JDK-Selector

Select your JDK anywhere, anytime by single or two commands

This project is discontinued because...

It was my first project in Rust and kind of draft so codes didn't look clean, straightforward and cover edge cases at most times.

Moreover, I felt this project could be used in more places than where I expected.

Therefore, to expand concept of project I decided to create and maintain another well-designed project.

Check repo: https://github.com/Seungwoo-Yu/Package-Select

JDK-Selector still does the job well on Windows and Linux (Amd64 only though) and arm64 macOS.

This library provides you opportunity to change JDK version instantly by some commands.

Simple usage

1. Install JDK-Selector
2. (Re)open terminal
3. Type jdk_selector_cli add name path

   i.e jdk_selector_cli add "JDK 1.8" "C:\Program Files\Java\jdk1.8.0_321"
   

4. Type jdk_selector_cli use name

   i.e jdk_selector_cli use "JDK 1.8"
   

5. Done!

For details, please see jdk_selector_cli (help)

Build steps

1. Install rustup https://rustup.rs/
2. Clone this source

   git clone https://github.com/Seungwoo-Yu/JDK-Selector
   

3. Run cargo update in order to download dependencies

   cargo update
   

4. Build source

   cargo run --bin jdk_selector_builder
   

5. Check out .build folder in the source root!

Manual installation

1. Copy files into anywhere you want
2. Set JAVA_HOME Environment Variable to where you copy
   1. for Windows, See https://learn.microsoft.com/en-us/previous-versions/office/developer/sharepoint-2010/ee537574(v=office.14)#to-add-a-path-to-the-path-environment-variable
   2. for most Unix systems, See https://unix.stackexchange.com/a/26059 and keep in mind the sentence below,

   Put the line to modify PATH in ~/.profile, or in ~/.bash_profile or if that's what you have. (If your login shell is zsh and not bash, put it in ~/.zprofile instead.)
   

3. Append PATH Environment Variable with this

   %JAVA_HOME% // bin MUST be excluded!
   

4. Reopen terminal to affect changes
5. Type this to check if it's installed successfully!
