Hi all,
I need to implement a special kind of file wagon to fetch artefacts from
existing file shares with a predefined structure. To realize that wagon,
I read a lot of websites, but I'm still not able to call a simple Wagon
which is only writing to System.out.
My Scenario:
A simple Execute-Plugin uses the CustomWagon-Plugin to access a
HelloWorld-Plugin on the local file system. That "access" is currently
only a dummy configuration and the only reason of it is, to make use of
the CustomWagon-Plugin while accessing the protocol testfs://...
But sadly I do get always the following Exception:
org.apache.maven.wagon.TransferFailedException: Unsupported Protocol:
'testfs': Cannot find wagon which supports the requested protocol:
testfs
Even if it is a little bit long, but I like to offer you as much
information as possible about my problem. Therefore I added the used
configuration below.
Thank you 1000x for all your help
Regards Matthias
