Maven Pre-Prepare Plug-In

You can use the Maven Pre-Prepare plug-in to pre-prepare a C-App pom.xml file for mvn package goal by enabling the system scope and system path. Given that mvn install goal is widely used compared to mvn package goal, this plug-in is an optional feature for a developer. This plug-in needs to be executed only after finalizing any artifact changes done in Developer Studio.

Creating WSO2 artifacts

Create your favorite artifact projects (ESB Config, Registry, Axis2 etc.) inside a Maven Multi Module project in Developer Studio.
Under the same Multi Module project, create a Composite Application project in which you will define which artifacts are to be packed.
Finalize any changes in the developed artifacts and select them in the C-App POM editor view.

Prepare artifacts for Maven package goal (using system-scope goal)

You can execute the plug-in from inside Eclipse or using the console.

It is always necessary to execute this plugin on the root of a Maven Multi Module project.
Multiple levels of Maven Multi Module projects are supported.
This plug-in traverses through all the sub modules of a project and maps system paths of artifacts to dependencies in the C-App pom file.
During the build process, you need to provide consent (Y/n) to proceed with changing of the C-App pom file with system scope and system path. Default input is Y.
If you need to update only selected C-App projects where multiple C-App projects are present, this consent can be provided differently.
If the build needs to be automated, this consent can be provided as an optional parameter in the mvn string:
mvn org.wso2.maven:wso2-maven-package-prepare-plugin:system-scope -DupdateDependencies=true

Execute Maven plug-in from inside Eclipse

Right-click the Maven Multi Module project and click Run as > Run Configurations.
In the dialog box that appears, double click Maven Build in the tree view. To select a base directory, click Browse Workspace and browse to the previously created Maven Multi Module project.
In the Goals field, enter org.wso2.maven:wso2-maven-package-prepare-plugin:system-scope and click Run.

Execute Maven plug-in from a console

Navigate to the previously created Maven Multi Module project location and enter mvn org.wso2.maven:wso2-maven-package-prepare-plugin:system-scope.

The pom file will now look like the following:

Now, you can proceed with mvm package goal.

Revert to default scope (using default-scope goal)

By replacing the previously used plug-in execution string with default-scope (as shown below), the C-App pom file can be reverted to its original state.

mvn org.wso2.maven:wso2-maven-package-prepare-plugin:default-scope
