Import error even though dependencies exist

Question

When I add import org.springframework.data.annotation.Id; to my Java file I get this error:

The import org.springframework.data cannot be resolved

My immediate thought is that I'm missing a dependency but I don't think this is the case.

Here's the dependencies from my build.gradle .

dependencies {
    compile('org.springframework.boot:spring-boot-starter-webflux')
    compile('org.synchronoss.cloud:nio-multipart-parser')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('org.springframework.boot:spring-boot-starter-data-mongodb-reactive')
    compile('org.projectlombok:lombok')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('io.projectreactor:reactor-test')
}

Also, I've applied these plugins:

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

Am I missing something, or how do I get past this issue?

Additional Info.

I ran ./gradlew clean build --refresh-dependencies --debug . Here is an extract from the log:

I checked ./gradlew dependencies org.springframework.boot:spring-boot-starter-data-mongodb-reactive -> 2.2.0.BUILD-SNAPSHOT contains org.springframework.data:spring-data-mongodb:2.1.4.BUILD-SNAPSHOT which contains org.springframework:spring-context:5.1.3.RELEASE -> 5.1.4.BUILD-SNAPSHOT . Is it possible org.springframework:spring-context:5.1.3.RELEASE -> 5.1.4.BUILD-SNAPSHOT is not a compatible version?

Answer 1

This class org.springframework.data.annotation.Id belongs to the Spring module org.springframework.data:spring-data-commons . So if you want to import classes from this module you should add a dependency to it:

dependencies{
     compile("org.springframework.data:spring-data-commons")
     // others ...
}

Note you should also be able to import this class without this explicit dependency to spring-data-commons module, since this module is already part of the transitive dependencies of your project (from spring-boot-starter-data-mongodb-reactive ). This means that with your current build.gradle setup, you should be able to import this class without error.

./gradlew dependencies 

+--- org.springframework.boot:spring-boot-starter-data-mongodb-reactive -> 2.0.0.RELEASE
|    +--- org.springframework.boot:spring-boot-starter:2.0.0.RELEASE (*)
|    +--- org.springframework.data:spring-data-mongodb:2.0.5.RELEASE
|    |    +--- org.springframework:spring-tx:5.0.4.RELEASE
|    |    |    +--- org.springframework:spring-beans:5.0.4.RELEASE (*)
|    |    |    \--- org.springframework:spring-core:5.0.4.RELEASE (*)
|    |    +--- org.springframework:spring-context:5.0.4.RELEASE (*)
|    |    +--- org.springframework:spring-beans:5.0.4.RELEASE (*)
|    |    +--- org.springframework:spring-core:5.0.4.RELEASE (*)
|    |    +--- org.springframework:spring-expression:5.0.4.RELEASE (*)
|    |    +--- org.springframework.data:spring-data-commons:2.0.5.RELEASE (*)
|    |    \--- org.slf4j:slf4j-api:1.7.25

So maybe you have a synch issue in your project, try to clean/close/reopen it.

Answer 2

Are you sure that data is part of the imported packages? It seems to me that you need to add org.springframework.data to your gradle file. You can see here that data is different package.
