Um mestre e um escravo do Jenkins 1.651 foram instalados em um Windows Server 2012. O escravo é dedicado a executar testes de selênio, mas na maioria das vezes ele fica off-line: 

Build step 'Execute Windows batch command' marked build as failure
ERROR: slave-tester is offline; cannot locate jdk7

Solução possível

Com base em source , parte do rastreamento de pilha: 

at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)
at java.util.concurrent.FutureTask.run(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

e experimentando o mesmo problema no escritório, atualizar o jdk7 para o mais recente oracle-jdk8 pode resolver o problema.

Se o problema persistir:

  1. Indique exatamente quando o problema ocorre para que seja possível reproduzir o problema
  2. Adicione o log de criação do Jenkins da versão que está causando o problema. Talvez exista uma tarefa específica executada pela tarefa que está causando o problema.
  3. Visualizar o gerenciador de tarefas do Windows durante a criação do trabalho
  4. Adicione o log de uma das compilações bem-sucedidas e o log de uma das compilações com falha
