Today’s development feedback has been using the good Jenkins compilation service, but it reported an error

Look at the log and say something is wrong with deletedir

org.jenkinsci.plugins.workflow.steps.MissingContextVariableException: Required context class hudson.FilePath is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node

Then after development and adjustment

Start reporting another error

After developing no solution, he found me

I looked at the pipeline

pipeline {
    agent{ label 'qa-gpu016.test.cn' }
    parameters {
        string(defaultValue: '0.0.0', description: '版本号', name: 'version', trim: false)
    }
......

The discovery task is scheduled to · qa-gpu016 test.cn , and then log in to qa-gpu016 test.cn View

It was found that the disk was full. Because I didn’t know who to clean, I could only clean some unused images and containers

Then inform the developer to remove the judgment and keep it as it is

Reconstruction, development feedback, pulling an image, and now entering the compilation process. Before, an error was reported on the outside

So far, the problem has been solved
