ArduBlock のビルド

Last updated at Posted at 2017-05-25

20221113追記
今どきの環境にあわせたビルド方法を新たに書きました。
↓以下の記事です。

Ardublock を Docker でビルドする

https://qiita.com/nanbuwks/items/1a576859987e463264c3

Docker使わない場合でもリンク先の新しい記事のビルド方法をお使いいただくのがいいかと思います。

ArduBlock とは

Scratch ライクなブロックプログラムを Arduino で行うプログラム環境。
Arduino IDE のプラグインとして動作する。

準備

環境

  • Ubuntu 16.04 LTS (AMD64)
  • Ubuntu 20.04 LTS (AMD64)

ArduBlock のソースを取得

最近公式の更新が捗っているので現時点での最新版で試してみる

https://github.com/taweili/ardublock
よりパッケージをダウンロードして展開

 tar xzvf ardublock-beta-20170414.tar.gz 
 cd ardublock-beta-20170414/

必要なパッケージをインストール

openjdk

ここでいろいろ問題発生。結論から言うと、openjdk-8-jdk を使えば良い。openjdk-9-jdk をインストールするためにアレコレやったのは必要ありませんでした。

$ sudo apt install openjdk-8-jdk

(以下は無駄なことをやった記録)

sudo apt-get install openjdk-9-jdk

処理中にエラーが発生しました:
 /var/cache/apt/archives/openjdk-9-jdk_9~b114-0ubuntu1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

パッケージのミスかな?


  sudo dpkg --configure -a
  sudo dpkg -i --force-overwrite '/var/cache/apt/archives/openjdk-9-jdk_9~b114-0ubuntu1_amd64.deb'

これでクリア

maven


 sudo apt-get install maven

ああ、そうだった! openblocks が必要なのでした。

openblock のインストール

https://github.com/taweili/openblocks
からソースをダウンロード。適当なディレクトリで


  unzip openblocks-master.zip 
  cd openblocks-master/
  mvn install

ArduBlock

ArduBlock作業のディレクトリに戻って

エラーで止まる。

何年か前にビルドした時は


 mvn exec:java -Dexec.mainClass="com.ardublock.Main"

ではなく


 mvn compile exec:java -Dexec.mainClass="com.ardublock.Main"

とするとビルドできたのでこちらで試してみる。

$ mvn compile exec:java -Dexec.mainClass="com.ardublock.Main"

この対策として、

$ vim pom.xml

として


                        <plugin>
                                <groupId>org.apache.maven.plugins</groupId>
                                <artifactId>maven-compiler-plugin</artifactId>
                                <version>2.3.2</version>
                                <configuration>
                                        <source>1.5</source>
                                        <target>1.5</target>
                                </configuration>
                        </plugin>

↓書き換える


                        <plugin>
                                <groupId>org.apache.maven.plugins</groupId>
                                <artifactId>maven-compiler-plugin</artifactId>
                                <configuration>
                                        <source>1.6</source>
                                        <target>1.6</target>
                                </configuration>
                        </plugin>

(2022.02.24 に試したときには後述のエラーが出たため以下のようにしました。)

                                        <source>${java.version}</source>
                                        <target>${java.version}</target>

文字コードによるエラー

ここから、UTF-8にマップできない文字によるエラーの対処。
結局ここの作業は必要なかった。openjdk-9だとこのエラー出るがopenjdk-8を使うことになったので問題は解消。


mvn compile exec:java -Dexec.mainClass="com.ardublock.Main"

vim src/main/java/com/ardublock/translator/block/dfrobot/lcdkeypad.java

として下記部分のコメントを削除


        {
                // récupération des paramètres du module, ici le message placé en rang 0
                // on écrit donc le code à  générer

                // création du texte de code correspondant

この後、以下のように出るエラーを対処するために

中止 (コアダンプ)

エスケープされた文字をデコードするプログラムをワンライナーで対処したり、

for textfile in $( ls . | grep properties$ ); do  cat  "${textfile}"  | sed -e 's/\\u\(....\)/\&#x\1;/g' | nkf --numcha

( src/main/resources/com/ardublock/block でこれを実行 )
bg.DuinoEDU_infrared_compare.description を必要としているモジュールを読み込まないようにするためにskinをslimにしたり

 cd ./src/main/resources/com/ardublock/block/
 cp Skins/slim/* .

したが、コアダンプが発生するので openjdk-8 に変更した。

 mvn package

でjarファイルができるので、

Arduinoのスケッチなどを保存するディレクトリ( Ubuntuでは ~/Arduino/ )の ./tools/ArduBlockTool/tool

に /target/ardublock-all.jar をコピーする
