how to get userid and gid in gradle?

Question

I can do this in the build.gradle:

println System.getProperty("user.name")

How do I get user ID and primary group ID for current user in a Linux machine?

Capturing the output of exec is the last thing I want to do.

Gradle doesn't provide such functionality out-of-the-box, however running commands in groovy is fairly easy. Below sample gradle script that does the job:

def username = System.properties['user.name']
println "Username $username"
def uid = ["id", "-u", username].execute().text.trim()
println "UID: $uid"
def gid = ["id", "-g", username].execute().text.trim()
println "GID: $gid"

To get the id of current user, just omit the username altogether. – Jan Hudec Dec 16 '21 at 21:44

There is an api for this kind of thing actually

def uid = new com.sun.security.auth.module.UnixSystem().getUid()

How to do it on Windows? I have no idea
