i am getting the following error on android when trying to build:

Could not resolve all artifacts for configuration ':wowmaking_react-native-iron-source:releaseRuntimeClasspath'.
   > Could not resolve com.facebook.react:react-native:+.
     Required by:

it started happening from yesterday

I had this as well and it went away once the Gradle / JCenter outage had passed.
The issue is not the use of bintray by this project (for which there's an open PR: #85), but the use of JCenter by the IronSource Android SDK.

@hdemmer I have this exact error message since Friday as well. But I don't quite understand. Do you mean that wowmaking/react-native-iron-soruce is alright, but the IronSource Android SDK is using JCenter? I read that JCenter is shut down since 2021. I am so totally confused how could IronSource Android being built at all for this whole year, well, until Friday? Do you mean that JCenter just shut down, and could be back on sometime (soon I hope)? What should I do to fix it? Many thanks!

Hi @rachellauyui
Hope you were able to fix things in the meantime. I assume that some cached version was on your disk and finally got lost. JCenter will not come back afaik.
You have to add the changes from the open PR since this project is unmaintained. To use it reliably, fork the project, add the change, then point your package.json to the fork.

I solved my problem by using the below line in android/build.gradle.

allprojects {
    repositories {
...
        maven { url 'https://android-sdk.is.com/' }
...
    }
}
