Make - Build tools in Java

Every junior developer must be familiar with the basics of make tools.

Usually junior developers are not introduced to such tools early in their career.

That is bad...proper and efficient building, packaging or dependency management of a Java Application is something that needs time to master.

17Thursday, February 21, 2008

make build tools -

1. Apache Ant - ant.apache.org/Recommended Books:

Java Development with Ant - www.manning.com/hatcher/

Ant The Definite Guide -www.oreilly.com/catalog/anttdg2/index.html

18Thursday, February 21, 2008

make build tools - Maven, Ivy

2. Apache Maven - ‘software project management and comprehension tool’maven.apache.org/

3. Apache Ivy - ‘dependency manager’

Software Quality Tools

Some developers still ignore SQE toolsSome developers still ignore that such tools are integrated to their IDE via plugins.SQE Tools...increases the quality of your code base.Makes your life and your manager’s life easier.

20Thursday, February 21, 2008

Software Quality Tools

FindBugs - findbugs.sourceforge.net/PMD - pmd.sourceforge.net/CheckStyle - checkstyle.sourceforge.net/

21Thursday, February 21, 2008

Software Quality Tools

Do you want them integrated with your IDE(e.g Netbeans)? no..prob!

SQE project - sqe.dev.java.net/

Or you may check my simple guide for Netbeans 6.0http://urlb.org/lgm2

22Thursday, February 21, 2008

You should Unit test!!!

Still lots of development teams ignore unit testing during their development life-cycle.Even senior developers sometimes are not familiar with the basics of unit testing!!!That is bad...bad...bad...bad...bad!!!

23Thursday, February 21, 2008

Unit Testing for beginners

JUnit -www.junit.org/Book : JUnit in Action -/www.manning.com/massol/

Test NG - testng.org/doc/JUnit knowledge is considered mandatory for everyone!Encourage developers to unit test!!!

24Thursday, February 21, 2008

What about Versioning Systems

The most common problem with junior developers - proper use!There still even ‘senior’ developers who cannot properly update- merge their code with the repository.Proper use and knowledge of your versioning system saves time.

25Thursday, February 21, 2008

What about Versioning Systems

Try to focus on the versioning system you are using - learn its potential!

CVS - www.nongnu.org/cvs/SVN - subversion.tigris.org/

26Thursday, February 21, 2008

think before you shoot!

Think twice before you commit!Update before you commit!Don’t commit 10 minutes before you leave work - very very bad!Make one batch commit (lots of files) not 10000 single commits!Committing just to prove you did something DOES not help!

27Thursday, February 21, 2008

one last thing to remember!

Everybody makes mistakes - everydayThat is ok, no harm doneUnless it is the day before a release!!!!

Thank you for your time!
