The story when I was using IntelliJ on Linux and could not input Japanese



Ubuntu Linux 18.04 LTS。

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.3 LTS
Release:	18.04
Codename:	bionic

IntelliJ version.

Event and solution

The event that was happening is the same as TL; DR. I was in trouble because I couldn't switch to Japanese input.

IME uses Mozc.

After a little research, I found the following article, so I switched Java used to start IntelliJ and tried it.

Problems and workarounds that occur while inputting Japanese in macOS environment with IntelliJ IDEA 2019.2 etc.

Click here for Java bundled with IntelliJ (used for startup by default).

jbr/bin/java --version
openjdk 11.0.5 2019-10-15
OpenJDK Runtime Environment (build 11.0.5+10-b520.17)
OpenJDK 64-Bit Server VM (build 11.0.5+10-b520.17, mixed mode)

Look at the following document and select the method to set with environment variables this time.

Change boot Java runtime for IntelliJ IDEA

Change the boot Java runtime of IntelliJ IDEA

Changed to start with OpenJDK 8.

$ IDEA_JDK=/usr/lib/jvm/java-1.8.0-openjdk-amd64

This time, this is the solution.
