Environment setup for Java Software Development on a MacOS

Java-Software-Development-setup-on-a-mac

Either follow this simple guide here or leverage other heavily oppinionated guides that are more comprehensive and community supported

# Option 1: Community support versions

First follow [xmlking's complete Mac setup](https://xmlking.gitbook.io/macos-setup/applications/sublime-text)

- General mac setup
- System preparedness and preferences - folders setup etc
- Application installations

There is another guide [here @sourabhbajaj](https://sourabhbajaj.com/mac-setup/SublimeText/Preferences.html) 
to check reference for additional configurations

## What I do in addition

Download
- Docker desktop: https://www.docker.com/products/docker-desktop/
- Google Chrome
- Office 365 apps: https://portal.office.com/account#






# Option 2: Keep it simple


## Homebrew

- Brew [installation](https://docs.brew.sh/Installation.html)
- Install cask `brew tap caskroom/cask`

### The bunch
    
    brew install \
    python \
    tree \
    cask \
    wget \
    bash-completion \
    git \
    watch \
    htop \
    tldr \
    jq \
    ncdu \
    zsh \
    speedtest-cli \
    midnight-commander \
    firefox \
    node \
    
    
    sudo easy_install pip
    xcode-select --install
    brew cask install iterm2
    # brew install docker -- favour the official install instead: https://docs.docker.com/docker-for-mac/install/

### Cask installs

First, fetch the latest version of homebrew and formula. Then tap the Caskroom/Cask repository from Github. After that search for the <package> and then install

    brew update
    brew tap homebrew/cask
    
    brew search visual-studio-code
    brew install visual-studio-code
    brew cask install sublime-text
    
    
## [Oh My Zsh!]

(Official site here)(https://ohmyz.sh/#install).  
Whiilst on it remember to install [the poweline fonts](https://github.com/powerline/fonts) for the advance zsh themese like Agnostic to work well.  This would install my favourite font: SourceCodePro


    sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
    
### Apply Theme

    ZSH_THEME="fino-time"
    
### Apply plugins
  
    plugins=(
      git
      git-extras
      gradle
      history
      helm
      iterm2
      sublime
      jenv
      kubectl
      man
      mvn
      nvm
      postgres
      python
      docker
      docker-compose
      docker-machine
      brew
      cask
      cp
      gcloud
      sudo
      yarn
    )

### Example usage:

- speedtest-cli --simple --bytes
- lunch midnight commander with `mc`

## Java

### Official download

[Oracle Java archive](https://www.oracle.com/technetwork/java/javase/archive-139210.html)


### Installing Java using Homebrew

Since the addition of a [Openjdk formulae](https://discourse.brew.sh/t/how-to-install-openjdk-with-brew/712/24),
all you now need is below making brew cask ... unneccessary:

    brew install openjdk # or
    brew install openjdk@11 # <--Specify version like so
    
    Then following the instructions from the output on completion e.g:
    
    For the system Java wrappers to find this JDK, symlink it with
      sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

### Configure Jenv

    
    jenv add /Library/Java/JavaVirtualMachines/openjdk.jdk/Contents/Home #adds latest version
    jenv add /usr/local/Cellar/openjdk@11/11.0.9/
    
    jenv global 11.0.9 # Sets default version
    cat ~/.jenv/version # verify global files is written
    jenv versions # verify versions

#### Deprecated/alternative means

    brew cask install java # Auto install the latest Oracle JDK
    brew cask info java # Verify latest version for auto installation
    
    brew cask install java8 # installs a specific version
 
### To install the JDKs from AdoptOpenJDK:

    brew tap adoptopenjdk/openjdk
    brew cask install adoptopenjdk8
    brew cask install adoptopenjdk9
    brew cask install adoptopenjdk10
    brew cask install adoptopenjdk11

### Add new version to Jenv

1. Check versions `jenv versions`
1. Add `jenv add /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home`

[Jenv for more](https://www.jenv.be)
