The first step to have a maven repository. This stores the javax and oracle jars which are needed for compilation, You have to upload the needed jars into the repos. the others non commercial jars are downloaded automaticaly from public repositories and stored in the local repos. For a good description how to setup a repository see this guide on the theserverside. I use artifactory.
If you work in teams I think you already have subversion or cvs. This is necessary so maven can check out the code every X minutes for a complete rebuild.
Let's download maven
Now we are ready to setup a jdeveloper project . Maven needs a typical structure for a normal project and a webapp project. see the picture below. So you need to change the jdeveloper projects to this directory structure.
You also can do the other way around, make the directory structure, put in your code. Let maven compile the workspace and the download a maven plugin from some adf faces developers. And let this plugin generate jpr files. check out with subversion this url http://svn.apache.org/repos/asf/myfaces/trinidad-maven/trunk/maven-jdev-plugin for the plugin
Let's make a trunc folder with a model and viewcontroller subfolders. In the model we have a src folder with two subfolder main and test. In main\java you put in your java and xml's and in test your unit tests. The viewcontroller structure is a bit different you have here a webapp folder in src/main.
Now we ready the make the maven pom files. The first we make is the main pom where we put in the order of compiling the sub projects and shared used jar files. This pom.xml is located in the trunk directory
Here you see we have two projects model and view controller and one shared jar.
Here you have extra configuration elements for the issue management , in this case I use jira . If the build fails it makes a issue to the developer in jira . The second is subversion scm connection to check out the model code. The third is the continuum configuration who is has to email if there are changes in the build proces.
The build configuration is very import for adf bc ( bc4j) projects because the xml files are very important.
The viewcontroller pom looks like this
Dependency is now the model project
Now we can build the application in maven. the last step is installing continuum where we can load the main pom.xml and we now can configure when and how often it has to build .We also get a total overview about over build projects.
