To get the reason you need to refer to CommandInvocationFailure in Build failed logs

CommandInvocationFailure in unity console

#1 Error: uses-sdk:minSdkVersion 'x' cannot be smaller than version 28 declared in library

JMRSDK has a dependency on SDK version 28 and hence build will fail when the minimum API version specified in project settings will be smaller than version 28.

Fix: Make sure that the minimum API level is set to 28 and the target API level is set to 34.

#2 Error: Could not get unknown property 'vstsMavenAccessToken' for Credentials [username: tesseractimg].

There are dependencies of the Gradle properties template on the base Gradle template.

Fix: Make sure to select all the publishing build settings correctly as shown in the image below.

#3 Error: Keystore passwords incorrect

Project Keystore incorrect

Project Key password was incorrect
