How to publish jar to Nexus(snapshot repository)?

What I want to achieve

I want to publish jar to Nexus snapshot repository.

If you know how to realize, I would like to know.

Detail

I'm planning to publish Java project artifacts (jar) using Gradle from the Jenkins Pipeline to the Nexus3 artifact repository. (But on requirements   I can not use the maven-publish plugin forbuild.gradle. Using maven-publish asgradle publish, I confirms that I can publish to the snapshot repository)

I will publish jar from a Jenkins job.

I would like to publish to snapshot repository , but I was not able to investigate / implement various things.

Survey / Confirmation

According to my research, it seems that there is already the following Jenkins Plugin

However, neither plug-in seems to support Publish to the snapshot repository. (I tried for a while, but I got an error)

Also, calling API in the JenkinsPipeline script using curl was not permitted as follows:

        sh "curl -v -u admin:admin123 \
            -X POST http://localhost:8081/service/rest/v1/components?repository=maven=snapshots \
            -F maven2.groupId=${groupId} \
            -F maven2.artifactId=${artifactId} \
            -F maven2.version=${version} \
            -F maven2.asset1=build/libs/${artifactId}-${version}.jar \
            -F maven2.asset1.extension=jar \
            -F maven2.asset2=build/libs/${artifactId}-${version}.jar \
            -F maven2.asset2.classifier=javadoc \
            -F maven2.asset2.extension=jar \
            -F maven2.asset3=build/libs/${artifactId}-${version}.jar \
            -F maven2.asset3.classifier=sources \
            -F maven2.asset3.extension=jar"
        }

The error message when curling is as follows.

I was having this problem as well. What worked for me was making sure the version number had '-SNAPSHOT' at the end of it, like so: 'com.ex.example-1.0.3-SNAPSHOT' You cannot post a non-snapshot artifact to a snapshot repository in Nexus, and the same goes for a release repository.
