Manen Ant SVN

  1. Apache build projectsA practical session on Apache Maven, Ant and Subversion By. S. Suhothayan & Prabath Abaysekara
  2. Subversion (SVN) If more than one developer is working on a project - how can they all make changes to the source code...?
  3. Why version control? This gives us a history of a software project If we accidentally delete some code, we can look for an older version that still has the code We can see who made what changes Serves as a backup
  4. Terminology Repository: a storage location for projects that SVN will manage Checkout: to download a copy of a project from a repository Commit: to upload files to a repository after making changes Update: to download the latest versions of files from a repository when your local copies are out of date
  5. How its done… More than one developer is working on a project... from: OpenMRS
  6. How its done… more than one developer to works on the same revision file... and trying to commit at the same time! from: OpenMRS
  7. How its done… What if the changes are on the same line !!! from: OpenMRS
  8. from: OpenMRS
  9. Ant A software tool for automating software build processes Similar to MAKE, but:  Written in and developed primarily for Java  Uses XML scripts
  10. How Ant build files written? Build-scripts are created from existing Ant-tasks. The Ant tasks do not prescribe any conventions or configuration. Therefore the definition of project layout is your responsibility. Advantage  You have full control of whatever you are doing Disadvantage  Can become a problem in bigger projects.
  11. How to run Ant ? Can be run from the command line By default the command line client looks for a build script build.xml in the current directory > ant To use a different build script, we have to specify it > ant -buildfile other.xml
  12. Targets Build scripts contain targets, the different jobs that they can performed We can specify the name of the target to run the specific target . > ant compile Note: If nothing specified will run the default target
  13. Maven A software project management and comprehension tool.
  14. What it Maven? Maven = “Ant With Convention Over Configuration“ Directories  Source, Tests, Resources Goals  Clean, Test, Deploy, Package, Install, Site... But... you have to learn the conventions!
  15. Maven Lifecycle validate Validate the project is correct and all necessary information is available compile Compile the source code of the project test Test the compiled source code using a suitable unit testing framework. package Take the compiled code and package it in its distributable format, such as a JAR. verify Run any checks to verify the package is valid and meets quality criteria install Install the package into the local repository, for use as a dependency in other projects locally deploy Done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.
  16. Create a project With the archetype mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=org.apache.meetup -DartifactId=calcualtor-app
  17. Dependencies Dependencies are uniquely identified by their  Group  Artifact  Version Declare dependencies in the POM and the Maven will find it for you!
  18. Dependency management The real strength! You only have to declare the dependencies –  maven will download them  setup the classpath and  even deploy the dependencies with your application. Maven manages not only the direct dependencies - but even the dependencies of the dependecies (transitive dependencies)
  19. MavenRepositories Repositories are used to host dependencies1. Remote The servers that hold released binaries e.g. Artifactory, Nexus2.Local ~/.m2/repository
  20. MavenPlugins Reporting Test Coverage (Sonar) Javadoc auto-generation CheckStyle FindBugs Ant
  21. Releasing your project Single command to deploy  Pushing artifact to server (Almost) Single Command To Release your project! mvn release:prepare release:perform
