Importing war file from a war module into a distribution module

Help/Discuss

History of this issue is here on this stackoverflow post how-to-build-distribution-package-in-multi-module-gradle-project

I have a test project setup on github github https://github.com/KiranMohan/study-spring-boot.

This is the project setup of interest.

include ':sb-2.1-multi-package', ':sb-2.1-multi-package:hello-rest-lib', 
        ':sb-2.1-multi-package:hello-rest-standalone-jar',
        ':sb-2.1-multi-package:hello-rest-war'
include 'sb-2.1-3pp-resources'
include 'sb-2.1-build'

However adding hello-rest-war to sb-2.1-build.tar.gz fails.

* What went wrong:
Execution failed for task ':sb-2.1-build:distTar'.
> Could not resolve all files for configuration ':sb-2.1-build:javaDeps'.
   > Could not find org.springframework.boot:spring-boot-starter-tomcat:.
     Required by:
         project :sb-2.1-build > project :sb-2.1-multi-package:hello-rest-war

* Try:

The war file in hello-rest-war do get compiled and built correctly if sb-2.1-build is removed from the project setup. So I assume something is wrong with the build.gradle file of sb-2.1-build module.

Please help me resolve this issue.

Update:

The errors are resolved after changing the below line in hello-rest-war/build.gradle
providedCompile "org.springframework.boot:spring-boot-starter-tomcat"
to
providedCompile "org.springframework.boot:spring-boot-starter-tomcat:$springBootVersion"

Seems to be a bug either in spring boot gradle plugin or with gradle itself that Version is not resolved for providedCompile dependency.
