Fully hand-held tutorial on setting up the Java environment to a usable state as quickly as possible. Only knowledge of using the terminal is expected. This tutorial will be completely self-contained (excluding links to downloads).

...

• Download the latest Gradle 7 distribution (7.4.2 as of writing).
  • Choose the "complete" version.
  • Remember where you downloaded it.

• Unpack Gradle (the following are excerpted from the gradle website)

  • Open a terminal

  • cd into the directory where you downloaded Gradle. Then

• Excerpt
  Unzip the distribution zip file in the directory of your choosing, e.g.: Code Block $ sudo mkdir /opt/gradle $ sudo unzip -d /opt/gradle gradle-7.4.2-all.zip

• Add to path

  Code Block
  $ echo 'export PATH=$PATH:/opt/gradle/gradle-7.4.2/bin' >> ~/.bashrc

  
  

  
  

• Verify installation

  Excerpt
  Open a console (or a Windows command prompt) and run gradle -v to run gradle and display the version, e.g.: Code Block $ gradle -v ------------------------------------------------------------ Gradle 7.4.2 ------------------------------------------------------------

• Configure for IHMC software
  • excerpt from Gradle#Installation
  • create a gradle.properties file in your user Home directory, ~/.gradle/gradle.properties

  • Copy/paste below into the file

    Code Block
    org.gradle.java.home=TODO/usr/lib/jvm/java-17-openjdk-amd64 org.gradle.jvmargs=-Xmx4g

• Download IntelliJ Community. 
  • https://www.jetbrains.com/idea/download/#section=linux
  • Open a terminal and cd into the folder where you downloaded the tar file

  • Extract the file and move it to /opt/ (reference excerpt)

    Code Block
    $ tar -xzf ideaIC-2021.3.2.tar.gz $ sudo mv idea-IC-213.6777.52/ /opt/. $ ln -s /opt/idea-IC-213.6777.52/ /opt/idea $ sudo ln -s /opt/idea/bin/idea.sh /usr/local/bin/idea

  • Intellij is now installed and runnable from the command line 

    Code Block
    $ idea

  • To create a desktop entry, open IntelliJ once and select Tools > Create Desktop Entry

  •
