上面提到的堆栈跟踪来自salve(Windows)机器，并且我的Jenkins/Master在RHEL上运行，我能够在其中看到以下堆栈跟踪.

Above mentioned stack trace is from salve (Windows) machine and my Jenkins/Master is running on RHEL, i am able to see following stacktrace there.

推荐答案

• 在更新我们的詹金斯大师之后，我发现了同样的错误.可能是由于Java 7(v80)与最新的Java 8不兼容.
• 检查主服务器正在使用的Java版本和从属服务器的Java版本.

• 就我而言，我在Linux主机上运行swarm-client-2.0-jar-with-dependencies.jar，它使用的是Java 7.

  • I observed the same error after our jenkins master was updated. It is likely due to incompatibility between Java 7 (v80) and latest Java 8.
  • Check the java version being used by your master, and the java version of your slave.

  • In my case, I am running swarm-client-2.0-jar-with-dependencies.jar on a linux host, and it was using Java 7.

    java版本"1.7.0_80" Java(TM)SE运行时环境(内部版本 1.7.0_80-b15)Java HotSpot(TM)64位服务器VM(内部版本24.80-b11，混合模式)

    java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

  • 我们的jenkins主服务器已升级，现在正在运行Java 8

  • Our jenkins master was upgraded and is now running Java 8

    java版本"1.8.0_121" Java™SE运行时环境(内部版本 1.8.0_121-b13)Java HotSpot(TM)64位服务器VM(内部版本25.121-b13，混合模式)

    java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

  • 将从属服务器上的Java更新为Java 8后，连接问题消失了.
