Gradle build could not resolve this

[hoony0203]

Hello, I'd like to ask something.

1. When I add this library to gradle dependencies like below, then "Could not resolve" message occured.

implementation 'com.pointcx:mustache-security-spring-boot-starter'

Message is like this below

Could not resolve: com.pointcx:mustache-security-spring-boot-starter
Task :nothing UP-TO-DATE
Could not resolve: com.pointcx:mustache-security-spring-boot-starter

If you don't mind could you let me know about how can I solve this problem?

2. Or, confirm my using process wrong or not. I realize your source composed like Configuration class.
   Just paste dependencies insufficient?

So I'd like to know how could I use your mustache el tag. Thank you for reading.
