- Update the authentication mechanism to follow the current version of
the doc
- Added logs for common HTTP headers errors
- Added checks and a Builder, and ran spotless, to follow the usual
project's guidelines
- Updated to the newer (102) id for the JavaScript language

## Change
- Added `maven-flatten-plugin` to `langchain4j-parent` and
`langchain4j-bom`
- Removed integration-specific dependencies from `langchain4j-parent`'s
`dependencyManagement` section and moved them to the modules where these
dependencies are used
- Explicitly added missing implicit dependencies
- Removed redundant `<maven.compiler.release>` for cassandra, infinispan
and opensearch modules
- Removed redundant license declarations and outdated properties
## General checklist
- [ ] There are no breaking changes
- [ ] I have added unit and/or integration tests for my change
- [ ] The tests cover both positive and negative cases

## Issue
Cleanup repeating dependencies in pom.xml. Better test assertions and
apidocs/javadoc generation.
## Change
Refactor project structure and remove unused test dependencies.
- Repeating test dependencies like `tinylog`, `awaitility` and others
were removed from various modules and consolidated in the parent module.
This reduction in clutter helps to streamline the testing process.
- A separate `kotlin` profile was created to manage Kotlin-related
configurations and dependencies.
- Upgraded versions of dependencies like `ai-mocks` and `wiremock` were
implemented. Moved to wiremock-standalone (shaded jar) to avoid
potential version conflicts with runtime classes.
- The test changes in `ChatRequestExtensionsTest.kt` partially migrated
from AssertJ to Kotest assertions.
- Updated Dokka plugin configuration

## Change
This pull request includes the following changes to improve project
dependency management:
- Removed unnecessary and redundant Netty dependencies and exclusions.
- Updated and reorganized dependency versions for consistency, including
new BOM imports for Azure SDK, Netty, and Reactor.
- Eliminated AWS SDK v1 dependencies, transitioning to
`software.amazon.awssdk` BOM for better compatibility and reduced
clutter.
- Removed redundant test dependencies like `assertj-core` and `mockito`
across modules, referring to the parent POM.
- Adjusted `kotlinx-coroutines-test` to use JVM-specific artifact and
standardized dependency version variables.
- Refined POM XML formatting for consistency and clarity (`mvn
spotless:apply`)

## Change
This pull request includes changes to remove unnecessary dependency
conflict resolution comments and to simplify dependency management
across multiple `pom.xml` files. The most important changes include

dependency management.
Dependency conflict resolution removal:
* Removed comments related to `okhttp` dependency conflict resolution in
`code-execution-engines/langchain4j-code-execution-engine-judge0/pom.xml`.
* Removed comments related to `okhttp` dependency conflict resolution in
`langchain4j-chroma/pom.xml`.
* Removed comments related to `okhttp` dependency conflict resolution in
`langchain4j-cohere/pom.xml`.
* Removed comments related to `okhttp` dependency conflict resolution in
`langchain4j-hugging-face/pom.xml`.
* Removed comments related to `okhttp` dependency conflict resolution in
`langchain4j-mistral-ai/pom.xml`.

## Issue
Adds format consistency check for changed files. Closes#2109
## Change
- Add [Spotless Maven plugin](https://github.com/diffplug/spotless) for
code java (eclipse java format) and pom.xml formatting
- Added the `<project.root.dir>` property across multiple POM files to
standardize the directory structure reference. This ensures consistent
project configurations and reduces redundancy in defining the root
project directory. Adjusted existing XML formatting minimally to
accommodate the new property integration.
- Cleanup duplicate settings in pgvector module
- Updated pom.xml files were reformatted according to
[defaults](https://github.com/diffplug/spotless/tree/main/plugin-maven#sortpom)
+ 4 spaces
- Adding linting and formatting commands to the `Makefile`, updating the
`pom.xml` files for better project configuration, and enhancing the
`CONTRIBUTING.md` guidelines.

## Issue #1897
Dependency upgrade before #1897
## Change
- Use Kotlin BOM for dependency resolution
- Remove explicit Kotlin dependencies from multiple modules
This eliminates redundant Kotlin standard library dependencies across
various `pom.xml` files. The change resolves potential conflicts and
reduces unnecessary dependency overhead.
* Updated Milvus SDK to version 2.4.2

## Issue
Dependency cycles removed:
[langchain4j-core]->[langchain4j-parent]->[langchain4j-core]
This cycles prevented project fresh project correctly in Jetbrains Idea.
Cyclyc dependency between this repo and [langchain-embeddings
repo](https://github.com/langchain4j/langchain4j-embeddings) should be
fixed separately.
## Change
- Removed dependency cycles: Removed dependencies to project modules
from `langchain4j-parent`/dependencyManagement to avoid cycles. Added
explicit version number for
langchain4j-core,langchain4j,langchain4j-open-ai.
- Introduced `langchain4j-embeddings.version` for explicit dependency on
another repo.
- Added BOM dependencies to parent pom: junit-bom, mockito-bom. Remved
dependencies, defined in BOMs
- junit.version -> 5.11.3
- Upgraded maven-surefire-plugin, maven-failsafe-plugin. **NB! Renovate
bot is needed to do this automatically**

## Note
Please note that [issue ](https://github.com/square/okhttp/issues/8288)
for this was already created in `httpok` repository but it will not be
fixed in 4.x. It's reportedly already tackled in version 5.x.
With that in mind I suggest we apply temporary changes proposed in this
PR. After upgrading to `httpok` 5.x we will be able to remove these.
## Tests
`mvn clean test` passed
