title: Why does jOOQ suggest to put generated code under "/target" and not under "/src"?
body: <p>Looking at the <a href="http://www.jooq.org/doc/3.4/manual/code-generation/codegen-configuration/#N27748" rel="noreferrer">jOOQ example</a> of the Maven plugin configuration for the code generator (near the end of the configuration), I see that the target directory for the generated files is <code>target/generated-sources/jooq</code>.</p>
  
  <p>Since the generator produces Java code, do you know why the suggestion here isn't a subfolder of <code>/src</code>, but instead a completely separated one? Is there any reason for this? Is it a best practice or something?</p>
