Jenkins: Get GIT output into an array-CodePudding

I am currently using the bellow code to get a list of files that were changed between current commit and master branch:

        gitOutput = bat script: "git diff-tree -r --no-commit-id --name-only HEAD origin/master", returnStdout: true
        changedFiles = gitOutput .split("\n")
        echo changedFiles.toString()

This is the output I am getting:

[
, D:\home\jenkins\myjob>git diff-tree -r --no-commit-id --name-only HEAD origin/master 
, Jenkinsfile, MyData/Program.cs]

The output I'd like to get would be:

[Jenkinsfile, MyData/Program.cs]

I've tried to add .trim() but I'm getting:

No signature of method: [Ljava.lang.String;.trim() is applicable for argument types: () values: []

And I'm not sure how to remove the elements that are my command and not the actual output

CodePudding user response：

This happens because you directly assign the bat command to the variable, which results in your command and its' output being written into the variable.

To avoid this, use:

def gitOutput = bat(script: script, returnStdout: true)

where the script is the command that needs to be run. This will return only the output and not the command as well.

I found a solution by using: listOfFiles[2..-1] I can drop the first 2 elements and have what I need
