How to: install Java

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. For this project, you need Java in order to use the serverless-dynamodb-local plugin, which is a local version of DynamoDB.

Prerequisites:

1. macOS: This is the only platform this project supports
2. Homebrew: a package manager for macOS

Steps:

1. Install java (openjdk v11):

   brew install java11
   

2. Add jdk to path:

   echo '; export PATH="/usr/local/opt/openjdk/bin:$PATH"' >> ~/.bash_profile
   

3. Link java:

   brew link --force openjdk@11
   

4. Re-init bash profile:

   source ~./.bash_profile
   

5. Run java --version to verify install.

   • should print version and runtime info to terminal, eg:

     openjdk 11.0.10 2021-01-19
     OpenJDK Runtime Environment (build 11.0.10+9)
     OpenJDK 64-Bit Server VM (build 11.0.10+9, mixed mode)
