I debug netbeans by adding to etc/netbeans.conf netbeans_default_options string -J-agentlib:jdwp=transport=dt_socket,suspend=n,server=y,address= 127.0.0.1:61826
then run that netbeans and use a 2nd instance of netbeans to attach to the address above and set breakpoints/etc. The relevant source code of netbeans is opened as a project so the debugging netbeans can show source for breakpoints. one netbeans is used as the target for debugging and the 2nd for the debugging. -Gary On Sat, Jun 16, 2018 at 4:24 AM, Jan Lahoda <[email protected]> wrote: > Hi, > > On Fri, Jun 15, 2018 at 8:58 PM, Peter Steele <[email protected]> > wrote: > > > Is there a guide any where for building netbeans in the netbeans ide so > you > > can use netbeans to debug things? > > > > To work on NetBeans itself (on a module or a set of modules from the main > repository), I think this approach is used typically: > -ensure the IDE is built (either using command line or from IDE as show in > the Geertjan's page) (this typically does only need to be done when > significant changes are made to the sources, often by pulling in external > changes). > -open the set of modules you want to work on > -then "Run", "Debug" and "Test" should work, when opening a single test > file, it should be possible to run and debug the test, etc. These should be > fairly fast, as these don't need to rebuild everything. > > Jan > > > > > > On Fri, 15 Jun 2018, 19:48 Dmitry Avtonomov, < > [email protected]> > > wrote: > > > > > Thanks Matthias and Gj! > > > > > > I've added the extra Debug line to confluence wiki: > > > > > > https://cwiki.apache.org/confluence/display/NETBEANS/ > > Development+Environment > > > > > > On Fri, Jun 15, 2018 at 11:33 AM Matthias Bläsing < > > > [email protected]> > > > wrote: > > > > > > > Hi Dmitry, > > > > > > > > Am Freitag, den 15.06.2018, 11:02 -0700 schrieb Dmitry Avtonomov: > > > > > Just wanted to point out that: > > > > > 1) The Netbeans project is potentially loosing lots of people who > > would > > > > > have liked to contribute, but can't find a way how. > > > > > > > > the insight is good, so you obvisually went through this and could > > > > improve the documentation.
