Jenkins Build Pipeline fileLoad 在库文件中不起作用

Question

我正在使用 Workflow Remote Loader 插件的 fileLoad 函数为我的构建脚本加载依赖项。在我的主文件中，我有以下内容：

构建-app.groovy

def java
def util

node {
    stage "Setup"
    fileLoader.withGit('git@github.com:myorg/build-scripts.git', 'master', '234720asdf8ed1a2', '') {

        java = fileLoader.load('lib/java.groovy');
        util = fileLoader.load('lib/util.groovy');
    }

    util.checkIfFileExists('myFile.txt')
    def version = java.getJarVersion("api")
}

util.checkIfFileExists() 完美运行，但在调用 java.getJarVersion 时出现问题。在 getJarVersion 中也存在对 util 的依赖。我的java库如下：

java.groovy

def util = fileLoader.load('lib/util.groovy')

def getJarVersion() {
    ...
    util.checkIfFileExists('myFile.txt')
    ...
}

当我在 Jenkins 中运行时出现以下错误：

插件的文档说：

Use static initializers within the Groovy file of the loaded file to load more context from neighbor files.

我已经尝试过 static def util = fileLoader.load('lib/util.groovy')，但这产生了同样的错误。我也尝试过各种其他组合无济于事。也许这是对 groovy 语言的理解不足？不太确定。

提前致谢！

Answer 1

好的，经过反复试验，我找到了问题所在。

java.groovy之前：

def util = fileLoader.load('lib/util.groovy')

def getJarVersion() {
    ...
    util.checkIfFileExists('myFile.txt')
    ...
}

return this;

java.groovy 之后：

def getJarVersion() {
    ...
    util.checkIfFileExists('myFile.txt')
    ...
}

this.util = fileLoader.load('lib/util.groovy')
return this;

原来的 post 中省略了 return this; 行，因为它在远程文件加载器插件的文档中，但它是关键。当从 build.groovy 加载 java.groovy 时，它使用返回的 this 作为对 java.groovy 调用的范围。此范围在定义为 def util = fileLoader.load('lib/util.groovy') 时不包括 util。在返回之前将其添加到此文件中，将 util 置于文件中所有函数调用的范围内。

对于那些从 Google 收到类似错误消息的人，您必须安装 Pipeline Remote Loader 插件。否则它会给你：

groovy.lang.MissingPropertyException: No such property: fileLoader for class: groovy.lang.Binding
