This rule flags the use of unavailable third-party APIs so that you can assess the complexity of your migration.

If your application requires the third-party APIs, place the corresponding JAR files in a location that is visible to the application classloader, such as the WEB-INF/lib directory. If you do not have the JAR files or the license does not allow you to package them with your application, modify your application to remove the dependency on the third-party APIs.

A project is flagged once for each third-party API that is referenced.

For information about other APIs and SPIs that are not supported on Liberty, see Some APIs and SPIs are not available on Liberty.
