Open GDS gradle build fails since 2.14.0

[JohT]

Describe the bug

❌ When I try to build the open GDS version with
./gradlew -Dorg.gradle.logging.level=info "-Dorg.gradle.jvmargs=-Xmx2g" -Pneo4jVersion=5.26.2 --stacktrace -- :open-packaging:shadowCopy, I get the following build error (log file) pointing to gradle/dependencies.gradle:

Script '/home/runner/work/open-graph-data-science-packaging/open-graph-data-science-packaging/gradle/dependencies.gradle' line: 1
...
Caused by: groovy.lang.MissingPropertyException: Could not get unknown property 'reposityRootDirectory' for root project 'open-gds' of type org.gradle.api.Project.

✅ There were no issues in the previous version 2.13.2.
🤔 Could this be a typo ($repositoryRootDirectory instead of $reposityRootDirectory)?
🤔 Additionally, neo4j-version.gradle seems to be missing. Is this a typo as well?

To Reproduce

• GDS version: 2.14.0
• Neo4j version: 5.26.2
• Operating system: Ubuntu 24.04.1
• Example pull request with failing pipeline: Update dependency neo4j/graph-data-science to v2.16.0 JohT/open-graph-data-science-packaging#63

Hello @JohT, thank you for reporting this, we have been restructuring our builds and it seems this has been an oversight at our end, we will look into it and we'll let you know once we have the builds fixed.

@vnickolov, the described issue seems to have been resolved with v2.16.0.

However, now I get the error message below. It seems that neo4j already uses Java 21 features even though it should be compatible with Java 17 according to the documentation. It doesn't seem to be a problem of graph-data-science and I'm fine with migrating to Java 21 so I'd be fine with closing this issue.
