SDKMAN!でOpenJDK 11をインストール
Installing Oracle OpenJDK 11 on Ubuntu でWSL上のUbuntuにOpenJDK 11をシステムワイドにインストールしたものの、やはりSDKMAN!で気軽にバージョンスイッチできるようにしたいと思い移行することにした。他の候補として jenv もあったが今回は一旦見送り。
Setup
インストールは以下のコマンドを実行するのみ。
code:sdkman
$ sudo apt install zip # zip コマンド必須
$ curl -s "https://get.sdkman.io" | bash
$ source "$HOME/.sdkman/bin/sdkman-init.sh"
SDKMAN!のインストールが完了すると、使用しているシェルに応じて以下のように追記される。
code:.bashrc
#THIS MUST BE AT THE END OF THE FILE FOR SDKMAN TO WORK!!!
export SDKMAN_DIR="/home/perforb/.sdkman"
-s "/home/perforb/.sdkman/bin/sdkman-init.sh" && source "/home/perforb/.sdkman/bin/sdkman-init.sh"
OpenJDK 11をインストールしてみる
code:sdk list
$ sdk list java

Use the Identifier for installation:
$ sdk install java 11.0.3.hs-adpt
================================================================================
code:sdk install
$ sdk install java 11.0.7-open
code:sdk use
$ sdk use java 11.0.7-open
code:before
$ java -version
openjdk version "11.0.7" 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mixed mode, sharing)

JAVA_HOMEはどうなるか
code:test
$ echo $JAVA_HOME
/home/perforb/.sdkman/candidates/java/current
このようにSDKMAN!でインストールしたJavaを向くようになる。
