Task Tracker CLI

A command-line task tracking application built as part of my Java learning journey following the roadmap.sh path. This project demonstrates practical implementation of modern Java features while helping others learn through real-world examples.

About This Project

This Task Tracker is a practical exercise in building command-line applications using Java, focusing on modern language features and clean code practices. It's part of a series of projects aimed at improving Java skills through hands-on experience.

Key Technologies & Concepts Used

• Modern Java Features

  • Records for immutable data structures
  • Stream API for data processing
  • Local variable type inference (var)
  • Pattern Matching (Java 17+)

• Libraries

  • Jackson for JSON file handling
    • JSON reading/writing
    • Object mapping
    • Data persistence

• Project Purpose

  • Practice modern Java features
  • Learn file handling and data persistence
  • Implement CLI interfaces
  • Apply clean code principles

Learning Outcomes

Through this project, I practiced:

• Building interactive CLI applications
• Working with file systems using Java
• Data persistence using JSON
• Modern Java features in a real-world context
• Command pattern implementation

Installation

Detailed instructions for installing and running the Task Tracker CLI are available in the Getting Started section below.

Getting Started

1. Ensure you have Java 17+ installed
2. Clone the repository
3. Build the project using Maven
4. Add to your system's PATH for easy access

Example:

# 1. Create bin directory if it doesn't exist
mkdir -p ~/bin

# 2. Create the executable script
nano ~/bin/task-tracker

# In the script, add:
#!/bin/bash
# If your project is on Linux:
java -jar /path/to/your/project/target/task-tracker-cli-1.0-SNAPSHOT.jar "$@"

# In my case, since the project is on Windows but I'm using it through WSL:
java -jar /mnt/c/Users/example/Desktop/task-tracker-cli/target/task-tracker-cli-1.0-SNAPSHOT.jar "$@"

Important Note:

The /mnt/c/... path is specific for accessing Windows files from WSL If your project is directly on Linux, use the standard Linux path like /home/user/projects/... or ~/projects/... Make sure the path points to the JAR file generated in your project's target directory

# 3. Make the script executable
chmod +x ~/bin/task-tracker

# 4. Add bin to PATH in .zshrc
nano ~/.zshrc
export PATH="$HOME/bin:$PATH"

# 5. Reload the configuration
source ~/.zshrc
This method allows you to have your project on Windows, compile it there, but execute it conveniently from WSL as a regular command.
