Adrien Guichard commented on GROOVY-11359: ------------------------------------------ Here is how I process. If your process is any better, I would be happy to know about it: 1/ Attach *jdb* to {*}groovyc{*}: {{*jdb* -sourcepath /home/xXx/dev/groovy/groovy-3.0.21/src/ -attach 5005}} 2/ Trace all what's happening: {{*dbgtrace*}} 3/ Launch with: *{{cont}}* Here I obtain lot of traces, but I can guess the Expressions, they appears in traces:{{{}{}}} {{[JDI: Looking up Class, signature='Lorg/codehaus/groovy/ast/expr/{*}CastExpression{*};', id=2764]}} I think I can improve this process with dbgtrace {*}flags{*}, but I do not find any docs, and jdb {*}scripting{*}. If you have a better process, just let me know ! It is a long time since I used dbx, adb and others. I really liked those tools, and I do not really enjoy debugging via an IDE (I like IDE, but not to focus on debugging..).
