Unable to provision. Caused by: java.lang.NumberFormatException: For input string: "port"

### Affected version

1.0.3

### Bug description

Can anyone please point me where to start - I have a large code base and one of the modules just started reporting this on build. Other poms seem fine. I don't even know where to start

**Update while writing this report** Changing `.mvn/maven-build-cache-config.xml` `$/configuration/remote@enabled=false` seemed to make the error stop and still use the mvnd. Keeping for comment.

```

Start with .mvn/maven-build-cache-config.xml and the RemoteCacheRepositoryImpl constructor at line 80, using the reported mvnd build and log to reproduce the failure. Compare behavior with remote caching enabled and disabled, then trace why the value "port" is parsed as a number. Done means the reported configuration no longer causes the NumberFormatException during provisioning.
