lombok @SuperBuilder is not compatible

[lvjj]

The List of the Ebean 15.10.0 @onetomany field needs to be initialized, but the Lombok @SuperBuilder initialization field is not recognized by Ebean,

[rbygrave]

You will have to be more explicit.

What is an example of using @SuprtBuilder on an entity bean?
What is the bytecode that is produced by Lombok for that?
What does "the lombok @SuperBuilder initialization field is not recognized by Ebean" mean?

@rbygrave Thanks for devoting time to this issue.

[rbygrave]

This is effectively a bug in ebean-agent. Refer ebean-orm/ebean-agent#224

[rbygrave]

This is fixed in the ebean-agent / ebean-maven-plugin / ebean-gradle-plugin version 14.12.0 and 15.12.0

An updated ebean IntelliJ IDEA plugin has been published, that usually takes 2 days to be approved and then publicly available. To use the updated ebean-agent before then.

• Download the ebean-agent 15.12.0 jar from https://repo1.maven.org/maven2/io/ebean/ebean-agent/15.12.0/ebean-agent-15.12.0.jar
• mkdir ~/.ebean
• Move the ebean-agent jar into ~/.ebean
• Toggle OFF the ebean plugin
• Toggle ON the ebean plugin (this will then look for an ebean agent in ~/.ebean and use one if it is found)

Running the application in IntelliJ will then use the ebean agent from ~/.ebean

PR to bump the ebean-agent - #3620

[rbygrave]

Let us know if you can confirm that the lastest ebean-agent fixes the issue. Thanks Rob.

i replace ebean-agent-15.20.0.jar => idea/plugins/ebean-idea/lib/ebean-agent-15.10.0.jar, it's worked, Thinks rgygrave
