如何导入 gradle 依赖项

Question

I'm learning Spring Boot. I already declare hateoas dependency and build it successfully. (I use Gradle). But I still can't import EntityModel. What is wrong?

// build.gradle
dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-hateoas'
    runtimeOnly 'com.h2database:h2'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

Answer 1

Make sure you build the project so the dependencies get downloaded, using the build tool in your IDE or from the Terminal first.

Try importing:

 import org.springframework.hateoas.EntityModel

and in gradle try the artifact org.springframework.hateoas:spring-hateoas

What a surprise. Today, I just open my IDE then the problem is solved.

// build.gradle
dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-hateoas'
    runtimeOnly 'com.h2database:h2'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

I tried these command:
