FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':fancyshowcaseview:compileDebugKotlin'.

'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.
Consider using JVM toolchain: https://kotl.in/gradle/jvm/toolchain

Fixed in da2981a. Added compileOptions and kotlinOptions to both library and app modules to ensure Java and Kotlin compile to the same JVM target (1.8).
