how to debug a grails application without an ide?

[Mauro-4]

I'm not using an ide.
How can I debug my application, inserting brak points, etc.?

I don't think you can. Along time ago I once used a text/command line based debugger for debugging some C code. Don't know if such a thing exists for Java or not.

But why wouldn't you use an IDE? Most of them are free.

Netbeans or STS for example?

Maybe because IDEs suck! Or maybe because I prefer text editors.

Netbeans or STS for example?

There are some examples on the web on using netbeans and STS for debugging grails app, if you must do so. If I ever have the need to debug a grails app I would only use the IDE for debugging and go back to my text editor for editing.

Yes I don't like ides too but it seems that is the only way for
debugging a grails app.

There is always jdb (the gdb-alike command line Java debugger that comes
with the JDK) but I don't know how well that plays with Groovy code.
You're probably better off with a few well-placed println or log.debug
statements.  I am an IDE user about 60-70% of the time and I still do
most of my debugging using logging - I rarely, if ever, use "breakpoint
and step through" style debugging.

You could use jdb:

You can even script your debugging using Groovy with YouDebug: http://youdebug.kenai.com/.
Basically, it is a Groovy wrapper around the Java Debug Interface (JDI) created by Kohsuke Kawaguchi, the inventor of Hudson/Jenkins. This is great e.g. if you have to wait for certain conditions, which can be scripted in Groovy.

HTH,

I install STS eventually.
