Get the name of the latest changed files

I need to get the name of the files of the last changes, only the names:
eg
```
-file1.java
-file2.java
```
What I already have tried:
```
stage("last-changes") {
steps {
script {
def publisher = LastChanges.getLastChangesPublisher "PREVIOUS_REVISION", "SIDE", "LINE", true, true, "", "", "", "", ""
publisher.publishLastChanges()
def changes = publisher.getLastChanges()

println('changes:')
println(changes)

println('getEscapedDiff:')
println(changes.getEscapedDiff())

println('getDiff:')
println(changes.getDiff())

for (commit in changes.getCommits()) {
last_changes = commit.getChanges()
println('COMMIT:')
println(commit)
def commitInfo = commit.getCommitInfo()
println('commitInfo:')
println(commitInfo)

println('commitMessage:')

println(commitInfo.getCommitMessage())

println('LastChanges:')
println(last_changes)
}
}
}

}
```
But I didn't find an way to get the name of the files, just the `changes.git Diff()` is resulting something related with what I want, but it shows the `git diff` method too.

There is any way to accomplish this, only the name of the last changed files?
