Spring Security SAML Project, Gradle Problems

Gradle scripts provided by Spring Security SAML project, https://github.com/spring-projects/spring-security-saml when executed fail to run as expected.  Based on some random posts on the web replaced the dependencies
from:
        classpath("org.springframework.build.gradle:propdeps-plugin:0.0.3")
        classpath("org.springframework.build.gradle:docbook-reference-plugin:0.2.4")
to:
        classpath("org.springframework.build.gradle:propdeps-plugin:0.0.7")
        classpath("org.springframework.build.gradle:docbook-reference-plugin:0.2.7")
 
in the file build.gradle.  After making the above changes, was able to run gradle eclipse to create eclipse project, and gradle clean build to build from the command prompt.
