TPekko SBT build is currently configured to detect Java 8 installation via the JAVA_8_HOME environment variable (see https://github.com/apache/incubator-pekko/blob/85c2a469098abd064738dbf9bb50f3cc271dc73b/project/JdkOptions.scala#L94 ). The reason why the ubuntu docker images/github actions CI can build Pekko without any additional JDK configuration/work is that the ubuntu image is already preinstalled with various JDK's installed with the relevant JAVA_<VERSION>_HOME environment variables exposed.
