I am unable to reproduce this error. Can you try it again?

[futurexiong]

Yes, build failed all the time. Can't make project through 'make project' button directly? Or any other config I should add for plugin 'com.diffplug.gradle.spotles'?

[tiembo]

Can you provide more details? What OS, what version of Studio are you running, does it also fail at the command line?

[futurexiong]

OSX 10.14, Android Studio 3.2. Which command I should execute at the command line?

[tiembo]

./gradlew build.

If you keep running into issues, it may be a problem with your setup rather than with Sunflower code. For that I suggest posting your question at Stack Overflow.

But I can download these two jar with slow connection in the browser.

Seems it's Chinese network connection issue. I use double vpn,then the problem is solved.

[tiembo]

Thanks for adding your solution to this issue.

[samramez]

This is basically a proxy issue. I had a similar issue using my company's wifi and then when I went home and used my home wifi, gradle built successfully.

[VihaanVerma89]

I got this error when my 'Toggle Gradle Mode' was on.

[RamboPan]
