现有Groovy代码 #

def updateProjectPackage(params) {
    packageFile = readJSON(file: 'package.json')
    //params.appVersion = 0.0.0-alpha.0
    packageFile.version = params.appVersion
    writeJSON file: packageFile
}

原始package.json内容 #

{
  "name": "demo",
  "version": "0.1.0"
}

解决方案 #

错误原因 #

调用writeJSON时参数传错：writeJSON的file参数需要接收文件路径字符串，但你把读取到的JSON对象（packageFile）传给了file参数，导致Jenkins无法解析参数类型，抛出异常。

修正后的代码 #

def updateProjectPackage(params) {
    def packageFile = readJSON(file: 'package.json')
    packageFile.version = params.appVersion
    // 正确传入参数：file指定路径，json指定要写入的对象，可选pretty参数格式化输出
    writeJSON file: 'package.json', json: packageFile, pretty: 2
}

说明 #

• file: 'package.json'：指定要写入的文件路径
• json: packageFile：指定要写入的JSON对象
• pretty: 2：可选参数，让生成的JSON文件带缩进，提升可读性
