Project not building due to missing dependency

[josemmo]

jCenter has been deprecated since February 2021, giving a 403 Forbidden response to any request to "dl.bintray.com". In consequence, dependency "com.goterl.lazycode:lazysodium-android" cannot be fetched.

Related to https://github.com/CrowdNotifier/crowdnotifier-sdk-android/issues/26.

Steps to reproduce

1. Clone repository
2. Checkout "develop" branch
3. Run ./gradlew build

Gradle error log

Proposed solutions

Either upgrade "org.crowdnotifier:crowdnotifier-sdk-android" to v4.0.0 (still in development and with breaking changes) or provide the AAR dependency file for "com.goterl.lazycode:lazysodium-android" mannually:

 allprojects {
     repositories {
         google()
         jcenter()
-         maven {
-            url  "https://dl.bintray.com/terl/lazysodium-maven"
-        }
+        flatDir {
+            dirs 'ext-libs'
+        }
     }
 }
