Gretty supports debugging a farm with a set of special gradle tasks: farmRunDebug, farmRunWarDebug, farmStartDebug, farmStartWarDebug.
When you invoke one of the debugging tasks, a farm starts servlet-container with all farm web-apps, in suspended mode, and waits for debugger commands on port 5005.
|Author of Gretty plugin tested farm debugging under Netbeans IDE. In principle, it should work under other Java IDEs as well, but it’s not tested yet.|
|The project, containing a farm, must be a JVM project (Java, Groovy, etc.), otherwise IDE does not send debugging commands to the debugged JVM process over port 5005. This requirement is easily fulfilled, when you define a farm in one of the web-apps.|
