I am trying to deploy my application.
Before I try to deploy to the actual server, I am using my own computer as
the remote repository.
<distributionManagement>
<snapshotRepository>
<id>snapshots</id>
<name>Repository for snapshot versions of company jars</name>
<url>scp://mymachine/srv/maven/snapshot</url>
</snapshotRepository>
<repository>
<id>releases</id>
<name>Repository for release versions of company jars</name>
<url>scp://mymachine/srv/maven/releases</url>
</repository>
</distributionManagement>
I have build extensions for both wagon-ssh and wagon-ssh-external version
2.4. SSH is up and running on my localhost.
Does it not work because I an deploying to localhost via SCP? I have tried
to add server into settings.xml for mymachine with my username and password.
That did not work.
I have no problem with trying scp manually:
scp myApp-2.4.0.jar
user@mymachine:/srv/maven/releases/com/myCompany/myApp/2.4.0/
Though I had to mkdir all of /com/myCompany/myApp/2.4.0/ before running scp
manually.
Using distributionManagement repository url with file:///srv/maven/releases
works just fine. Buth I want to be able to use SCP since I will be running
the build on Jenkins and it will deploy to another server location.
user@mymachine:~/workspace/myApp> mvn clean deploy
