JVM系のソフトウェアをSDKMANで管理する
はじめに
不勉強なもので、JVM系の言語やツールを管理しやすくするSDKMANというツールの存在をつい最近知りました。 インストールやアップデート、複数のバージョンの切り替えなどをsdkというコマンドで扱えるようです。 この辺は悩みの種になりやすいところなので使ってみることにしました。
SDKMANインストール
$ curl -s "https://get.sdkman.io" | bash $ source "$HOME/.sdkman/bin/sdkman-init.sh" $ sdk version SDKMAN 5.7.4+362

Ant (1.10.1) https://ant.apache.org/
Apache Ant is a Java library and command-line tool whose mission is to drive
processes described in build files as targets and extension points dependent
upon each other. The main known usage of Ant is the build of Java applications.
Ant supplies a number of built-in tasks allowing to compile, assemble, test and
run Java applications. Ant can also be used effectively to build non Java
applications, for instance C or C++ applications. More generally, Ant can be
used to pilot any type of process which can be described in terms of targets and
tasks.
$ sdk install ant

AsciidoctorJ (2.1.0) http://asciidoctor.org/
AsciidoctorJ is the official library for running Asciidoctor on the JVM. Using
AsciidoctorJ, you can convert AsciiDoc content or analyze the structure of a
parsed AsciiDoc document from Java and other JVM languages.
$ sdk install asciidoctorj

13.0.1-openと12.0.2-openがインストールされていて、デフォルトが12.0.2-openになっていることが分かります。
$ java -version openjdk version "12.0.2" 2019-07-16 OpenJDK Runtime Environment (build 12.0.2+10) OpenJDK 64-Bit Server VM (build 12.0.2+10, mixed mode, sharing)
確かに12.0.2が使われます。これを13.0.1-openに切り替えてみます。
$ sdk default java 13.0.1-open Default java version set to 13.0.1-open $ java -version openjdk version "13.0.1" 2019-10-15 OpenJDK Runtime Environment (build 13.0.1+9) OpenJDK 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)
どのように管理されているのか？
このまま使うのは気持ち悪いので、各ソフトウェアがどういう風にインストールされているのかを確認してみます。
$ which java /home/myuser/.sdkman/candidates/java/current/bin/java
どうやらホームディレクトリの.sdkman以下にインストールされているようです。
ディレクトリとファイルの構成は以下の通り。
$ cd ~/.sdkman $ ls archives bin candidates etc ext src tmp var $ ls archives/ java-12.0.2-open.zip java-13.0.1-open.zip kotlin-1.3.61.zip scala-2.13.1.zip $ ls bin sdkman-init.sh $ find etc etc etc/config $ cat etc/config sdkman_auto_answer=false sdkman_auto_selfupdate=false sdkman_insecure_ssl=false sdkman_curl_connect_timeout=7 sdkman_curl_max_time=10 sdkman_beta_channel=false sdkman_debug_mode=false sdkman_colour_enable=true $ ls src sdkman-availability.sh sdkman-current.sh sdkman-flush.sh sdkman-list.sh sdkman-path-helpers.sh sdkman-update.sh sdkman-utils.sh sdkman-broadcast.sh sdkman-default.sh sdkman-help.sh sdkman-main.sh sdkman-selfupdate.sh sdkman-upgrade.sh sdkman-version.sh sdkman-cache.sh sdkman-env-helpers.sh sdkman-install.sh sdkman-offline.sh sdkman-uninstall.sh sdkman-use.sh $ find var var var/delay_upgrade var/broadcast_id var/version var/broadcast var/candidates $ cat var/version 5.7.4+362 $ cat var/candidates ant,asciidoctorj,bpipe,ceylon,crash,cuba,cxf,gaiden,glide,gradle,grails,groovy,groovyserv,infrastructor,java,jbake,kotlin,kscript,lazybones,leiningen,maven,micronaut,sbt,scala,spark,springboot,sshoogr,vertx,visualvm
管理対象のソフトウェアは.sdkman/candidatesの下にありました。
$ ls candidates/ java kotlin scala $ ls -l candidates/java 合計 8 drwxr-xr-x 8 myuser myuser 4096 12月 13 15:25 12.0.2-open drwxr-xr-x 8 myuser myuser 4096 12月 13 15:12 13.0.1-open lrwxrwxrwx 1 myuser myuser 48 12月 13 15:29 current -> /home/myuser/.sdkman/candidates/java/13.0.1-open $ ls -l candidates/kotlin 合計 4 drwxr-xr-x 5 myuser myuser 4096 11月 26 09:15 1.3.61 lrwxrwxrwx 1 myuser myuser 45 12月 13 15:22 current -> /home/myuser/.sdkman/candidates/kotlin/1.3.61 $ ls -l candidates/scala 合計 4 drwxrwxr-x 6 myuser myuser 4096 9月 18 18:23 2.13.1 lrwxrwxrwx 1 myuser myuser 44 12月 13 15:23 current -> /home/myuser/.sdkman/candidates/scala/2.13.1
ソフトウェアの種類ごとにディレクトリを分けてその下に複数のバージョンを展開し、シンボリックリンクでcurrentを示す、という割とシンプルな構成でした。
おわりに
言語処理系以外でも、ant、Maven、sbt等の周辺ツールもSDKMANで管理できます。仕組みもシンプルで使い勝手良さそうです。開発環境で活用していきたいと思います。
