Gradlew failed due to download timeout

[Pairman]

Hello! I'm using p4a to build an app using flask. Everything worked until "gradlew failed" when building apk. I guess this is possibly due to download timeout for "gradle-7.4.1-all.zip", and my server indeed has poor connectivity to "service.gradle.org".

Is there any method to download the file manually or switch to a mirror? Thanks in advance.

The log:

Update: I thought the directory name of gradle download would be changed every time randomly. I was wrong. I manually downloaded gradle from a mirror and p4a worked perfrctly again.
