Question

我写了一个与jeknins一起工作的管道，但作为jenkins脚本的新手，我有很多我不清楚的东西，这是整个脚本，我将表达下面的问题

SCRIPT：

    node()

    def libName = "PROJECT"
    def slnPath = pwd();
    def slnName = "${slnPath}\\${libName}.sln"

    {
    bat("svn upgrade");
    bat("svn info \"${slnPath}\" >revision.txt");

        for (String i : readFile('revision.txt').split("\r?\n"))
        {
            if(i.contains("Last Changed Rev: "))
            {
                def splitted = i.split(": ")

                echo "Revisione : "+ splitted[1];

    }

    {
        if (profile != "")
        {
            def buildProfile = profile.split(',');

        def stepsForParallel = buildProfile.collectEntries {
            ["echoing ${it}" : performTransformation(it,filenameBase,buildRevision)]

        }

        parallel stepsForParallel;

一系列问题是：

我看过一些脚本，其中所有内容都包含在管道{}中，这是必要的还是Jenkins管道插件会粘贴它？
我真的不喜欢在节点中包含所有这些定义，然后在下面复制。
我没有在Jenkins工作流内部看到并行性，即使我有4个执行器处于空闲状态。
我无法调用post管道事件来清除工作区（现在是rigth，它只是en echo

有两种类型的管道。像你所写的直接groovy被称为脚本管道。围绕它的pipeline{}块的样式是声明性样式管道。对于较新的Pipeline用户来说，声明性更容易，并且是开始使用管道的好选择。许多管道都不需要脚本允许的复杂性。
这很时髦。如果你想声明一堆变量，你必须在某个地方做。否则，您会在脚本中的某些位置对这些值进行硬编码。在groovy中，你不必声明每个变量，但你必须在某个地方定义它，除非你知道声明将如何影响范围，否则你应该声明它们。大多数编程语言都需要某种变量声明，特别是当你不得不担心范围时，所以我不知道这是一个问题。我认为在顶部的一个地方定义所有变量值是非常干净的。更易于维护。
乍一看，你的并行执行看起来应该可行，但除非我设置并运行它，否则很难说。可能是并行部分运行得足够快以至于UI没有更新。您应该能够在控制台输出中看到它们是否并行运行。
post管道块在脚本管道中不可用。这是声明性管道语法的一部分。在脚本中，要做类似的事情，你必须使用try / catch来捕获错误并运行post-type的东西。
