Allow Insecure Protocols, Android Gradle

I recently updated my android studio to Arctic Fox and got an error in my project
A problem occurred configuring root project 'so10'.
> Could not resolve all dependencies for configuration ':classpath'.
> Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository
'maven3()' to redirect to a secure protocol (like HTTPS) or allow insecure protocols.
See for more details.
This is my gradle where the problem occurs
repositories {
// maven { url ' }
maven { url "" }
maven { url ' }
maven { url '
maven { url "" }
maven { url ' }
google()
mavenCentral()
jcenter()
}
How do I solve it?

For insecure HTTP connections in Gradle 7+ versions, we need to specify a boolean allowInsecureProtocol as true to MavenArtifactRepository closure.
Since you have received this error for sonatype repository, you need to set the repositories as below:
- Groovy DSL
repositories {
maven {
url ""
allowInsecureProtocol = true
}
// other repositories ...
}
- Kotlin DSL
repositories {
maven {
url = uri("")
isAllowInsecureProtocol = true
}
// other repositories ...
}
or you can just replace HTTP with HTTPS.
For those using the Kotlin DSL, the property name is different isAllowInsecureProtocol
maven {
url = uri("")
isAllowInsecureProtocol = true
}
Note that Gradle 7 onwards, any insecure URL is blocked, not only for repositories, so applying scripts would also fail.
apply from: ""
Applying script plugins from insecure URIs, without explicit opt-in, is unsupported.
If you can't use HTTPS for whatever reasons, then do the following:
apply from: resources.text.fromInsecureUri("")
However, if I were a Gradle dev, I'd provide a org.gradle.allow-insecure-protocol=true to be set in the gradle.properties and be done. I've opened for that.
Add allowInsecureProtocol = true for all unsecure http in repositories e.g.
maven {
url ""
allowInsecureProtocol = true
}
maven {
url ""
allowInsecureProtocol = true
}
For me, coding the assignment statement "allowInsecureProtocol = true" stopped working** in a recent workspace using Gradle 7.x (the reason as yet, is unknown.) I found that when I instead coded setAllowInsecureProtocol(true) and it was OK again.
maven { url "";
setAllowInsecureProtocol(true);
// allowInsecureProtocol = true
}
I have no info about exactly when the assignment statement stopped working.
Also, regarding comments about using https instead - I get it - it's good advice, but in this instance that is out of my control.
** referring to the build.gradle ...maven clauses
I solved this problem,by change my gradle version.Because my project need gradle version is lower than the Android Studio given.
I tried to switch to maven2 solved my problem
maven2 {
url ""
allowInsecureProtocol = true
}
