今日はやたらyak shavingした日なのでブログに残しておこう。( TДT)
いつの間にかLinux Slaveが起動しなくなってた
Jenkinsの画面からノードを選択して手動で起動してみる
[06/29/17 19:31:05] [SSH] スレーブのプロセスを開始: cd "/home/jenkins" && java -jar slave.jar
<===[JENKINS REMOTING CAPACITY]===>channel started
Slave JVM has not reported exit code. Is it still running?

あらら？
Slave JVM has not reported exit code. Is it still running? をぐぐってみるとどうやらJavaのバージョンに依存するエラーらしい。今まではJava7で動いていたのがだめになったんだろうか・・・
Java8にあげてみる
ubuntu 14.04なのでPPAで入れることにしました。
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:webupd8team/ppa
Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK7 / JDK8 / JDK9). There are no actual Java files in this PPA.
Important -> Why Oracle Java 7 And 6 Installers No Longer Work: http://www.webupd8.org/2017/06/why-oracle-java-7-and-6-installers-no.html
More info (and Ubuntu installation instructions):
- for Oracle Java 7: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
- for Oracle Java 8: http://www.webupd8.org/2012/09/install-oracle-java-8-in-ubuntu-via-ppa.html
Debian installation instructions:
- Oracle Java 7: http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html
- Oracle Java 8: http://www.webupd8.org/2014/03/how-to-install-oracle-java-8-in-debian.html
Oracle Java 9 (for both Ubuntu and Debian): http://www.webupd8.org/2015/02/install-oracle-java-9-in-ubuntu-linux.html
For JDK9, the PPA uses standard builds from: http://jdk.java.net/9/ (and not the Jigsaw builds!).
Important!!! For now, you should continue to use Java 8 because Oracle Java 9 is available as an early access release! You should only use Oracle Java 9 if you explicitly need it, because it may contain bugs and it might not include the latest security patches! Also, some Java options were removed in JDK9, so you may encounter issues with various Java apps. More information and installation instructions (Ubuntu / Linux Mint / Debian): http://www.webupd8.org/2015/02/install-oracle-java-9-in-ubuntu-linux.html

相変わらずプロキシ環境下で鍵をインストールするところで失敗する・・・。
