Running windows slave and  generating android output file *.apk and needs to be copied on master machine so installed plugin and logs are printed as below :

[copy-to-slave] Copying 'C:\JenkinsSlave\workspace\abc\PLATFORM\android\CordovaBaseProject\platforms\android\build\outputs\apk\abc.apk', excluding nothing, from 'file:/C:/JenkinsSlave/workspace/abc/PLATFORM/android/' on 'hudson.slaves.DumbSlave[Android slave]' to 'file:/mnt/jenkins/builds/workspace/abc/' on the master.
Finished: SUCCESS

First try to copy files from same machine from slave to master.

Now,another try is slave is running on mac machine and master is running on windows VM which is linux based now, try to copy file from mac machine to master, same logs messages are printed but no file copied.

Where to see copied file path, it seems it's not correct path, Please fix the issue as soon as possible.
