為什么在此聲明性jenkins管道腳本中找不到mvn命令？

Question

我從https://jenkins.io/doc/book/pipeline/syntax/#tools獲得了這個示例

管道腳本：

pipeline {
    agent any
    tools {
        maven 'apache-maven-3.3.9' 
    }
    stages {
        stage('Example') {
            steps {
                sh 'mvn --version'
            }
        }
    }
}

apache-maven-3.3.9在我的全局工具配置中定義。

腳本的輸出是

為什么找不到mvn命令？

我知道顯然還有其他方法可以執行此操作，但這是Jenkins文檔本身的示例...

這是正確的示例（我也對其進行了測試），但是如果您只有master節點，則它可以正常工作。

我認為您剛剛在Global Tool Configuration中master節點Global Tool Configuration了Maven工具，但是我看到您在SRV-CI-MADE-UNIX節點上執行了您的工作，並且還需要為此節點提供正確的Maven配置。

因此，要解決此問題，我想您需要執行以下步驟：

1. 在為其配置了Maven工具的管道配置（例如master或SRV-CI-MADE-UNIX ）中提供正確的代理（而不是agent any ）；
2. 將Maven安裝在與“ Global Tool Configuration目錄相同的指定節點上，或在“ Manage Jenkins -> Manage Nodes -> <YOUR_NODE> -> Configure -> Node Properties -> Tool Locations為該節點添加特定的Maven工具Manage Jenkins -> Manage Nodes -> <YOUR_NODE> -> Configure -> Node Properties -> Tool Locations
