Hello,

I am trying to install CAS 7.0 or 7.1 on Debian 12. I have installed Java 21 from the package provided here: https://download.oracle.com/java/21/latest/jdk-21_linux-x64_bin.deb

and Tomcat 10 from the Debian repository.

When I build, I get the following error:

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':bootWar'.
> Could not resolve all dependencies for configuration ':runtimeClasspath'.
> Failed to calculate the value of task ':compileJava' property 'javaCompiler'.
> Cannot find a Java installation on your machine matching this tasks requirements: {languageVersion=21, vendor=matching('AMAZON'), implementation=vendor-specific} for LINUX on x86_64.
> No matching toolchain could be found in the locally installed toolchains or the configured toolchain download repositories.

Did I use the wrong version of Java or tomcat?

Wouldsmina,

What do you get for

$ java -version

You could set JAVA_HOME to point to your jdk21 install location.

Hello Ray,

$ java --version

java 21.0.4 2024-07-16 LTS
Java(TM) SE Runtime Environment (build 21.0.4+8-LTS-274)
Java HotSpot(TM) 64-Bit Server VM (build 21.0.4+8-LTS-274, mixed mode, sharing)

I already set JAVA_HOME to /usr/lib/jvm/jdk-21.0.4-oracle-x64/

You have JRE. You need to install JDK (which includes javac compiler)

However, I have installed jdk from https://www.oracle.com/fr/java/technologies/downloads/#java21.

javac command exist :

# javac --version
javac 21.0.4

on my CAS server v6 in production (debian 11), the java --version command returns almost the same thing:
# java --version
openjdk 11.0.23 2024-04-16
OpenJDK Runtime Environment (build 11.0.23+9-post-Debian-1deb11u1)
OpenJDK 64-Bit Server VM (build 11.0.23+9-post-Debian-1deb11u1, mixed mode, sharing)

It seems like they add Amazon Corretto as a build requirement. I'm not sure why.

Emmett.
