Modular Add-on for JasperReports: Integration and Processor Workflow

The third part of the JasperReports modular add-on series focuses on practical development aspects. The author details how to integrate the library into Maven projects and create the first modular report. A key feature of this solution is the use of an annotation processor that automatically supplements JRXML templates with necessary parameters, datasets, and subreports during compilation, saving the results in target/generated-sources without modifying the original files. The article also addresses template ownership when using both a code generator and Jaspersoft Studio, while analyzing potential architectural weaknesses. This material is valuable for developers looking to automate the generation of complex reports and improve the structure of their JasperReports-based projects.
