How do you structure the process of dependency installation and compilation within a single layer of the system?

To structure the process of dependency installation and compilation within a single system layer, the following approaches are usually used:

• Using package managers (e.g., Maven, Gradle for Java, npm for JavaScript), which automatically resolve and install dependencies.
• Defining a clear configuration file (pom.xml, build.gradle, etc.) where all dependencies and build settings are described.
• Dividing the process into stages: first installing and verifying dependencies, then compiling the source code.
• Automating through scripts or CI/CD pipelines to ensure repeatability and consistency of the build.

Example for Java with Maven:

<project>
  <dependencies>
    <dependency>
      <groupId>org.example</groupId>
      <artifactId>library</artifactId>
      <version>1.0.0</version>
    </dependency>
  </dependencies>
</project>

The command mvn clean install will first download all dependencies, then compile the project.
