RE: Deploy with SFTP tries to cd to parent too many times
I can't help wondering if this entire discussion is continuing because of semantics. I think you are talking about two uses of the word deploy. For a Maven Deploy a standard Maven repository is probably best. For a Production Deploy we must use whatever the production environment provides. If you are 'deploying' an artifact to be acquired by another Maven project then it is a Maven Deploy. If you are 'deploying' a product into a production environment (where it will execute, for example) it is a Production deploy. How can we de-obfuscate the word deploy that was overloaded by the Maven use? Also, consider the other overloaded words: package, install, validate, verify, etc. I suppose, on a Maven forum, the words should be used the Maven way. But ,then how do you ask about the other contexts? !-- Frank Gorham-Engard → Be kinder than necessary.

[You probably don't want to hear this, but you should hear it anyway] Use A Maven repository manager and then you will not be worrying about sftp at all.

This appears to be a bug that affects any repository whose SFTP host disallows access to the root directory. Here's what I know so far: By instrumenting JSch (which does the actual SFTP commands), I can see that the problem occurs when JSch issues a cd .. too many times. In fact, it does cd .. all the way back to the root and just keeps on going, doing a cd .. several more times. Ordinarily this wouldn't be a problem, but when the permissions of the SFTP user don't allow cd'ing into the root directory (for increased security), there will be a permission denied error, which in turn causes the build to fail. Assuming that the security policy of the server cannot be altered, I'm trying to figure out if there's a way to resolve this on the client side. However, I have no idea why Deploy is trying to cd .. so many times. For example, if I configure the snapshots repository as something like: sftp://example.com/home/myuser/myrepository/snapshots Then there's no need to cd anywhere above the snapshots directory. But Deploy does exactly that, for some reason. From studying the logs I put into JSch, Deploy appears to be trying to check the repo for previous artifact metadata, and to do so it issues a cd into a directory deep in the hierarchy. But because this artifact doesn't happen to be in the repo, the directory does not exist, yet the code continues on as if it does. It then issues a series of cd .. commands, which, if the directory existed, would probably bring it back to some appropriate spot in the hierarchy, but because the first cd failed, it starts from a much higher level and ends up ascending well past the root.

Actually no, AFAIK use http direct, so it's not the WebDAV client at all. Your client would be better served using a Maven Repository Manager than a website backed by an SFTP share. Drink the Kool-aid, I recommend Nexus, easy to set up and the staging support in the professional edition is cool... add in that they can then use it to proxy the public repos and save bandwidth and it's almost a no-brainer... but by all means if you can fix SFTP support that would also be cool On 6 September 2010 11:49, Trevor Harmon tre...@vocaro.com wrote: On Sep 6, 2010, at 3:17 AM, Stephen Connolly wrote: Because they all deploy via http/https So in other words, use WebDAV and then I will not be worrying about SFTP at all.

Re: Deploy with SFTP tries to cd to parent too many times
You are dancing around the edges. Get Nexus up and running and start to enjoy using Maven. It is free. It is easy to install and configure. It makes finding artifacts painless and encourages/forces you to deploy properly. It gives a great deal of transparency to the whole Maven process. There are other repository packages but Nexus is the one that I know and it made our lives a lot easier. We are a small team of 3 but it was well worth the time to get it up and running.
