Hi Dominik,
Thank you very much for your enquiry. The use of the JPADatabase is
documented here (only maven syntax, but gradle should be equivalent):
http://www.jooq.org/doc/latest/manual/code-generation/codegen-jpa
<generator>
<database>
<name>org.jooq.util.jpa.JPADatabase</name>
<properties>
<!-- A comma separated list of Java packages, that contain
your entities -->
<property>
<key>packages</key>
<value>com.example.entities</value>
</property>
</properties>
</database></generator>
If a "database" requires additional arguments like in this case the
packages containing entities, this is done through a generic properties
"hashmap". In your case, you would probably need to write:
jooq {
sample(sourceSets.main) {
generator {
name = 'org.jooq.util.DefaultGenerator'
strategy {
name = 'org.jooq.util.DefaultGeneratorStrategy'
}
database {
name = 'org.jooq.util.jpa.JPADatabase'
properties {
property {
key = 'packages'
value = 'com.example.jpa'
}
}
}
generate {
}
target {
packageName = 'com.example.db'
directory = 'src/main/java'
}
}
}
}
Please, let me know if this helps.
Best Regards,
Lukas
