Deploy: SCP Task Error (java.lang.NullPointerException)

William Raendchen

Hello,

I'm setting up Bamboo for the first time.

I did a successful build and then wanted to do a deploy, including an SCP task.

I get the error message "Error occurred while running Task 'copy files(3)' of type com.atlassian.bamboo.plugins.bamboo-scp-plugin:scptask." (See full log below).

Currently I have no idea what the issue might be.
The SSH credentials work as an SSH task in the same job (ls -lsah) completes successfully.
The task config looks like this:


I installed Bamboo on my Windows 10 machine for testing purposes. I didn't install any extra software so far, outside from Bamboo and adding JAVA_HOME to my PATH to make it run in the first place.
I'm running start-bamboo.bat in an administrator shell

The error cause seemed to be, that no artifact was configured in my Build plan -> Default Job.
I added an artifact simply with the pattern "**/*", which clones all files from the working directory, except CVS folders by default.

Afterwards I got another error "Unable to download artifact Shared artifact: ..."
Browsing the forum for this error, it turned out changing (or adding) artifacts after configuring your deployment job can destroy the job and you just have to reconfigure the whole project from scratch.

I did that and now everything is working like a charm.
I hope this info helps some newcomers stumbling on the same problem, and that maybe the error messages / instability when modifying artifact definitions get addressed at some point.

Cheers, William
