Question

我尝试构建html格式的字符串，以通过jenkins管道将其作为电子邮件发送。我有以下代码：

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def html = new MarkupBuilder( writer )

html.table( class: "squishSummary" ) {
    style( type: "text/css" ) {
        mkp.yield( getTableStyle() )
    }
    ...
}

def getTableStyle() {
    ....
}

不幸的是，这在执行管道时遇到错误：java.lang.NoSuchMethodError: No such DSL method 'style' found among steps [...]如果我正确地理解它，那么jenkins服务器尝试将样式命令作为jenkins构建步骤来执行，那么合理的失败。我该如何解决？

以下代码可以正常工作：

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def html = new MarkupBuilder( writer )

html.table( class: "squishSummary" ) {
    style( type: "text/css" ) {
        mkp.yield("123")
    }
}
println writer

但是，如果您声明名为style的变量，则会得到与您类似的错误

所以此代码将失败，并显示groovy.lang.MissingMethodException: No signature of method ...

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def html = new MarkupBuilder( writer )

def style = "my style1" //just add this line and code fails

html.table( class: "squishSummary" ) {
    style( type: "text/css" ) {
        mkp.yield("123")
    }
}

println writer

要解决问题，请使用delegate或GString而不是简单的方法名称：

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def html = new MarkupBuilder( writer )

def style = "style1"

html.table( class: "squishSummary" ) {
    delegate.style( type: "text/css" ) {
        mkp.yield("123")
    }
    //or like this:
    "${'style'}"( type: "text/css" ) {
        mkp.yield("123")
    }
}

println writer

没有这样的DLS方法“样式”（MarkupBuilder）
