• What went wrong: Execution failed for task ':device_info_plus:compileDebugJavaWithJavac'.

• Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

For anyone experiencing this issue, the problem here was related to android studio being out of date.

Updated android studio and re-built my project and it works fine now.
