sshExecutable from settings.xml ignored

[liefke]

Affected version

3.21.0

Bug description

I recently upgraded maven-site-plugin in one of my projects (Fastnate) to 3.21.0.

When running site:deploy the new version ignores the sshExecutable configuration option from my settings.xml. Instead it tries to execute ssh in batch mode, which fails, because I haven't configured ssh to connect without a password prompt.

It seems that the problem was introduced in 3.20.0, because when switching back to 3.12.1, the plugin respects sshExecutable, while 3.20.0 ignores it. So I stay with version 3.12.1 until this is fixed.
