What to install in advance

We recommend a 64-bit OS with a memory of 4GB or more. The OS can be Windows / macOS / Linux.

• JDK 11 --I think any build, such as Zulu or AdoptOpenJDK, will probably work, but I'm using the linked Oracle build OpenJDK. --Set the environment variables JAVA_HOME and PATH --Please set JDK 11 to IDE as well --IDE (one of the following two points)
  • IntelliJ IDEA --Ultimate Edition is recommended, but Community Edition is also OK -Eclipse 2018-09 version of Pleiades All in One --[Java]-[Standard Edition] is OK --Pleiades All in One is recommended for normal Eclipse and Spring Tool Suite because it is complicated to add JDK 11 related settings and plug-ins. --Please install the latest version of IDE. Older versions may not support JDK 11 or may not be able to run the tests written in JUnit 5. --Set the character code to UTF-8. --curl command (Exercise 6 only) --For Windows, select "Download WITHOUT SSL" from "CURL 7.xx.x" from http://www.paehl.com/open_source/ to download it, and set the environment variable PATH. --For macOS, it is installed by default. --jq command (Practice 6 only) --For Windows, download from https://stedolan.github.io/jq/download/, change the file name to "jq.exe", and set the environment variable PATH. --For macOS, you can install it with the Homebrew command brew install jq.

The database and application server use the built-in one (H2, Embedded Tomcat), so there is no need to install it.
