This is taken from build.gradle.kts

tasks{   
 "bootJar"(BootJar::class) {
        archiveFileName.set("imps.jar")
    }}

I was wondering what kind of language construct allows me to write string followed by (). I mean "bootJar"(BootJar::class). What is that? -- I found that string boot initializer uses

withType<Test> {
        useJUnitPlatform()
    }

What is the preferred way to modify tasks?

String.invoke()

is declared on

DependencyHandlerScope

Here is some documentation regarding configuring tasks: https://docs.gradle.org/current/userguide/task_configuration_avoidance.html

err, that's for tasks, so TaskScope or something

Ok, so its invoke operator overload. Thank u both.
