steps

In sbt 1.10.5:

$ gh repo clone wvlet/wvlet
$ cd wvlet
# Edit project/build.properties to use sbt 1.10.5
$ ./sbt 
sbt:wvlet> runner/update
[success] Total time: 1 s, completed Dec 13, 2024, 11:08:53 AM

In sbt 1.10.6:

# Edit project/build.properties to use sbt 1.10.6
sbt:wvlet> runner/update
[success] Total time: 59 s, completed Dec 13, 2024, 11:12:14 AM
-- The second run still takes longer time than sbt 1.10.5
sbt:wvlet> runner/update
[success] Total time: 6 s, completed Dec 13, 2024, 11:13:36 AM

problem

Resolving some of the Java dependencies (Trino -> Apache Hadoop related dependencies?) in this build.sbt takes quite a long time. It was 1 second in sbt 1.10.5, but sbt 1.10.6 requires almost 1 minute:
https://github.com/wvlet/wvlet/blob/2987497fbc906149bb77c2a77d600b7f6270e2e9/build.sbt#L338-L355

Even after the first update run, there is still significant overhead.

expectation

As sbt update tasks always happen before recompilation, this step needs to be faster, at least after the first cold run.
