CloudSim Plus - Manual Build With CMD

This project provides a self-contained command-line based approach to build the whole cloudsimplus java library.

Key Points

• No build system. (no maven, no gradle)
• Only a single build.bat file is used to build the whole project.
• I just used javac and java (comes with JDK) to build the projects (cloudsimplus & cloudsimplus-examples) and run those examples.
• I vendored all dependencies (.jars) in the libs/ folder. Inside build.bat I generate the classpath using all the libraries in the libs/ folder. (cmd magic)
• java & javac version

javac --version
javac 21.0.5

 java --version
openjdk 21.0.5 2024-10-15 LTS
OpenJDK Runtime Environment Temurin-21.0.5+11 (build 21.0.5+11-LTS)
OpenJDK 64-Bit Server VM Temurin-21.0.5+11 (build 21.0.5+11-LTS, mixed mode, sharing)

• You can compile the project using atleast java-17.

Build

• Just run: build.bat. That's it.
• You can look what it's doing beforehand. (if you are not comfortable to run it directly).
• Let me know if you'd like a Linux version of the build system (.sh scripts). Actually it's super simple to convert build.bat to build.sh. This is the power of simplicity (I guess).

Run

• By default script will run the org.cloudsimplus.examples.BasicFirstExample.
• If you wants to run something else, modify build.bat (where I try to run example using java).

• src/: This directory contains the source code of whole cloudsimplus library.
• samples/: This contains all the source code of the cloudsimplus-examples.
• out/: This contains all generated .class files for cloudsimplus library. (not added to repo)
• out_samples/: This contains all generated .class files for cloudsimplus-examples. (not added to repo)
• lombok.config: Config file to be used by preprocessor i.e. lombok.
• libs/: This contains all the libraires (dependencies) to build this project. (literally 17 dependecies).

NOTE: dependencies are not good. If you are building a library, try to be as minimal and as bare bones as possible. (that would be best, at least for simple tasks don't use any other libraries).
