Using Libraries

• Library Wrapper Module
  • The whole application is based on modules.
  • It is desirable to integrate the external JAR file in the form of a module.
  • Enhances the consistency of the application as a whole.
  • You can also bundle multiple JAR files into a single module, after which you need no longer put the physical JAR files on the application classpath, as is normally done when developing applications.
• Two very important things:
  • It marked all packages in the third-party library with the attribute OpenIDE-Module-Public-Packages, making all these packages publicly accessible.
  • Marked the library it found in the ext/ folder with the Class-Path attribute, putting it on the module classpath.
• It is advisable to always use a library wrapper module when integrating a third-party library into an application.
