与字符串比较在詹金斯管道中不起作用 [英] Comparison with string doesn't work in Jenkins pipeline

问题描述

任何下面的IF-ELSE起作用的想法

Any idea why the IF-ELSE below works

def checkPrValidity() {
    wordCountStr = sh returnStdout: true, script: 'git diff --ignore-space-at-eol $target_branch..PRbranch src | wc -l' 
    wordCount = wordCountStr.toInteger() //force conversion to int data type 
    if (wordCount == 0) {
        return false;
    } else {
        println("This is a valid PR, continue the job execution")
        return true;
    }
}

而以下一个则不

def checkPrValidity() {
    wordCountStr = sh returnStdout: true, script: 'git diff --ignore-space-at-eol $target_branch..PRbranch src | wc -l'
    if (wordCountStr == '0') {
        return false;
    } else {
        println("This is a valid PR, continue the job execution")
        return true;
    }
}

为什么我需要专门将string转换为Integer，而无法将其与string数据类型进行比较?

Why do i need to specifically convert a string to Integer, while it fails to compare it as a string data type?

推荐答案

尝试将.trim()添加到您的sh中.因为在输出中可以有换行，这会阻止正确比较.

Try to add .trim() to your sh. Because in output there can be new line, which prevents correct comparison.
