[jyliu3]

Hi, When I want to use the multipart-handler.jar in my project, I include the following in my gradle.

maven { url 'https://jitpack.io' }

implementation 'com.github.DanielN:multipart-handler:1.0-beta1'

However ,it shows
Could not download multipart-handler.jar (com.github.DanielN:multipart-handler:1.0-beta1),
Anyone has some suggestions?
Thanks a lot.
