A second way, if you just need want to reuse code, is to write normal classes and export them in the bnd file. We use that often for data transfer objects, since we need them in various modules.
// Note: Uses Lombok to create getters, setters
@NoArgsConstructor
@AllArgsConstructor
public class CheckDownloadDTO {
@Getter @Setter
private String downloadURL;
@Getter @Setter
private boolean downloadPossible;
...
}
You can, of course, add all kinds of methods to such classes, to create a simple library.To make them available to other modules you need to export them in the bnd.bnd file:
Export-Package: my.package.with.dto, my.otherpackage.with.something
Note: I recommend to create an extra package for dto classes. Don't add it to an existing package since it will also export stuff by default. And you will overwrite the automatically generated export directive with yours, which could cause problems. It can be fixed, but it requires some understanding what happens.
Note 2: If you use @Component/@Reference the bnd stuff is created automatically for you.
