@gnodet Any chance of some feedback on this? It is preventing us from using mvnd.

Same here - if I manually increase the timeout in DaemonConnector.CONNECT_TIMEOUT and rebuild mvnd then it seems to work. The problem startet when the company rolled out additional security surveillence agents on the machines, I guess they slow down the connection establishment leading to a timeout. If I interpret wireshark captures correctly, this is what's happening.
Maybe making this timeout configurable would solve the problem?

I just tried updating to mvnd version `1.0-m6-m40`, unfortunately it has made no difference to this issue. The output can be seen here in CI - https://github.com/eXist-db/exist/actions/runs/4956482660/jobs/8866980235
The pertinent parts are:

I will test that next and come back to you...

I am not sure that is something we can test inside GitHub Actions CI as it runs one process after another and is non-interactive.

You can put those commands right after the mvnd invocation, possibly in an "on failure" block. GH actions has some special syntax for that. I am really curious, whether the daemon process is still up when the client gives up waiting. If it is not up then you need to find out what prevents it from starting, e.g. by trying to invoke that logged `java.exe -classpath ...` command directly.
If it is up, it would be interesting to see what state is it in, e.g. by inspecting its heapdump. Is it blocked by something? Is it just too slow (because the GHA machine is so underpowered)?

@gnodet Thanks for the configurable timeouts, however I think I am still seeing problems that this doesn't seem to help with.
When calling:
```
mvnd -D'mvnd.connectTimeout=90 seconds' --version
```
In GitHub Actions on the Windows and macOS runners this seems to still result in a:
```
Exception in thread "main" org.mvndaemon.mvnd.common.DaemonException$ConnectException: Timeout waiting to connect to the Maven daemon.
```

@adamretter could you please try with the latest mvnd release? Do all those installation steps work for you locally on a fresh Windows machine? It would be nice to see in which state is the daemon process when client gives up trying to connect. Is the daemon process alive at all - to check that , you could add some sort of windows counterpart of `ps | grep java` to your GH actions script. Is it listening on the requested port (I'd do `netstat -tulpen | grep java` on linux)?

I've created #772 to make the timeous configurable.
I've also raised the default socket connect timeout from 10 ms to 1 second. It seems the code messed between units, getting the time using `nanoTime`, adding microseconds to it...
