Jenkins 有两类config.xml：

在Jenkins home之下的config.xml是Jenkins server的配置文件。

另外在每个job或project自己的目录下，还有一个config.xml。它包含了是这个job的配置信息。

The Jenkins home directory contains all the details of your Jenkins server configuration, details that you configure in the Manage Jenkins screen.

A user appearing in this list cannot necessarily log on to Jenkins.

SCM user

(People who make changes to code in a source code repository that Jenkins is monitoring)

It is a good idea for developers to use their SCM username here: in
this case, Jenkins will be able to work out what users contributed to the SCM changes
that triggered a particular build.

Post-build Actions 对应了 config.xml中的 <publishers>

builder 就对应build

Source Code Management  <scm class="hudson.scm.SubversionSCM">

 Trigger<triggers class="vector">

portfolio controller builder-maven ， publishers：ant merge.results

portfolio package：builder-ant  target：portfolio.packaging。 publishers没有。

每个job下面都有一个workspace，里面有hudson_migration需要的所有ant脚本。

同时 workspace/trunk下 对于一个项目有两个文件：

portfolio

portfolio_pom.xml

Indeed, Continuous Delivery can be viewed as Continuous Deployment
with the final step (deployment into production) being a manual one dictated by
the business rather than the development team.
