The project depends on the Annotation Processor. When opening this project in IntelliJ IDEA for the first time, you may notice that some code that should have been automatically generated is missing. To resolve this, you can choose any of the following methods:
-
First, run the
./mvnw installor./gradlew buildcommand in the project directory from the command line to generate the code, and then open the project with IntelliJ IDEA. -
Open the project directly with IntelliJ IDEA, ignoring the IDE errors temporarily. After the dependencies are downloaded, run the project's unit tests. All IDE errors will automatically disappear, and the application will start correctly.
This project supports both pom.xml and build.gradle, meaning it supports both Maven and Gradle.
When opening this kind of project for the first time, IntelliJ will ask how to open it. Make your choice.
If you want to switch the opening method, exit IntelliJ, delete the hidden .idea directory in the project, and then reopen the project with IntelliJ and make a new selection.
After ensuring that the missing code has been generated and recognized by IntelliJ, you can directly run any unit test.
