[ENHANCEMENT] mvnd failed while I purposely disabled ~/.m2 directory

[yiding-he]

I purposely disabled read/write access to ~/.m2 directory and set <localRepository> to other location to prevent any downloading of jars to my home directory. Maven works fine but mvnd fails:

Exception in thread "main" org.mvndaemon.mvnd.common.DaemonException: java.nio.file.AccessDeniedException: C:\Users\yidin\.m2\mvnd
        at org.mvndaemon.mvnd.common.DaemonRegistry.<init>(DaemonRegistry.java:79)
        at org.mvndaemon.mvnd.client.DefaultClient.execute(DefaultClient.java:171)
        at org.mvndaemon.mvnd.client.DefaultClient.main(DefaultClient.java:98)
Caused by: java.nio.file.AccessDeniedException: C:\Users\yidin\.m2\mvnd

        at org.mvndaemon.mvnd.common.DaemonRegistry.<init>(DaemonRegistry.java:72)
        ... 2 more

So I think what I need is for mvnd to ignore this failure and print a warning message instead.

Failure to create the DaemonRegistry cannot be ignored because it is vital for the daemon. You can pass an alternative registry location via -Dmvnd.daemonStorage=/some/writable/path on the command line or by adding mvnd.daemonStorage=/some/writable/path to ~/.m2/mvnd.properties. Does that help?

Seems it works, thanks!
