle project so it can refresh the depedencies — Sai Kiran KrishnaMurthy, May 31 '20 at 19:01
in the gradle tool window, you should have a "reimport all projects" icon (like a circle) — Sai Kiran KrishnaMurthy, May 31 '20 at 19:03

I did `Refresh Gradle Dependencies` from https://stackoverflow.com/a/47557700/5151861 still can't reach the docs and get failed while trying to download it — iamtodor, May 31 '20 at 19:06
@SaiKiranKrishnaMurthy `reimport project` tried as well, still nothing :( — iamtodor, May 31 '20 at 19:06
in the external libraries, do you see `spark-core_2.12-2.4.5-sources.jar` ? — Sai Kiran KrishnaMurthy, May 31 '20 at 19:09
@SaiKiranKrishnaMurthy from what I see I don't have it: https://imgur.com/a/T2pQ8x7 — iamtodor, May 31 '20 at 19:20
this is why you dont see the sources, if after you did a reimport it didnt change then something is wrong with your intellij/gradle setup. I would look into this https://www.jetbrains.com/help/idea/gradle.html — Sai Kiran KrishnaMurthy, May 31 '20 at 19:35
I tried to make this happen in the new project: `./gradlew build --warning-mode=all` > Configure project : The compile configuration has been deprecated for dependency declaration. This will fail with an error in Gradle 7.0. Please use the implementation configuration instead. at build_ch9eewobhc2rtmdi9qkyp7xzn$_run_closure3.doCall(/Users/iamtodor/data_engineer/code/test_gradle/build.gradle:22) (Run with --stacktrace to get the full stack trace of this deprecation warning.) — iamtodor, Jun 01 '20 at 05:41
Maybe you are running from behind corporate proxy and idea does not have it set up? — charlie_pl, Jun 01 '20 at 08:00
@charlie_pl nope, I do not have any proxy or VPN. I can reach https://repo.maven.apache.org/maven2/ from my browser — iamtodor, Jun 01 '20 at 08:18
@SaiKiranKrishnaMurthy the problem lays in Scala plugin, I had no installed Scala plugin before. — iamtodor, Jun 01 '20 at 15:31

The problem belongs to Scala plugin. If you face this issue, it doesn't matter on build tool you are using Maven or Gradle probably installation of the Scala plugin solves your problem.
