Is there a Maven plugin for the Java debugger (jdb)?
I'd like to run jdb over some of my classes in a Maven project. Is there a
plugin I can drop into my pom.xml?

You could run it via the maven-exec-plugin, which allows you to pass down the classpath.

Thanks! I'll look into it!

Hi Andrew,
Another option is to use the exec-maven-plugin to launch your java program
of choice, then attach to it with jdb afterward using the "-attach" option.

For Eclipse (my preferred tool): http://eclim.org/
I know people who use it to good effect, but personally I don't use it. I
prefer the opposite approach: embedding vim editing style into Eclipse:
http://vrapper.sourceforge.net/home/
Vim and Eclipse both bring so much productivity I would hate to give up
either of them. Fortunately, you don't have to. :-)

RE: Is there a Maven plugin for the Java debugger (jdb)?
Posted by "Sankaran, Nambi" <ns...@ebay.com>.
A lot of developers are asking for simplicity of java development.
Especially folks who code in other languages such as python, view java as heavy weight because of IDEs.
It takes a while to master IDEs, without IDEs java is not a productive environment.
I used to do Java development using CLI, but after I got used to IDEs development was a lot easier.
IDEs do bring a lot of value .
So, why not bring the nice features of IDEs into editors such as emacs or vim.
Debugging is one of the important features that is easy to do in IDE, but hard to do in CLI using jdb.
If there is a way (plugin) that can enable this for emacs or vim, would be a great.

Why would you want to walk from New York to San Francisco when you can fly?
Some people are gluttons for punishment, some people like text-mode (works
better over plain ssh without resorting to eg X11 forwarding)
Finally debugging when the debugger and debugged process are on the same
machine rather than separated by a 150ms latency link is a lot nicer... And
sadly cli tools are the only way to handle that without adding significant
lag.
Having said all that, debuggers are the tool of last resort, if you need to
use them you start worrying about heisenbugs etc.
A good log file beats the pants off a debugger 99 times out of 100... Ask
anyone who tried to figure out why the conference call talker indicators
were invalid or did work on any real time system and they will swear by a
good log file with mapped diagnostic context support.
Me... I worked on real time conferencing systems, so a good log file is
what I favour, you can't single step debug a real time teleconference ;-)
the skills you learn trying figure out techniques to debug such systems are
very valuable

I'm sorry; I don't understand. Why would you want to use a text editor, rather than an IDE, to debug a java program?

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Andrew Pennebaker <ap...@42six.com>.
Ah, forgot to add the full namespace to the main class. This works:
$ cat pom.xml
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<configuration>
<executable>jdb</executable>
<arguments>
<argument>-classpath</argument>
<classpath />
<argument>${jdb}</argument>
</arguments>
</configuration>
<executions>
<execution>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
</plugin>
...
$ mvn -Djdb=com.my.stuff.HelloWorld exec:exec
run

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Curtis Rueden <ct...@wisc.edu>.
Hi Andrew,
> Exception occurred: java.lang.ClassNotFoundException

Not sure what to tell you. I tested it with my project and was able to
launch my app from jdb as usual; see:
https://github.com/imagej/imagej/commit/8cfe0fde7d89c71e083c992f5c7432b29f09c483
> Are we sure the <argument>-classpath</argument><classpath /> bit is

Yep, at least on my OS X system with Sun Java 1.7.0_21:
$ jdb -version
This is jdb version 1.6 (Java SE version 1.7.0_21)
$ jdb -help | grep classpath
-classpath <directories separated by ":">
Is your "HelloMaven" class really in the default package? What happens if
you change "jdb" to "java" in your exec; can you launch your application in
non-debug mode that way? If not, there is something fishy with either your
java main class or your classpath.
Regards,
Curtis

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Andrew Pennebaker <ap...@42six.com>.
So close! I added the snippet inside my
<build><plugins>...</plugins></build> in pom.xml. Thanks for supplying the
exact code, by the way!
But jdb is showing an error:
$ mvn exec:exec -Djdb.mainClass=HelloMaven
Initializing jdb ...
> run
run HelloMaven
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
>
VM Started:
Exception occurred: java.lang.ClassNotFoundException
(uncaught)"thread=main", java.net.URLClassLoader$1.run(), line=202 bci=73
main[1]
This happens for any class I hand exec:exec.
This is the same error I see if I try to jdb <Class> manually.
Are we sure the <argument>-classpath</argument><classpath /> bit is the
correct way to hand jdb the CLASSPATH?

We can get close. If you use the block above, you would launch with:
mvn -Djdb.mainClass=<Class> exec:exec
Where "jdb.mainClass" is the property used in the XML above. And if that is
not concise enough for your taste you can choose a property with a shorter
name.
Working example inside a profile with a specific main class is here:

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Andrew Pennebaker <ap...@42six.com>.
Thank you, Curtis, that looks like an excellent suggestion!
Could you elaborate on the exact <plugin>...</plugin> snippet I would need
to drop into my pom.xml in order to achieve this?
If I could just `mvn exec:exec <Class>`, starting a jdb session on
<Class>.main(), that would be *perfect*.

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Curtis Rueden <ct...@wisc.edu>.
Hi all,
Rather than getting into an eclipse vs. vim vs. emacs flamewar, I'd rather
just ask: Andrew, did you try attaching your jdb to a running java instance
launched via exec-maven-plugin as I suggested yet?
You can configure exec-maven-plugin in your pom so that launching the
compatible java process is as easy as "mvn exec:exec". You could even
specify jdb as the executable directly if that's what you want and then you
wouldn't even need the attachment step. Using profiles (yes, this is one of
their benign uses!) you can even set up multiple different behaviors of
exec:exec for different common situations. Really I don't think there is
any need whatsoever for a dedicated "mvn exec:jdb" here.

Re: Is there a Maven plugin for the Java debugger (jdb)?
Posted by Andrew Pennebaker <ap...@42six.com>.
Why would anyone want to do this? So we don't have to debug Maven projects
with Eclipse/IntelliJ, but the text editor of our choice. This is best
accomplished by Maven tasks which interact with the command line jdb tool.

RE: Is there a Maven plugin for the Java debugger (jdb)?
Posted by "Sankaran, Nambi" <ns...@ebay.com>.
That is very interesting.
It may be hard, because the line numbers in java byte code needs to associated with the lines numbers in the source file.
However, It may be possible to do that in emacs and vim.

Yes, various Java IDEs can debug Java code, including Java code organized in Maven projects. What I'm interested in is debugging Java code in a Maven project with an arbitrary text editor, not necessarily Eclipse or Intellij, for example Emacs, or even Notepad, by invoking Maven tasks that point to Maven plugins that interact with jdb.

It very is easy to debug maven from eclipse, I have documented how I debug maven-jetty-plugin using eclipse

I could also use an IDE for package management, but I'd rather use plain Maven and an arbitrary text editor instead.

Re: Is there a Maven plugin for the Java debugger (jdb)?

The simplest way to do this is actually to run it in your IDE directly. IntellijIDEA community edition can import your maven project and thus get all of the dependencies. Then you just run the program in the debugger. I presume Eclipse can do something similar.

Yes. I'm looking for a task like `mvn jdb:debug <Class>` that starts a jdb
session on <Class>.main().
I can run jdb on individual Java code outside of a Maven structure, but I'm
not sure how to inform jdb of Java code in a Maven project, Maven's
CLASSPATH handling, etc. etc.

What would that mean? Do you want to execute the program in the debugger?
