The Dag processor still receives ``sales_pipeline.py`` through the separate Dag delivery process. +A Dag processor with this ``[sdk]`` configuration also parses the executable JARs of every Dag bundle, +and needs a JRE to do so (see :ref:`java-sdk/native-dag-parsing`). +The ``java-task-handlers`` bundle only holds the JARs that the Python Dag's tasks run, +so keep the Dag processor from parsing it by listing ``*`` in its ``.airflowignore``: + +.. code-block:: bash + + echo '*' > /opt/airflow/jars/sales-pipeline/.airflowignore Review Comment: This only works when the handler JARs have their own bundle. If task_handler_bundle_name is unset, the JAR sits next to the Python Dags and * would hide those too, so that case needs *.jar. Also * isn't a valid regex, so with dag_ignore_file_syntax = regexp the rule gets dropped and the JARs are still parsed. Can the docs show both cases and both syntaxes? -- This is an automated message from the Apache Git Service.
