What’s the Kotlin equivalent of the Groovy List<T>.join(..) function?

[nanodeath]

joinToString?

[zak.taccardi]

so the function I’m actually converting is:

android.bootClasspath.join(File.pathSeparator)

android.bootClasspath: List<File>
File.pathSeparator: String

but I think it will do the trick! thanks!

[zak.taccardi]

task.classpath += objects.fileCollection()
  .from(android.bootClasspath.joinToString(File.pathSeparator))

Do you actually want to combine strings

[Nir]

or are you concatenating paths?

[zak.taccardi]

I have no idea lol

Basically, trying to convert the following into Kotlin

TaskProvider<Javadoc> javadocs = tasks.register(javadocsTaskName, Javadoc) {
        excludes = ['**/*.kt']
        source = android.sourceSets.main.java.source
        classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
    }

[zak.taccardi]

and what I have is:

val javadocs = tasks.register(javadocsTaskName, Javadoc::class.java) { task ->
    task.setExcludes(listOf("**/*.kt"))
    val mainSource = android.sourceSets.named("main")
        .map { main -> main.java.sourceFiles }
    task.source = mainSource.get()
    task.classpath += objects.fileCollection()
        .from(android.bootClasspath.joinToString(File.pathSeparator))
}

[nanodeath]

.joinToString(File.pathSeparator)

is almost definitely concatenating paths 😛 but is also a fine way to do it. You could do some kind of Paths.get(*android.bootClasspath).toString() thing probably, but eh
