Please deploy simple petitparser-core

I don't need all the additional JARs and would be happier if i could only pull in core.

I tried with:

<dependency>
    <groupId>com.github.petitparser</groupId>
    <artifactId>petitparser-core</artifactId>
    <version>2.0.0</version>
</dependency>

but this is not deployed.

This should work, but I couldn't try yet:

    <dependency>
        <groupId>com.github.petitparser.java-petitparser</groupId>
        <artifactId>petitparser-core</artifactId>
        <version>2.0.0</version>
    </dependency>

See here for an example: https://github.com/jitpack/maven-modular
