Git If-else语句在Jenkins管道脚本（groovy）中工作不正常

我有一个管道脚本（groovy），我试图使用if和else条件，但它的行为并不正常。似乎它总是返回false

以下是我的示例（剪贴）管道脚本：

def branch_exists_in_node = 1
def branch_exists_in_common = 0
def branch_exists_in_extra = 0
                if(branch_exists_in_node == 1) {
                    NODE_BRANCH = env.BRANCH_NAME
                }else {
                    NODE_BRANCH = "master";
                }
                if(branch_exists_in_common == 1) {
                    COMMON_BRANCH = env.BRANCH_NAME
                }else {
                    COMMON_BRANCH = "master"
                }

但在这里，即使值为1，它也总是求值为false。语法有问题吗

当我对上述变量进行回显时，它打印得很好

                    echo "${branch_exists_in_angular}" //0
                    echo "${branch_exists_in_node}" //1
                    echo "${branch_exists_in_common}" //0

更新： 这是我的最小jenkins管道脚本，请帮助

        }
    }
}

请记住

sh（returnStdout:true，script:…）

返回

String

因此

branch\u等变量存在于\u angular

中是字符串而不是数字。在Groovy（包括Jenkins Groovy CPS环境）中，以下表达式的计算结果总是

true

：

if ('0') {
    echo "0 is 0"
}

if ('1') {
    echo "1 is 1"
}

使用

（expr）作为整数将
sh
步骤的结果强制转换为整数

：

branch_exists_in_angular = sh(script: 'git ls-remote --heads $ANGULAR_REPO $EXTRA_BRANCH | wc -l', returnStdout: true) as Integer

---

它将使您的变量成为

整数类型

，然后

if（0）

将计算为

false

，

if（1）

将计算为

true

，

请显示完整值。您的变量可能在当前范围之外或类似的范围之外定义。确定。给我一个minute@SzymonStepniak我已经添加了代码…请检查哇，你救了我一天。。。从早上开始就在挣扎。多谢各位
