how to add dependency to current active project in intellij plugin programatically

You can download file using i.e.

final DownloadableFileService downloader = DownloadableFileService.getInstance();
final DownloadableFileDescription description = downloader.createFileDescription(jarUrl, jarName);

DownloadableFileService.getInstance().createDownloader(description).download(targetDir);

Hi Jakub Chrzanowski,

Thanks, But I want to clarify that the jars are nothing but external libraries like gson, Jsch, opencsv. So what will be the targetDir to store these jars on a current active project .

It depends on your project's configuration and flows, I'm not aware of your project type nor use case, unfortunately.

ModuleRootModificationUtil may help you with setting a module directory programmatically.

Thanks Jakub, It can be any project like maven or gradle or can be a new Platform plugin. So, I need irrespective of the project that download should happen to correct destination. If it is a maven project i can handle the code of adding dependency section to pom.xml. But I am not aware the code to  where or how to download that dependency to the current active project

As above - I've provided you with the way for east downloading the jar file and the method to add libraries to the given module. You just to have to connect these pieces into a solution.

Working with the Maven or Gradle dependencies is more complex and requires from you digging deeper in the related code, which you may find in the intellij-community repository.

Thanks  Jakub, I will check into it.
