ruby - RVM and Jenkins setup

Question

I am new to Jenkins CI. I'm install RVM in my remote Jenkins and when I execute below shell.

#!/bin/bash -x
source ~/.bashrc
rvm use 1.9.3@rails-3.2.3

I get following errors.

+ source /var/lib/jenkins/.bashrc
++ PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/var/lib/jenkins/.rvm/bin:/var/lib/jenkins/.rvm/bin
+ rvm use 1.9.3@rails-3.2.3

RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal settings to allow shell login.
Please visit https://rvm.io/workflow/screen/ for example.

What does it mean? I don't have any idea. Please help me.

UPDATED: I'm tried below script but I still get errors:

#!/bin/bash -x
source /home/zeck/.bashrc
[[ -s ".rvmrc" ]] && source .rvmrc
export RAILS_ENV=test
bundle install

Errors:

/tmp/hudson457106939700368111.sh: line 5: bundle: command not found
Build step 'Execute shell' marked build as failure
Finished: FAILURE

Jenkins build shell can't detect RVM, gemsets and gems. What should I do?

UPDATED 2: Therefore jenkins can't detect ruby.

+ ruby -v
/tmp/hudson2505951775163045158.sh: line 5: ruby: command not found
Build step 'Execute shell' marked build as failure
Finished: FAILUR

I'm not using any jenkins plugn and I'm just run script from Build->Execute shell section.

Answer 1

As the error message suggests, RVM expects an login shell. Changing the hashbang line to #!/bin/bash -xl should resolve this.
