Answer 1

You can get more details about the issue by setting a more detailed log level in application.properties, for example:

logging.level.dev.hilla=trace

But it seems that Maven cannot be found, and I see that the application you're trying to run misses the Maven Wrapper.

Either add the wrapper to the application or make sure your local Maven is available on PATH.
