deploying-java-sdk-bundles
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.
Install
With your agent
Install OMGSkills skill "astronomer/agents:skills/deploying-java-sdk-bundles" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/astronomer/agents /tmp/agents && ln -s /tmp/agents/skills/deploying-java-sdk-bundles ~/.claude/skills/deploying-java-sdk-bundlesFrom 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.
