I have successfully published the jar to Maven Central https://repo1.maven.org/maven2/, and I can also use it in my project, but why I can't find it in MVNrepository https://mvnrepository.com.
Here is the jar:
<dependency>
<groupId>io.github.phantom0103</groupId>
<artifactId>elem-open-sdk</artifactId>
<version>2.0.0</version>
</dependency>
