The Quickstart claims that the Java SDK supports Java version 8 or later but unfortunately the io.apimatic dependencies require 1.8 - at least as far as I can tell because I get unresolved dependency errors when trying to use Java 11. Is this a typo in the documentation or is there a way around this? Thxs.
Hmm, the team just went through the Quickstart with java version 17 and it worked. What dependency error are you getting? 
I assumed as much but can’t get past these errors when building with sbt 1.5.8 and java 11:

It actually looks like I misread and its maven dependencies rather than the apimatic dependencies. I should note I am using the newest release:
“com.squareup” % “square” % “26.0.0.20221116”,
Hey Bryan - forgive my ignorance as it appears that the root of the issue is that sbt is not able to expand the prerequisite maven version for the maven plugins - rather than a Java version issue. I misunderstood <required> in the pom file. However, still at a loss as to why.
Is the maven version your using the supported version?
I am not actually setting a maven version. I just get the dependency resolution error as soon as I add the square java sdk as a dependency to my project. It is possible that adding the project.prerequisites.maven variable to the square-java-sdk pom.xml would resolve the issue. I am trying to figure out how to set it in my project - as a workaround. What is the minimum maven version required for the square-java-sdk?
Looks like this issue logged on Github is somewhat related. Is anyone able to use the Java SDK with something other than Maven?
