Amazon Corretto Requirement cas 7.x.x

[Emmett MacDonald]

It seems as though amazon corretto has become a new build requirement for cas overlay 7.x.x. Does anyone know why this is?

Not actually the case. 

Here's the successful build of overlay template (7.1.0-SNAPSHOT), freshly cloned from here: https://github.com/apereo/cas-overlay-template

JDK 21 from Zulu:

> java -version

openjdk version "21.0.4" 2024-07-16 LTS
OpenJDK Runtime Environment Zulu21.36+17-CA (build 21.0.4+7-LTS)
OpenJDK 64-Bit Server VM Zulu21.36+17-CA (build 21.0.4+7-LTS, mixed mode, sharing)

>./gradlew clean build

I’ve built it successfully with just OpenJDK.

I've just tried with azul openjdk (https://www.azul.com/downloads/#zulu) but I keep getting the same error.

There's is this setting in gradle.properties:

# This property controls the JVM vendor that is used to by Gradle toolchains.
# You may want to build CAS using a Java version that is not supported for running Gradle
# by setting this property to the vendor of the JDK you want to use.
# Other options include: AMAZON, ADOPTIUM, JETBRAINS, MICROSOFT, ORACLE, SAP, BELLSOFT, etc.
jvmVendor=AMAZON

What it does is using the referenced vendor's toolchain, downloads it, and uses it for compilation. It DOES default to Correto, yes, but setting it to any other vendor toolchain that you might prefer for compilation, it should download it and use it. I've tried several (those JDKs that are not statically installed on my system) and it worked flawlessly. For example here's part of the build output for jvmVendor=LIBERICA

>./gradlew clean build

Here's more info on Gradle's toolchain auto-detection: https://docs.gradle.org/8.9/userguide/toolchains.html#sec:auto_detection

I don’t have that config in 7.0.x.

I haven’t started looking at 7.1.x yet.

Thank you Dmitriy. It works with jvmVendor=ORACLE (with a warning though):

# ./gradlew clean build
Starting a Gradle Daemon (subsequent builds will be faster)

Invalid Java installation found at '/root/.gradle/.tmp/jdks/openjdk-217603280809659208855.tmp' (provisioned toolchain) auto-detected auto-provisioned. It will be re-checked in the next build. This might have performance impact if it keeps failing. Run the 'javaToolchains' task for more details.
