Question

我正在使用Workflow Remote Loader插件的fileLoad函数来加载我的构建脚本的依赖项。在我的主文件中，我有以下内容：

集结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()效果很好，但调用java.getJarVersion时会出现问题。在getJarVersion中，还存在对util的依赖。我的java lib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：

该插件的文档说：

在加载文件的Groovy文件中使用静态初始值设定项从邻居文件加载更多上下文。

我已尝试static def util = fileLoader.load('lib/util.groovy')，但这会产生同样的错误。我也试过各种其他组合无济于事。也许这是对groovy语言缺乏了解？不太确定。

提前致谢！

Answer 1

好的，经过多次试验和错误，我发现了问题。

之前的java.groovy：

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;

原始帖子中省略了return this;行，因为它位于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作为调用java.groovy的范围。当定义为util时，此范围不包括def util = fileLoader.load('lib/util.groovy')。在返回之前将其添加到此文件中，将util放在文件中所有函数调用的范围内。

对于那些来自Google的类似错误消息，您必须安装Pipeline Remote Loader插件。否则会给你：

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

Jenkins Build Pipeline fileLoad库文件无法正常工作
