Jenkinsfile如何在并行分支中捕获多个异常

我有一个jenkins脚本，jenkins管道作业使用该脚本：

 try{
     parallel branch1: {
          //some function that may throw exception
     }, branch2: {
          //some function that may throw exception
     }, branch3: {
          //some function that may throw exception
     }
 }catch(Exception e){
     //Need to gather the error information together.
     //if there is only 1 error then that's it; 
     //if there are 2 or more errors then concatenate them or so, etc.. and print it. 
 }

---

如何获取这些分支中的所有异常？或者我就是做不到？

假设您能够以某种方式将错误捕获到变量中，捕获输出并将其存储到结束阶段。然后，您所要做的就是将每个阶段的构建结果设置为成功，以防止作业过早失败。请参阅以了解如何做到这一点。最后，在末尾连接变量

最终结果可能看起来像（半伪代码）

我甚至可能在尝试/捕获之外，仅仅依靠设置

currentBuild.result

s来处理错误

try{
    parallel branch1: {
         //some function that may throw exception
         error1=$(echo error)
         currentBuild.result = 'SUCCESS'
         return
    }, branch2: {
         //some function that may throw exception
         error2=$(echo error)
         currentBuild.result = 'SUCCESS'
         return
    }, branch3: {
         //some function that may throw exception
         error3=$(echo error)
         currentBuild.result = 'SUCCESS'
         return
    }
}catch(Exception e){
    //gather the error information together (if there 1 error then just it, if there are 2 errors then concatenate 2 errors together, etc) and print it. 
    print $error1 + $error2 + $error3
}
