 Build Engineering is an essential Configuration Management function that can significantly impact the Software Development effort in many important ways. I have worked extensively with building applications using Apache Ant, MS Build and GNU Make (along with other classic versions of Make). Another key build tool is Maven which seems to be gaining in popularity with many developers. I worked with Maven 1.0.2 and then, later, Maven 2 and found that Maven had many advantages and also a number of real challenges. This article is about reviewing an existing Maven build and looking for ways to improve and refactor the existing build. Closely related activities are “mavenizing” an existing non-maven build and addressing Maven build anomalies.

 In my previous article I introduced Maven, the maven cycle and discussed the local repository. Maven has a lot of implied structure that you need to be aware of or you just won’t understand why things are happening behind the scenes. While Maven is great is presenting a consistent set of standards, sometimes it can be hard to figure out what happening behind the scenes. POMs are key to directing maven to do your bidding, they can also be a real challenge to decipher.

It’s become increasingly popular to combine Agile practices with Lean principles as described in Mary and Tom Poppendieck’s work on Lean Software Development.
In Lean there are seven Lean Principles:

 Maven is a popular build framework that is used by many technology professionals to manage large scale java application development. The Apache Maven website (http://maven.apache.org) states that "Maven is a software project management and comprehension tool". Maven builds are based upon a project object model (POM) which is coded in XML. Maven is used to manage a project's build, reporting and documentation from a central place. I have worked with both Maven 1.0.2 and the very popular Maven 2. For this article I used Maven 2.2.1 on RHEL 5.3.

Do you need agents? |

 Recently, I worked with a few of my colleagues to implement an Application Lifecycle Methodology (ALM) solution that included a full build infrastructure that provided most of the functionality of a Continuous Integration (CI) server. This was part of a rich and powerful technology solution that managed all aspects of the Software Development Lifecycle. During this effort, I realized that some of my colleagues did not fully grasp the scope and purpose of using a build agent.

Running a Makefile from Ant |

 I recently got an assignment where I needed to run all of my build scripts from Ant. The reason was simply that the ALM solution that I was implementing could only accept build status return codes from an Ant directive. Since the project involved C/C++ all of the build scripts were written using GNU Make. My goal was to be able to execute the Makefile from within an Ant build.xml and receive the return code back in the Ant script. Here is how I approached the solution.

Rules With Multiple Outputs in GNU Make |
|
|
Tuesday, 04 August 2009 00:00 |
 One problem that Makefile writers sometimes have is the need to write a single rule that produces multiple output files, to accomodate tools that don't fit the standard one-command-one-output model generally assumed by make. The classic example is bison, a parser generator used in crafting compilers and interpreters. Bison takes an input file like parser.i and generates both parser.c and parser.h. The Makefile hacker is left with a dilemna: how do you express this relationship in GNU Make syntax? In this article we'll look at the obvious answer and why it is wrong. Then we'll look at a few alternatives, including the one and only way to truly capture the relationship in GNU Make syntax.
