Builds and deploys compiled Airflow Java SDK bundles so workers can run them. Use when the user wants to package a JVM task bundle into a JAR, asks about the \`org.apache.airflow.sdk\` Gradle plugin, \`./gradlew bundle\`, the Maven shade/BOM setup, fat vs thin JARs, the logging integration artifacts (JPL, SLF4J, Log4j 2, JUL), preview/snapshot builds, or getting the JAR onto an Airflow worker (Docker, Kubernetes, or Astro). For the task code see authoring-java-sdk-tasks; for the Airflow coordinator settings see configuring-airflow-language-sdks.

## From README

Deploying Java SDK Bundles A Java SDK deployment has one artifact: a bundle — your compiled task classes plus the SDK, packaged as a JAR (or a thin JAR alongside its dependency JARs). You build it with Gradle or Maven, then place it in a directory that the JavaCoordinator scans (jarsroot) on every worker. This skill is platform-neutral; it shows the build once, then both an open-source and an Astro deployment path. Experimental. The Java SDK is in preview. Artifact versions below are shown as ${version}; while the SDK is pre-release you may need to build the artifacts into your local Maven repository yourself (see the preview builds section). Order of operations: build the bundle (this skill) → place it where jarsroot points → configure the coordinator (configuring-airflow-language-sdks). The task code itself is authoring-java-sdk-tasks.
