Problem starting gradle in an Android project for the first time

Help/Discuss
1

The first thing my ide tells me when I start the project is:
-------------------- NOTE --------------------
Gradle Wrapper is not available!
Install a default one. Gradle v7.4 will download if needed.

Then I start to download something and I get an error.

Starting build...
 Creating Idea project model...

FAILURE: Build failed with an exception.

I really don’t understand why that happens to me, I guess it’s because of my connection, that the synchronization fails, in any case there would not be a way for me to download whatever I’m downloading manually or something like that, sorry if I misunderstand the situation is that I don’t know much about gradle.

“Gradle Wrapper is not available” most probably means that the project you are trying to import does not have the four Gradle Wrapper files that practically any Gradle build should contain in their source code, as it defines exactly which version of Gradle to use to execute the build and thus prevents failing builds because of version conflicts / breaking changes done in Gradle: The Gradle Wrapper.

Regarding the “Could not find …”, these are strange.
I just tried to download the file from the given URL and it works perfectly fine.
So I’d say just retry it, maybe with --refresh-dependencies from the command-line in case Gradle remembers it didn’t find them.
If it still does not work, I’d suspect some firewall, proxy, or anti-virus that is intervening on your side.

Hello i have the same issue, i tried to download the file manually and it worked perfectly but when im trying to build my flutter apps it tolds this:

As you can download it with your browser, same assumption as in my last post. You probably need to use some proxy that you have configured in your browser, but not for Gradle.

Or you use a broken Java to run Gradle where the HTTPS certificates are not good.
But you should see that more verbose up in the log, maybe with --info or latest --debug.
Something like “could not build PKIX path”.
If that is the case, try to run Gradle with a different / freshly installed Java.
