如何基于TeamCity Kotlin DSL中的现有步骤创建自定义构建步骤? [英] How to create custom build step based on existing one in TeamCity Kotlin DSL?

问题描述

我使用TeamCity Kotlin DSL 2018.1设置构建配置.我的settings.kts文件如下所示:

I use TeamCity Kotlin DSL 2018.1 to set up build configuration. My settings.kts file looks like this:

version = "2018.1"

project {
    buildType {
        id("some-id")
        name = "name"
        steps {
            ant {
                name = "Step1"
                targets = "target1"
                mode = antFile { path = "/some/path" }
                workingDir = "/some/dir"
                jdkHome = "some_jdk"
            }
            ant {
                name = "Step2"
                targets = "target2"
                mode = antFile { path = "/some/path" }
                workingDir = "/some/dir"
                jdkHome = "some_jdk"
            }
            ...
        }
    }
}

它可以按预期工作，但是我要避免为每一步重复编写相同的重复参数.

It works as expected, but I want to avoid writing the same repeating parameters for every step over and over again.

我尝试编写函数，该函数将构建预先填充有默认值的构建步骤:

I tried to write function, which would construct build step pre-filled with default values:

fun customAnt(init: AntBuildStep.() -> kotlin.Unit): AntBuildStep {
    val ant_file = AntBuildStep.Mode.AntFile()
    ant_file.path = "/some/path"

    val ant = AntBuildStep()
    ant.mode = ant_file
    ant.workingDir = "/some/dir"
    ant.jdkHome = "some_jdk"
    return ant
}
project {
    buildType {
        id("some-id")
        name = "name"
        steps {
            customAnt {
                name = "Step1"
                targets = "target1"
            }
            customAnt {
                name = "Step2"
                targets = "target2"
            }
            ...
        }
    }
}

它可以编译，但是不起作用:TeamCity只会忽略以这种方式定义的构建步骤.

It compiles but doesn't work: TeamCity just ignores build steps, defined in this way.

很遗憾，官方文档不包含任何信息关于定制和扩展DSL.可能是我在Kotlin的() -> Unit构造上做错了，但找不到确切的错误.

Unfortunately, official documentation doesn't contain any information about customizing and extending DSL. Probably, I'm doing something wrong with Kotlin's () -> Unit construction, but can't find out what exactly is wrong.

推荐答案

我明白了.

实际上，我很近.以下代码可以按我的意愿工作:

Actually, I was close. The following code works just as I wanted:

version = "2018.1"

fun BuildSteps.customAnt(init: AntBuildStep.() -> Unit): AntBuildStep {
    val ant_file = AntBuildStep.Mode.AntFile()
    ant_file.path = "/some/path"

    val result = AntBuildStep(init)
    result.mode = ant_file
    result.workingDir = "/some/dir"
    result.jdkHome = "some_jdk"
    step(result)
    return result
}

project {    
    buildType {
        steps {
            customAnt {
                name = "step1"
                targets = "target1"
            }
            customAnt {
                name = "step2"
                targets = "target2"
            }
            ...
        }
    }
}
