## Issue
Fixes#1909, Fixes#1899, Closes#1652
This pull request includes several updates to the GitHub Actions
workflows and Maven configuration files to modernize the Java version
and improve the build process. The most important changes include
upgrading the Java version, modifying the Maven build commands, and
updating dependencies.
## Change
- ⬆️ Min JDK version has been upgraded to 17
- 🗿 Hardening: run `mvn process-test-classes javadocs:aggregate` on
**ALL** modules to verify that code compiles before running integraiton
tests
- 💄 Reformat maven commands to multiline to fit on a screen
- Rename GoogleAiGeminiTokenizerTest to GoogleAiGeminiTokenizerIT
- Upgrade graalvm and Oracle image
- Run tests on every build, run integraiton tests only on
langchain4j/langchain4j repo

## General checklist
<!-- Please double-check the following points and mark them like this:
[X] -->
- [x] There are no breaking changes
- [ ] I have added unit and integration tests for my change
- [ ] I have manually run all the unit and integration tests in the
module I have added/changed, and they are all green
- [x] I have manually run all the unit and integration tests in the
[core](https://github.com/langchain4j/langchain4j/tree/main/langchain4j-core)
and
[main](https://github.com/langchain4j/langchain4j/tree/main/langchain4j)
modules, and they are all green
- [ ] I have added/updated the
[documentation](https://github.com/langchain4j/langchain4j/tree/main/docs/docs)
- [ ] I have added an example in the [examples
repo](https://github.com/langchain4j/langchain4j-examples) (only for
"big" features)
- [ ] I have added/updated [Spring Boot
starter(s)](https://github.com/langchain4j/langchain4j-spring) (if
applicable)
## Issue
#1506
## Change
Enabled Maven Enforcer Plugin on modules without existing version
conflicts to ensure they remain conflict-free. The Maven Enforcer Plugin
will now cause the build to fail if new conflicts are introduced
guarding against these.
## Tests
`mvn clean test` passed
with such a setting, you can safely build only once the whole project
with JDK 17 or even 21 without fearing any wrong API being injected in
.class files
