How to Add a User-Defined Library
Question
In the development of the Spark application, users may add a user-defined dependent library which is different from the sample project. This section describes how to add a dependent library with user-defined codes into the project.
Answer
- On the main page of the IDEA, choose to access the Project Structure page.
- Select the Libraries tab, click the icon "+" on the following page, and add the local dependent library. Figure 1 Add the Dependent Library
- Click Apply to load the dependent library and click OK to complete the configuration.
- Add the dependent library when building Artifacts. This is because the user-defined dependent library does not exist in the operating environment. By adding the library, the created jar contains the user-defined dependent library, which ensures that the Spark application runs properly.
- On the Project Structure page, select the Artifacts tab.
- Click the icon "+" and select Library Files in the right window to add the dependent library. Figure 2 Add Library Files
