Can't run the Hello World!-example, build fails with cannot find dolast() for arguments

Running the first hello world example in the online installation tutorial ( the build fails with “Could not find method dolast() for arguments [build_3j5djcu6u9fre9vqmqpvdsbt4c$_run_closure1_closure2@3219ab8d] on root project”

Any clues would be grateful!

thanks in advance,


task hello {
  println "Hello World!"

The method name of doLast has a capital letter “L”. You lower-cased the method name.

task hello {
    doLast {
        println "Hello World!"

Debug log found here

I just posted the solution above.


However, the example still does not succeed when using the command in the doc:

gradle -q hello:

Project ‘hello’ not found in root project ‘projname’

When I do gradle -q hello

it works fine?!

If you are referring to the ‘hello’ task in the root project which you do in your case, the colon character (:slight_smile: has to come first. You have to call it like this: ‘gradle -q :hello’.

In the sentence of the user guide, the colon is actually not part of the command.
