this is a mix of a spring/gradle question. with the spring boot gradle plugin, is there anyway to copy the runnable jar to a different location and rename it? I've tried to do it with just a copy task, but that's messy because it depends on the project name. I'd rather just copy the single runnable jar without regex.

You can use a task as an input to a copy task - it'll work out the task dependency and input file for you

You could also change the output filename for the runnable jar task

I think there are several output files though, like sources and javadoc. I only want the runnable

The `BootJar` task extends the standard `Jar` task

from ```val copyBoot = tasks.create&lt;Copy&gt;("copyBootJar") {
    from("build/libs") {

        exclude("*-javadoc.jar")

    exclude("**/*.bak")
    rename(".*.jar", "runnable.jar")
    includeEmptyDirs = false
}
copyBoot.dependsOn("bootJar")
tasks["assemble"].dependsOn(copyBoot)```

to ```
        val copyBoot = tasks.create("copyBootJar", Copy::class.java) {
            from(tasks["bootJar"])
            into("build/runnable")
            rename(".*.jar", "runnable.jar")
        }
        copyBoot.dependsOn("bootJar")
        tasks["assemble"].dependsOn(copyBoot)
```
