Notes for Developers

For Java 11 install, if If you change the xsd (REST API message definitions), then you will need to regenerate gensrc via JAXB in Java 8. In the i2b2-core cell directory for which you're regenerating the XSD-Java, run the ant target "jaxb_gen" on Java 8 and then build as usual using Java 1117.

Note about the beta release

In this beta release, clicking Create File on a custom-table data request in a Postgres database does not actually generate the file.
