CAS cas-overlay-template

Spent quite a few days troubleshooting and building 6.4.4.2 from https://github.com/apereo/cas-overlay-template

Not wanting to question the build process I accepted the instructions and created my cas.war file which I promptly deployed to the appropriately supported tomcat server.

I kept on getting the following error NO matter what I did, I even tried adding the appropriate libraries to the tomcat build.

...

Needless to say it was quite frustrating even when I do know and see the error clearly. Was anyone able to use their build without modifying anything other than the "build.gradle" file?

Spent quite a few days troubleshooting and building 6.4.4.2 from https://github.com/apereo/cas-overlay-template

This is likely the root of the problem. If you consider reading the README.md file found at the very same referenced github repository, you will find:

Versions

  • CAS Server 6.5.0-SNAPSHOT
  • JDK 11

So what you are working with has nothing to do with 6.4.4.2.

However, if you do actually switch to the correct branch, 6.4, located here https://github.com/apereo/cas-overlay-template/tree/6.4 and then review the README file:

Versions

  • CAS Server 6.4.4.2
  • JDK 11

In summary, if you stay on the right branch, you will get the correct version and your fix is unnecessary.

After deployment I went into the directory that contained all the libraries:

-rw-r----- 1 root root   1391480 Jan  6 15:53 spring-boot-2.5.4.jar
-rw-r----- 1 root root    644836 Jan  6 15:53 spring-boot-actuator-2.5.4.jar
-rw-r----- 1 root root    534699 Jan  6 16:14 spring-boot-actuator-autoconfigure-2.5.4.jar
-rw-r----- 1 root root    561010 Jan  6 16:16 spring-boot-actuator-autoconfigure-2.6.1.jar
-rw-r----- 1 root root   1564883 Jan  6 15:53 spring-boot-autoconfigure-2.5.4.jar
-rw-r----- 1 root root     27774 Jan  6 15:53 spring-boot-configuration-metadata-2.5.4.jar

and noticed there where two versions of "spring-boot-actuator-autoconfigure-..."

Hmmm... that did not seem right. So I decided to dig around a bit and decided to change the "gradle.properties" file from:

springBootVersion=2.6.1

to

springBootVersion=2.5.4

./gradlew clean build

Deployed to Tomcat and it WORKED!!!

We were able to deploy and get up and running pretty quickly after this change.
