I am coming across a similar kind of issue, when I use Maven-findbugs plugin.

 

Console Output:

The following classes needed for analysis were missing:
javax.servlet.http.HttpServlet

javax.servlet.GenericServlet

…………

…………

 

Is this also a bug???

 

Is this the right forum for me to discuss the issue??

An updated version of the Eclipse plugin with Jon's bugfix and various
other fixes is available at the following update site:
 
    http://findbugs.sourceforge.net/eclipsePlugin
 
You'll need to do Help->Software Updates->Find and Install
and so forth from within Eclipse.
 
I haven't had time to do a formal release, but hopefully I'll be able
to in a week or so.
 
There have been reports that the plugin does not work with Eclipse 3.1,
which we will investigate at some point.  It should work fine with
3.0.x.

It is hard to say.  FindBugs is trying to find these classes, but it is complaining
that they are not available.  Using FindBugs in command-line mode, you would
specify the jar file these classes are in (j2ee.jar?) as part of the
-auxClasspath option.  I'm not sure how this works with Maven, however.

Is this the right forum for me to discuss the issue??

If the problem is a bug in FindBugs, then yes.  If it is a problem with the maven
plugin, no.

-Dave

Which version of Maven do you use?

Do you have all of those artifacts (jars) as dependencies in the pom?

And David is right - this issue is more correct to start with on a Maven user
list, as it is probably a config issue or plugin problem.

The Maven 2 plugin experiences this problem.  I did a little investigation an found that an underlying Maven function may have a bug.
I need to do a little research to see if a bug has been reported.  I am going to check a few other plugins which need to have the same functionality and see if the have a similar issue.

Yes I do have them all. But there are certain classes of my application also missed for analysis. For example it also misses my

 

com.mycompany.app.App

com.mycompany.webapp.WebApp

com.mycompany.maven.Maven

com.mycompany.finbugs.FindBugs

 

Only some of them, not all. How could this be defined in any project pom?

 

First I thought that the issue was in my local repository as I have manually created the folder structure for certain third party jars (that are not available in the Maven remote repo) and added the jars and dependent poms in the way Maven wants (I have also defined the same artifact id and group id in my project pom xml, so no compilation issues).  Even after restructuring it still misses them all.

And I have posted this issue in Maven plugin user forum too, but I havn't got any such immediate and interactive replies. As I find Maven-Findbugs-Plugin users like Jeff in this forum, I believe I will get the needed help.

 

So this could be some bug as Garvin suggests.

 

Thanks,

Radhika

David,

I did fix the issues with the Maven 2 plugin setting the auxClasspath but the issues still persists.
Does Findbugs have any issues with spaces in the fully qualified path entry?    The default for Maven's local repository on window's systems is the %user_home%/.m2/repository which by default translates to C:\Documents and Settings\user_name\.m2\repository
