How to use wagon-ssh-external instead of wagon-ssh?

Hi,

I am facing some problems deploying my project's site using sftp. For
testing purposes I thus want to switch wagons, namely from
org.apache.maven.wagon:wagon-ssh:1.0-beta-7 to
org.apache.maven.wagon:wagon-ssh-external:1.0-beta-7. However, even
adding the appropriate extension to my POM doesn't convince the
maven-site-plugin:3.0-beta-4-SNAPSHOT to pick a different wagon for the
sftp URI scheme.

 <extension>
   <groupId>org.apache.maven.wagon</groupId>
   <artifactId>wagon-ssh-external</artifactId>
   <version>1.0-beta-6</version>
 </extension>

At least, I still get the same exception, which clearly says that I am
using the JSch-based Wagon and not an external ssh process:

Caused by: 3: Permission denied
        at
com.jcraft.jsch.ChannelSftp.throwStatusError(ChannelSftp.java:2291)
        at com.jcraft.jsch.ChannelSftp.mkdir(ChannelSftp.java:1701)
        at

        at
org.apache.maven.wagon.providers.ssh.jsch.SftpWagon.putDirectory(SftpWagon.java:271)
        ... 25 more
[ERROR]

Any suggestions? How does the maven-site-plugin map URI schemes to wagons?

Also, is there any configuration option / system property to make the
wagon more chatty? Just running "mvn site-deploy -X" doesn't produce
enough information to track down what's actually going over the wire. :-(

Best wishes,

Andreas Sewe

I am afraid, it didn't help: When declaring a plugin dependency, the maven-site-plugin now has both org.apache.maven.wagon:wagon-ssh-external:jar:1.0-beta-7 and org.apache.maven.wagon:wagon-ssh:jar:1.0-beta-6 as a dependency, but it still insists on using the latter for sftp URIs. :-(

Apologies for not noticing that detail sooner. The external wagon doesn't have a handler for sftp - only scpexe.

Hi Wayne,

that's something I couldn't get past Maven 3. Also tried 
<optional>true</optional> and a system-scoped dependency with an invalid 
<systemPath>, but to no avail.

No, it didn't. :-(

Thanks for the suggestions, though.

Could you maybe set a dependency to that jar, and set the scope to
"runtime"? Don't know if that will help though.

good point. Unfortunately, I don't see a way to do that. It looks like I 
can only use <exclusions> to exclude *transitive* dependencies of a 
plugin. At least the following plugin dependencies clause doesn't work:

   <dependencies>
     <dependency>
       <exclusions>
         <exclusion>
           <groupId>org.apache.maven.wagon</groupId>
           <artifactId>wagon-ssh</artifactId>
         </exclusion>
       </exclusions>
     </dependency>
   </dependencies>

org.apache.maven.project.ProjectBuildingException: Some problems were 
encountered while processing the POMs:
[ERROR] 
'build.plugins.plugin[org.apache.maven.plugins:maven-site-plugin].dependencies.dependency.artifactId' 
for null:null:jar is missing. @ line 151, column 27
[ERROR] 
'build.plugins.plugin[org.apache.maven.plugins:maven-site-plugin].dependencies.dependency.groupId' 
for null:null:jar is missing. @ line 151, column 27
[ERROR] 
'build.plugins.plugin[org.apache.maven.plugins:maven-site-plugin].dependencies.dependency.version' 
for null:null:jar is missing. @ line 151, column 27

I am afraid this is an incarantion of 
<http://jira.codehaus.org/browse/MNG-2163>. :-( Or am I mistaken?

Best wishes,

Andreas Sewe

Perhaps you need to exclude the one you don't want?  Maven doesn't
recognize one as a replacement for the other, it just sees two
separate artifacts.

I think in the Maven 3 version of the site plugin, you need to add the wagon as a dependency of the site plugin, instead of as an extension (which only applies to the core deployment components).
