• No.

Describe the feature you would like.

• Why is the org.apache.shardingsphere:shardingsphere-agent:5.5.0 JAR not published to Maven Central? I looked at https://repo1.maven.org/maven2/org/apache/shardingsphere/shardingsphere-agent/5.5.0/ and found that there was only the definition file for the POM.

sdk install java 22.0.2-graalce
sdk install maven 3.9.9
mvn clean dependency:get -Dartifact=org.apache.shardingsphere:shardingsphere-agent:5.5.0

• I have the impression that this is not a normal limitation of the ASF. It is actually quite cumbersome to manually compile org.apache.shardingsphere:shardingsphere-agent:5.5.0 as documented at https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-jdbc/observability/ .
• In case I missed any issues, we actually also have JARs that publish binaries at https://apache.jfrog.io/ui/packages .
• Likewise, there is no restriction on publishing a Docker Image containing the shardingsphere agent to Docker Hub, like https://hub.docker.com/r/apache/skywalking-java-agent . Ideally, we should be able to download files directly from a Docker Image and insert similar statements into the downstream Dockerfile.

COPY --from=apache/shardingsphere-agent:5.5.0 /apache-shardingsphere-5.5.0-shardingsphere-agent-bin ./apache-shardingsphere-agent/

@linghengqian Hi,
I think this is unnecessary, because shardingsphere-agent and shardingsphere-proxyare strongly related. And the shardingsphere-proxy artifact already contains the shardingsphere-agent.

Can download it from the official website address https://shardingsphere.apache.org/document/current/en/downloads/

• The problem is that https://shardingsphere.apache.org/document/current/en/downloads/ only provides the latest version. I think we should provide nightly builds of ShardingSphere Agent at https://github.com/orgs/apache/packages?repo_name=shardingsphere to provide for ShardingSphere JDBC testing, just like ShardingSphere Proxy. This can avoid checking in a lot of JAR binaries to git in recurring issues like Using the OpenTelemerty plugin with Agent will throw some undocumented exceptions #32793 and https://github.com/linghengqian/shardingsphere-agent-master-test .
• A possible Dockerfile might look like,

FROM alpine AS prepare
# `APP_NAME` will be dynamically set to `apache-shardingsphere-5.5.1-SNAPSHOT-shardingsphere-agent-bin` from `distribution/agent/pom.xml`
ARG APP_NAME
ADD target/${APP_NAME}.tar.gz /opt
RUN mv /opt/${APP_NAME} /opt/shardingsphere-agent

FROM eclipse-temurin:22-jdk
MAINTAINER ShardingSphere "dev@shardingsphere.apache.org"
ENV LOCAL_PATH /opt/shardingsphere-agent
COPY --from=prepare /opt/shardingsphere-agent /opt/shardingsphere-agent

Can you try to implement it?

• I will submit a PR in the near future to show a prototype Docker Image.
