Error with local deployment of a vcenter plugin using vSphere Client SDK 6.7.0

Hi all,

I want to develop my custom vCenter plugin, so I deploy vSphere Client SDK in my development machine, but in the end, I failed to access https://localhost:9443/ui, it shows that "[400] An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - null."

Help highly appreciated

What I do:

1. my development machine is Windows 10, its environment is:

         --java: 1.8.0_60

         --ant: 1.9.15

    2. I have a VCSA6.7(VMware vCenter Server Appliance 6.7.0), and I can access it normally

     3. Download vSphere Client SDK 6.7.0 from https://code.vmware.com/web/sdk/6.7/client

     4. Extract the content of the SDK in a directory, then set the VSPHERE_SDK_HOME and VMWARE_CFG_DIR environment variables:
