eclipse sts gradle multimodule project problem - eclipse

Question

Using Eclipse STS 4.10 / linux .
I have a multimodule project like :
-rootFolder
-web (web app)
-dataservice (services, domain logic)
-datadef (model,repositories)
web has dataservice as a dependency
build.gradle shows:
dependencies {
compile project(':dataservice')
implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
implementation 'org.springframework.boot:spring-boot-starter-web'
///
}
dataservice has datadef as a dependency
build.gradle shows:
dependencies {
compile project(':datadef')
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
///
}
What I cannot achieve is datadef-1.0.0-SNAPSHOT.jar being included in dataservice-1.0.0-SNAPSHOT.jar file . Both are getting included in web.app though.
Sometimes eclipse "looses" reference on dataservice the datadef project and treat anything from datadef as an error.
Pasting dataservice project .classpath file. It shows the dependency on datadef.
<classpath>
<classpathentry kind="output" path="bin/default"/>
<classpathentry output="bin/main" kind="src" path="src/main/java">
<attributes>
<attribute name="gradle_scope" value="main"/>
<attribute name="gradle_used_by_scope" value="main,test"/>
</attributes>
</classpathentry>
<classpathentry output="bin/main" kind="src" path="src/main/resources">
<attributes>
<attribute name="gradle_scope" value="main"/>
<attribute name="gradle_used_by_scope" value="main,test"/>
</attributes>

Thank you.
