Jenkins-pipeline 从 groovy 中的属性文件中提取和设置变量

问题描述

首先，我将管道完全编写为 groovy，以便签入到 git.请不要提供任何 gui 必要的解决方案.我的问题陈述是:

To begin i'm writing the pipeline entirely as groovy to be checked in to git. Please do not provide any gui necessary solutions. My Problem statement is:

从文件中提取变量并将其设置为 groovy 对象.

Extract a variable from a file and set it equal to a groovy object.

我试过的

def SERVICE_MAJOR_VERSION
node {
    runGitClone(GIT_REPO_URL, GIT_HASH)
    def conf = readFile("gradle.properties")
    echo conf
    //THE BELOW COMMENT DOESN'T WORK
    //SERVICE_MAJOR_VERSION = loadEnvFromFile("SERVICE_VERSION_MAJOR", "gradle.properties", true, SERVICE_VERSION_MAJOR)
}

def runGitClone(git_repo_url, git_hash) {
    checkout changelog: false, poll: false, scm: [$class: 'GitSCM', branches: [[name: git_hash]], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'WipeWorkspace']], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '85572032-4284-4095-9eec-4df70ddfdb68', url: git_repo_url]]]
}

def loadEnvFromFile(string_name, file_path, should_print_load) {
    def par1 = null
    def content = readFile file_path
    def matcher = content =~ /${string_name}=(.+)/
    if (matcher) {
        par1 = string_name + "='" + matcher[0][1] + "'"
        new GroovyShell(this.binding).evaluate(par1)
            if (should_print_load) {
            println par1
        }
    }
    return par1
}

我尝试了其他建议无济于事.特别是以下两个.

I've tried other suggestions to no avail. Particularly the below two.

• 使用 Groovy 从属性文件中获取值
• 将字符串解析为属性

如果您有一个从文件中提取变量并将其设置为 groovy 对象的工作示例，它将解决我的问题.

If you have a working example of extracting a variable from a file and setting it equal to a groovy object it would solve my problem.

推荐答案

已解决:

def content = readFile 'gradle.properties'

Properties properties = new Properties()
InputStream is = new ByteArrayInputStream(content.getBytes());
properties.load(is)

def runtimeString = 'SERVICE_VERSION_MINOR'
echo properties."$runtimeString"
SERVICE_VERSION_MINOR = properties."$runtimeString"
echo SERVICE_VERSION_MINOR
