Maven deploy direct to Karaf instance?
Hi,
I'm having a little trouble following what should be a relatively
straightforward example. I am trying to directly deploy an artifact into a
running karaf instance using the mvn deploy:deploy-file command, as given
under the "Apache Maven" section of here
https://karaf.apache.org/manual/latest/users-guide/remote.html, but maven
fails with an error:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy-file (default-cli)
on project features: Failed to retrieve remote metadata
com.example:features:1.0-SNAPSHOT/maven-metadata.xml: Could not transfer
metadata com.example:features:1.0-SNAPSHOT/maven-metadata.xml from/to
ssh-repository (scp://localhost:8104/system): Error occurred while
downloading 'com.example/features/1.0-SNAPSHOT/maven-metadata.xml' from the
remote repository:Repository[ssh-repository|scp://localhost:8104/system]:
Exit code: 2 - \system\com.example\features\1.0-SNAPSHOT\maven-metadata.xml:
no such file or directory -> [Help 1]
There appears to be no such maven-metadata.xml files in any of the system
sub-directories of the instance.
Is this functionality still expected to be working? has anyone had any
experience doing something similar?
Cheers
Gary

It makes sense. I will make a try asap.

Hi JB,
I'm currently working with Karaf 3.0.4. I create a custom distribution and
within that work within instances, but I wouldn't think that should make a
difference.
As it's expected to work, I'll play with a few more scenarios, and with
4.0.1, when I next get chance. Of course it'd be great if anyone else could
do a quick test to see if it works for them.
Cheers,
Gary

It does not matter which directory once creation of additional directories is
required, does it? scp directly to system works just fine.

Weird, I already did it AFAIR (but maybe upload to deploy and not system).
Let me improve that.

In addition to the above: no, Karaf scp cannot create folder. Because scp by
design does not handle creation of directories. Karaf, surely, could have a
special scp implementation, but it does not. A simple test like 'scp -P 8101
~/test.txt karaf_host:/system/test/test.txt' demonstrates this. It fails
with 'Can not write to system/test/test.txt'. This is another confirmation
that maven-deploy-plugin cannot deploy to Karaf, even if it worked solely
via scp.
I am wondering what is the purpose of having invalid and obviously not
working example in the Karaf documentation.

While the protocol specified is 'scp', I can see that shell command
interpreter is expected by maven-deploy-plugin (by Wagon, to be more exact).
As I already mentioned, it tries to create directories on remote host by
using org.apache.maven.wagon.providers.ssh.ScpHelper. And 'mkdir' is used
for that as you can see from the implementation of
createRemoteDirectories() method
<https://maven.apache.org/wagon/wagon-providers/wagon-ssh-common/apidocs/src-html/org/apache/maven/wagon/providers/ssh/ScpHelper.html#line.341>
(some code omitted):
String mkdirCmd = "mkdir -p \"" + path + "\"";
executor.executeCommand( mkdirCmd );
At least this method is invoked on my system when I do 'mvn
deploy:deploy-file'.

Hi,
If you do, mvn deploy:deploy-file with scp, Karaf scp can create folder
in the system folder (it's not ssh, it's scp).
So, it should work with scp, not with sshexe.

Hi Jean-Baptiste,
Maybe you could clarify one thing for me. Maven Deploy Plugin works with
files through Wagon providers. During deployment it has to create
directories as per standard Maven repository layout -
groupId/artifactId/version. If deployment is performed to remote host via
SCP, mkdir command is issued for that.
Now the thing that I don't understand. Karaf shell exposed through SSH is
not a POSIX-like shell. It does not provide commands like mkdir. Due to this
I cannot get deployment using Maven Deploy Plugin working - it simply fails
on attempt to create a directory.
I am curious how that deployment example from the documentation could
possibly work.
Thanks.

Hi Gary,
yes, it should work (at least the scp part). The maven-metadata.xml is
only required for SNAPSHOT (not release). In your case, as it's your own
feature, Maven should update the maven-metadata.xml itself.
What Karaf version do you use ?
