Artifacts

distribution/proxy/target/apache-shardingsphere-<version>-shardingsphere-proxy-bin.tar.gz

<version> is the project version of the source being built.

The Proxy archive’s lib directory contains runtime dependencies, selected Hive and Seata AT modules are placed in opt-lib, and ext-lib is for user-supplied dependencies.
