Jenkins 具有平行级的詹金斯管道“原因”；这一过程显然从未开始”；错误

我试图建立一个Jenkins管道（使用声明性语法），在两个独立的、按需的AWSEC2实例上运行单元测试和功能测试。当在单个实例上运行并且没有并行阶段时，管道可以完美地工作。一旦切换到并行阶段，任何shell脚本都会失败，并显示以下神秘消息：

这一过程显然从未在年开始 /home/admin/workspace/GSWebRuby_Test@tmp/耐用-b0d8c4b4（运行 詹金斯暂时和我在一起 -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH\u DIAGNOSTICS=true （可能会让问题更清楚）

我在谷歌上搜索了很多地方，发现了一些关于这条消息的bug报告。我正在使用最新版本的插件v。1.33并且所有问题似乎都不适用于我的情况，例如，在不寻常的体系结构上或在运行Docker容器时出现故障。我还关闭并重新升级了插件（在版本1.30和1.33之间切换）。另外，为了重新迭代，

sh

命令在我不使用

并行

阶段时可以正常工作

我已经创建了一个简化的管道来调试这个问题。请注意，shell命令也很简单，例如“env | sort”或“pwd”

这是控制台输出：

我在设置管道的过程中是否做错了什么？任何指点都将不胜感激

编辑：

设置此

JENKINS\u JAVA\u选项后

org.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH\u DIAGNOSTICS=true

，我看到了以下额外输出：
