Crystal Reports for Eclipse Developer Guide

Using Deployment Assistance

When you deploy an application that includes the Crystal Reports facet, deployment assistance is provided that analyzes your project to make sure that all of the JAR files and libraries that the project requires are copied correctly.
The deployment assistance feature will run when the Validate, Run, or Debug actions are selected. If required driver JAR files are missing from the project, it will look for them in the Engine classpath first, and then it will look in the original saved location. If the required files cannot be found, an error will be displayed in the Problems view, otherwise, an Info message will be displayed, indicating success.

Note: The deployment assistance feature does not overwrite existing files.
