Why Needed: The script simplifies the setup and execution of OpenMetadata by handling Java dependencies, configurations, and environment variables automatically.

We also need to set the folder ‘generated-resources’ in some module’s target folder as “source” folder. IntelliJ IDEA mark target folder as "excluded" by default, we could change it in the module setting. The openmetadata-spec and openmetadata-java-client modules have generated code, need to be changed.
Now run/debug the application.
## Load Sample Data into MySQL
With the OpenMetadata service up and running, run the following commands from the top-level directory
```shell
python3 -m venv venv
source venv/bin/activate
make install_dev generate
cd ingestion
pip install -e '.[sample-data, elasticsearch]'
metadata ingest -c ./pipelines/sample_data.json
metadata usage -c ./pipelines/sample_usage.json
```
- You are now ready to explore the app by going to [http://localhost:8585](http://localhost:8585) *If the web page doesn't work as intended, please take a look at the troubleshooting steps [here](/developers/contribute/build-code-and-run-tests/openmetadata-server#troubleshooting)
## Troubleshooting
- If you see blank page at [http://localhost:8585](http://localhost:8585), please check the logs at logs/openmetadata.log. You might be encountering one of the following errors:
-`connection refused` or `unreachable` - please confirm that MySQL and ES are reachable outside of docker by running `docker ps` and checking that ports 3306 and 9200 are listening on 0.0.0.0
- If ElasticSearch in Docker on Mac is crashing, try changing Preferences -> Resources -> Memory to 4GB
- If ElasticSearch logs show `high disk watermark [90%] exceeded`, try changing Preferences -> Resources -> Disk Image Size to at least 16GB
-`Public Key Retrieval is not allowed` - verify that the JDBC connect URL in `conf/openmetadata.yaml` is configured with the parameter `allowPublicKeyRetrieval=true `
- Browser console shows javascript errors, try doing a [clean build](/developers/contribute/build-code-and-run-tests/openmetadata-server#create-a-distribution-packaging). Some npm packages may not have been built properly.
## Coding Style
1. Configure IntelliJ to disable the [wild-card imports]
