Installation

Feel free to support your own java journey with the solutions of this project. This project provides a dockerfile which contains a ready to use java environment. Just run the dockerfile and connect to the running container with VS Code.

Usage

The solutions are organized within packages and classes in the src folder of this project. The coding challenges are described within the classes itself or in markdown files named task.md within the packages.

Contributing

to contribute to the project, in order to report bugs or request additional solutions of coding challenges, feel free to open issues. if you would like to contribe with bug fixes or your own solution to challenges open a pull request and we will review your changes.

in order to run jdk 17 with maven you need compatible versions

add instructions based on this post from digitalocean to the dockerfile

Step 1: Download the Maven Binaries

wget https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz
tar -xvf apache-maven-3.8.6-bin.tar.gz
mv apache-maven-3.8.6 /opt/

Step 2: Setting M2_HOME and Path Variables

M2_HOME='/opt/apache-maven-3.8.6'
PATH="$M2_HOME/bin:$PATH"
export PATH

Step 3: Verify the Maven installation

mvn -version
