RVM 无法为 Jenkins 构建加载

Question

我正在尝试在我的企业中部署一个实验性的 Rails 应用程序。这里的一切都是为 Java 开发准备的，所以我必须开辟新天地才能获得公司对 Rails 的认可。

我需要使用 Jenkins CI (v. 1.580) 在办公室的 CentOS（版本 5.9）暂存服务器上部署我的 Rails 4.1.4 应用程序（ruby-2.1.2），作为我之前的概念证明将允许应用靠近生产服务器。

我在 Jenkins 中安装了以下插件并重新启动：Hudson Ruby 插件、rvm、Rake 插件、ruby-runtime、用于 Jenkins 的 RubyMetrics 插件、GIT 客户端插件、GIT 插件、GitHub API 插件、GitHub 插件

在 RVM 初始化脚本期间，Jenkins 构建似乎失败，输出如下。

我的 Jenkins .bashrc 文件如下所示：

#/var/lib/jenkins/.bashrc
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

还有.rvmrc：

#/var/lib/jenkins/.rvmrc
export rvm_trust_rvmrcs_flag=1 # always trust project .rvmrc
export rvm_install_on_use_flag=1 # auto install rubies
export rvm_gemset_create_on_use_flag=1 # auto install gemsets

我已尝试使用多用户说明对 RVM 进行 nuking 并重新安装，并确保我的 jenkins 用户是 rvm 组的成员。

我的构建脚本如下所示：

source ~/.bashrc         # Loads RVM
cd .      # Loads the RVM environment set in the .rvmrc file
# set env vars
#export GEM_PATH=/usr/local/lib/ruby/gems/1.2/gems
#export CI_REPORTS=results
export RAILS_ENV=test
#cp config/database.yml.example config/database.yml  
# creates a database.yml
bundle install           # Installs gems
rake db:schema:load      # Loads all the database schema
rake                     # Runs RSpec tests

这是来自 Jenkins 的完整控制台输出

我通过反复试验解决了这个问题：

通过在 .bashrc 中交换这些行：

#/var/lib/jenkins/.bashrc
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

并对我的构建脚本进行以下更改：

#!/bin/bash
source $JENKINS_HOME/.bashrc
rvm use ruby-2.1.2@datapoc
# Set "fail on error" in bash
set -e
# Do any setup
# e.g. possibly do 'rake db:migrate db:test:prepare' here
#cp config/database.example.yml config/database.yml
bundle install
rake db:schema:load
rake
