new File(“path/tmp.txt”) at Jenkins node

I have a very simple pipeline which works on a master. I was reading a line in a tmp.txt which works on Jenkins (master).



stage ('Stage 1'){
node('master') {
File file1 = new File("env.Workspace/tmp.txt")
def String my_line = file1.readLines().get(0)

}
}


I’ve have to move the stage to other one node (slave) and it doesn’t work anymore. If there is a tmp.txt in a workspace of master – pipeline reads it. But I want to read the tmp.txt in a workspace of node, not from master!



stage ('Stage 1'){
node('Agent_1') {
File file1 = new File("env.Workspace/tmp.txt")
def String my_line = file1.readLines().get(0)

}
}


I've found an info that:




“File always implies a file path on the current computer”.




What does it mean? It must be possible to read a file from node..



Can anybody help there?
