Gradle, 'url' cannot be applied to (java.lang.String)

Question

Since some time, on any maven { url "whatever" } I'm getting this warning:

Here a sample project experiencing the issue

It's not critical neither a blocker, but it's kind of annoying

Does anybody know where it comes from?

Specs:

• Idea IU 181.3263.15
• JRE 1.8.0_152
• kotlin 1.2.21
• gradle 4.4.1
• Win 7 x64

Answer 1

To make IntelliJ IDEA stop complaining, you can use:

maven {
    url = 'http://myrepo'
}

which I believe is the Groovy shortcut for setUrl('http://myrepo').

Answer 2

Your IDE is analyzing the Gradle DSL. With fully expanded syntax, your code looks like this:

project.dependencies({(RepositoryHandler handler) -> {
   handler.maven({(MavenArtifactRepository repository) -> {
       repository.setUrl("https://...");
   });
};

If you look in the Gradle API, you can see that MavenArtifactRepository has two methods:

void    setUrl(Object url)
void    setUrl(URI url)

So the IDE is saying you should pass Object or an URI. If you use setUri(...) the annoying IDE warning should go away.
