Failed to use 1.1.0-RC with maven and just release repositories

Describe the bug

To Reproduce We put the following dependency on our project:

        <dependency>
            <groupId>org.jetbrains.kotlinx</groupId>
            <artifactId>kotlinx-serialization-json</artifactId>
            <version>1.1.0-RC</version>
        </dependency>

The following error is popping up:

[ERROR] Failed to execute goal on project web-api: Could not resolve dependencies for project co.c.prod.jp:web-api:jar:kotlinSerialization-000101: Failed to collect dependencies at org.jetbrains.kotlinx:kotlinx-serialization-json:jar:1.1.0-RC -> org.jetbrains.kotlinx:kotlinx-serialization-json-jvm:jar:1.1.0-RC -> org.jetbrains.kotlin:kotlin-stdlib:jar:1.4.30-270: Failed to read artifact descriptor for org.jetbrains.kotlin:kotlin-stdlib:jar:1.4.30-270: Could not transfer artifact org.jetbrains.kotlin:kotlin-stdlib:pom:1.4.30-270 from/to central-maven (http://repo1.maven.org/maven2): Transfer failed for http://repo1.maven.org/maven2/org/jetbrains/kotlin/kotlin-stdlib/1.4.30-270/kotlin-stdlib-1.4.30-270.pom 501 HTTPS Required -> [Help 1]

It seems that 1.1.0-RC is declaring a dependency on the stdlib version 1.4.30-270, which is not available on repo1.

Expected behavior Maven project should build with no issues.

Environment

• Kotlin version: 1.4.30
• Library version: 1.1.0-RC
• Kotlin platforms: JVM
• Maven version: 3.6.3

I excluded kotlin-stdlib and kotlin-stdlib-common, that force to use kotlin 1.4.30

        <dependency>
            <groupId>org.jetbrains.kotlin</groupId>
            <artifactId>kotlin-stdlib</artifactId>
            <version>1.4.30</version>
        </dependency>
        <dependency>
            <groupId>org.jetbrains.kotlinx</groupId>
            <artifactId>kotlinx-serialization-json</artifactId>
            <version>1.1.0-RC</version>
            <exclusions>
                <exclusion>
                    <groupId>org.jetbrains.kotlin</groupId>
                    <artifactId>kotlin-stdlib</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.jetbrains.kotlin</groupId>
                    <artifactId>kotlin-stdlib-common</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

I think it can be closed now that version 1.1.0 is out

Indeed it seems so, I removed the exclusions and there do not appear to be any errors in the Maven project. The dependencies now point to Kotlin 1.4.30 final versions.

However, I think it’s something for JetBrains to pay attention to for the next RC release that is published to Maven Central.
