linux - Arch Linux ARMv7 - Maven を使用した Pi4J ビルドが JNI で失敗する

Question

Arch Linux ARM がインストールされた Raspberry Pi2 モデル B で Pi4J をビルドしようとしています。JNI 自然ライブラリのビルドを除いて、すべて正常に動作します。エラーメッセージ（およびログの一部）は次のとおりです。

考えられることはすべて試しましたが、うまくいきません。助けてください：）

編集：

さらに調査した結果、これらのメッセージが何を意味し、どのように機能するかについて考え始めています。これは、エラーが発生する build.xml の一部です。

            <!-- ensure the target directory is empty on the Raspberry Pi -->
            <sshexec host="${pi-host}" port="${pi-port}" username="${pi-user}"
                    password="${pi-password}" trust="true" failonerror="true"
                    verbose="true" command="rm --recursive --force ${pi-dirBuildTemp}" />

正確には、「verbose」で始まる行です。コマンドを編集して、その一部を削除しようとしました...何も役に立ちません。私はコードのブロック全体を削除しようとしましたが、他のブロック (それは本当にそのように見えます) を残して、エラーは次のブロックの最後の行にあります。/media/temp/pi4j-arch/pi4j-native/build.xml 全体は次のとおりです。

    </target>
</project>

コード自体に問題があるのではなく、sshexec コマンドに問題がある可能性があります。しかし、私はそれがどのように機能し、何が問題なのかをまだ理解していません。明日は、実験のために、変数を削除してそこに値を入れようとします。

EDIT2：テストしました...同じ場所で同じエラーが発生します...

誰かがアイデアを持っている場合は、共有してください。

EDIT3：

プルンジさん、ありがとうございました！今、私は数歩先を行っています！最初のものと同じように、あなたが提案したことの両方を行いました（しかし、試したときにSSHを再起動するのを忘れていたので、うまくいくかもしれません）。

今、別のステップで別のエラーが発生しました...グーグルで検索したときに1つの結果しか得られませんでしたが、彼らが話していたファイルが見つかりませんでした: https://github.com/rm-hull/wiringPi/issues/ 2 そして、これがまったく同じ問題であるかどうかはわかりません。

エラーは次のとおりです。

これがどのように機能するのか本当にわかりません。コメントに（build.xmlファイルに）書かれているものがどこにもありません...エラーの原因となっているbuild.xmlの部分は次のとおりです。

<!-- download and compile the 'wiringPi.a' native static library on the Raspberry
        Pi platform -->
<sshexec host="${pi-host}" port="${pi-port}" username="${pi-user}"
        password="${pi-password}" trust="true" failonerror="true"
        verbose="true" command="cd ${pi-dirBuildTemp};  sudo chmod +x wiringpi-build.sh; ./wiringpi-build.sh" />

私は、wiringpi-build.sh を見つけることができません ...

よろしくお願いします、クルム

SSH プロトコル経由で Pi と通信できません。

まだ行っていない場合は、無制限の強度の暗号化ポリシーファイルを、Maven を実行している JDK/JRE にインストールしてみてください。これにより、SSH 経由で接続するときに、より多くのアルゴリズムをネゴシエートできます。

別の方法は、Pi の SSHD 構成ファイルを変更して、JDK/JRE の JSCH がサポートするアルゴリズムを許可することです。これを行うための詳細は、この回答にあります。
