Jenkin automatic tools instllation is called multiple times

HI ,

I am creating a plugin to have automatic tools for my custom MATLAB where i am using DownloadFromURLInstaller class and overriding performInstallation method

However in the log i am seeing whatever do in performInstallation method its performed twice before it exits the method. i could not get why is this happening. Any help would be appreciated.
