The name 'GetDrive' does not exist in the current context

Hi,I am using Jenkins to build my unity project for Android platform on Ubuntu18.04.
When Unity try to compile your plugin's code on the SimpleDiskUtils/Plugins/DiskUtils/DiskUtils.cs,
Unity will throw Scripts have compiler errors error.

Log shows that:

Assets/ThirdParty/SimpleDiskUtils/Plugins/DiskUtils/DiskUtils.cs(144,25): error CS0103: The name 'GetDrive' does not exist in the current context
Assets/ThirdParty/SimpleDiskUtils/Plugins/DiskUtils/DiskUtils.cs(155,25): error CS0103: The name 'GetDrive' does not exist in the current context
Assets/ThirdParty/SimpleDiskUtils/Plugins/DiskUtils/DiskUtils.cs(166,25): error CS0103: The name 'GetDrive' does not exist in the current context

In DiskUtils.cs, line 87, I try to fix this bug with this:
before:

#elif UNITY_STANDALONE_WIN || UNITY_EDITOR_WIN

after

#elif UNITY_STANDALONE_WIN || UNITY_EDITOR_WIN || UNITY_EDITOR_LINUX

With this modification, Unity will not show complier error in DiskUtils.cs, but I don't now whether my modification will bring other bugs for other platform.

replace
DriveInfo drive = GetDrive (DEFAULT_DRIVE);
with
DriveInfo drive = new DriveInfo(DEFAULT_DRIVE);
