ant - CreateProcess error=206, The filename or extension is too long

Question

I'm trying to call Findbugs via Ant, but receiving this error:

Cannot run program "C:Program Files (x86)Javajre6injavaw.exe" (in 
directory "H:UsersMyNameworkspaceMyProject"): 
CreateProcess error=206, The filename or extension is too long

How can I fix this? o.O

Answer 1

I had the same problem. I used

<fileset dir="${basedir}/build">
  <include name="**/*.class"/>
</fileset>

inside findbugs target and it seems that there is too much .class files to be passed to findbug (?via command line?) because when I used

<fileset dir="${basedir}/build/com/domain/package">
  <include name="**/*.class"/>
</fileset>

that had low number of classes, the error was gone.

So, I solved the problem by making one jar file and feeding it to findbugs target with

<findbugs home="${findbugs.home}">
  ...
  <class location="${basedir}/targets/classes-to-analyze.jar"/>
</findbugs>
