some time see people use "manager" object, how can access ? alos ideas on how accomplish task ?

problem groovy system script run in jenkins master node, while workspace file path in jenkins slave node, doesn't exist in master node.

you can verify code

thedir = new file(envvars.get('workspace')) println thedir.exists()

it return false

if don't use slave node, return true

solution can't use normal file, have use filepath http://javadoc.jenkins-ci.org/hudson/filepath.html

if(build.workspace.isremote()) {     channel = build.workspace.channel;     fp = new filepath(channel, build.workspace.tostring() + "/node_details.txt") } else {     fp = new filepath(new file(build.workspace.tostring() + "/node_details.txt")) }  if(fp != null) {     fp.write("test data", null); //writing file }

then works in both case.
