JOOQ 生成器：缺少名称

Question

I'm trying to setup JOOQ with Postgres and Gradle.

Whenever I run the generate task I get ~ 20 Ambiguous type names :

Ambiguous type name: The object pg_catalog.generate_series generates a type one.dbtest.db.pg_catalog.tables.GenerateSeries which conflicts with the existing type one.dbtest.db.pg_catalog.tables.GenerateSeries on some operating systems. Use a custom generator strategy to disambiguate the types.

and hundreds of these:

Missing name: Object jsonb_exists_all holds a column without a name at position 2 Missing name: Object jsonb_exists_any holds a column without a name at position 1 Missing name: Object jsonb_exists_any holds a column without a name at position 2 Missing name: Object jsonb_ge holds a column without a name at position 1 Missing name: Object jsonb_ge holds a column without a name at position 2 Missing name
: Object jsonb_gt holds a column without a name at position 1 Missing name: Object jsonb_gt holds a column without a name at position 2 Missing name: Object jsonb_hash holds a column without a name at position 1 Missing name: Object jsonb_in holds a column without a name at position 1 Missing name
: Object jsonb_le holds a column without a name at position 1 Missing name: Object jsonb_le holds a column without a name at position 2 Missing name: Object jsonb_lt holds a column without a name at position 1 Missing name: Object jsonb_lt holds a column without a name at position 2 Missing name
: Object jsonb_ne holds a column without a name at position 1 Missing name: Object jsonb_ne holds a column without a name at position 2

Do I need to exclude the pg* types?

The generate task is taken from the JOOQ samples:

task generate << {
  def writer = new StringWriter()
  def xml = new groovy.xml.MarkupBuilder(writer)
    .configuration("xmlns": "http://www.jooq.org/xsd/jooq-codegen-3.7.0.xsd") {
    jdbc() {
      driver("org.postgresql.Driver")
      url("jdbc:postgresql://localhost/pagila")
      user("xxx")
      password("xxx")
    }
    generator() {
      database() {
        name { mkp.yield( 'org.jooq.util.postgres.PostgresDatabase' ) }
        exclude("pg.*")
      }
      generate() {}
      target() {
        packageName("one.dbtest.db")
        directory("src")
      }
    }
  }

  //println writer.toString()

  org.jooq.util.GenerationTool.main(
    javax.xml.bind.JAXB.unmarshal(
        new StringReader(writer.toString()),
        org.jooq.util.jaxb.Configuration.class
    )
  )
}

Answer 1

For Postgres you also have to specify the input schema, so it's:

generator() {
  database() {
    name { mkp.yield( 'org.jooq.util.postgres.PostgresDatabase' ) }
    inputSchema("public")
  }
[..]

Answer 2

Add <inputSchema>public</inputSchema> in <database> block in your pom.xml file if you have added <name>org.jooq.meta.postgres.PostgresDatabase</name> in generator.
