Gradle overlay CAS 5.0.0 + cas-server-support-ehcache-ticket-registry: some libraries are doubled in WEB-INF/lib

[Yauheni Sidarenka]

I have bare Gradle Overlay Git repo of CAS 5.0.0, master branch, latest commit - 426847c1690723401a82f1c274c10d7a4a210107.
OS: Windows 7 Pro x64
JDK: Oracle 8u60

When I add in cas/build.gradle line

compile "org.apereo.cas:cas-server-support-ehcache-ticket-registry:${project.'cas.version'}"

after executing gradlew clean build these libraries will appear twice (two versions) in WEB-INF/lib  in resulted war file (version of library that was added by this dependency is in yellow):

How to disable extra libraries and which are correct ones?

[Yauheni Sidarenka]

There is a partial solution for this.

When I replace this line:

apply from: 'https://raw.githubusercontent.com/apereo/cas/master/gradle/overrides.gradle'

in cas/build.gradle file with the following line:

apply from: 'https://raw.githubusercontent.com/apereo/cas/5.0.x/gradle/overrides.gradle'

only one library is still doubled and it is HikariCP.
Even if I write:

apply from: 'https://raw.githubusercontent.com/apereo/cas/5.0.x/gradle/overrides.gradle'
ext["hikariVersion"] = "2.5.1"
ext["HikariCP.version"] = ext["hikariVersion"]

to make something like in that overrides.gradle file, mentioned library is doubled again.

By the way, I have noticed that "yellow" version of HikariCP comes in from Spring Boot.

Any ideas?

[Yauheni Sidarenka]

I have solved this problem.

Instead of writing this

ext["hikariVersion"] = "2.5.1"
ext["HikariCP.version"] = ext["hikariVersion"]


in the top of cas/build.gradle file, I have added this

compile "com.zaxxer:HikariCP:2.5.1"

to dependencies section.

The solution is pretty straightforward but it saves my time.

Many thanks to everyone!

Hi all,

I have realized after guessing game, that

ext["HikariCP.version"] = ext["hikariVersion"]

does not help because it should be

ext["hikaricp.version"] = ext["hikariVersion"]

Looks like it is a bug in spring-boot Gradle plugin.

By the way, variable hikariVersion is unnecessary in CAS Gradle overlay project, it is only used in full distribution repository in gradle/dependencies.gradle file to create dependencies.

So, the solution can be either

ext["hikaricp.version"] = "2.5.1"

somewhere in the top of cas/build.gradle file or

compile "com.zaxxer:hikaricp:2.5.1"

in dependencies section in the file mentioned above.

[Yauheni Sidarenka]

Sorry for misprinting.

The line in dependencies section must be

compile "com.zaxxer:HikariCP:2.5.1"

instead of

compile "com.zaxxer:hikaricp:2.5.1"

I do apologize.

apply from: 'https://raw.githubusercontent.com/apereo/cas/5.0.x/gradle/overrides.gradle'

This could be even improved using concrete version of file from commit tagged for release:

apply from: "https://raw.githubusercontent.com/apereo/cas/v${project.'cas.version'}/gradle/overrides.gradle"
