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’
19Thursday, February 21, 2008
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!
