This location is inconvenient for > the Eclipse IDE. > Configure the plugin to write generated sources to {{src/generated/java}} (an > often-used location for generated Java sources) and add this location as a > source folder using {{{}build-helper-maven-plugin{}}}. -- This message was sent by Atlassian Jira (v8.20.1#820001)
