Build failed cause mxnet.dll is not a valid Win32 application

"Unable to load library 'C:\Users\Default.mxnet\cache\1.6.0-b-SNAPSHOT-20200120mkl-win-x86_64\mxnet.dll'
This message looks suspicious. Somehow java think you are running as user "Default", that's strange.

Would you please run following command and collect the output:

cd integration
..\gradlew debugEnv

If you are login as administrator in Windows, the correct location of mxnet.dll should look like following:

C:\Users\Administrator\.mxnet\cache\1.6.0-b-SNAPSHOT-20200120mkl-win-x86_64\mxnet.dll

Somehow your path missing a \ after Default

Ouch, I have to explain, do not pay attention to it. I just replaced manually real user name.
It should looks like "" 'C:\Users\UserName.mxnet\cache\1.6.0-b-SNAPSHOT-20200120mkl-win-x86_64\mxnet.dll'
Also, see logs in attach:
build.log
debugEnv.log

I guess this is caused by you running gradle in MingW64 shell. Please try to run gradle in command prompt.

@frankfliu
Unfortunately, the same result in command prompt. =(

This is really strange, mxnet.dll is a 64-bit DLL, and your java and windows are both 64-bit. Somehow your system trying to load mxnet.dll in 32-bit mode and failed.

Can you try one more thing: delete C:\Users\UserName.mxnet folder and try it again?
Another thing to try is: install vs2015 redistribution package, see: https://github.com/awslabs/djl/blob/master/docs/development/troubleshooting.md#3-build-fails-on-windows-caused-by-unsatisfiedlinkerror

Many thanks, reinstalling vs2015 solved the problem.
I should have read Troubleshooting more accurate.
