  • Java

      • Continuation indent should be 8.
    • Javadoc: 
      • Do not wrap on line javadoc comment needs to be enabled
      • Preserve line feeds

      • Order must be manually defined, see specification above
  • Xml
    • Tabs and Indents: Set continuation indent to 2
    • Other: Disable Align attributes.

Headers

We add the following header to all our Java-files. This is done by using the maven-license-plugin. All headers can be updated by running the license:update-file-header: 

...

public JobSupervisor(Provider<JobDAO> jobDaoProvider, Provider<Long> jobTimeoutProvider) {

The Provider<X> interface provides a get() method returning X.  This allows for lazy initialization and/or providing an unknown number of X'es.
