Headless build: The type X is already defined [message #487983]

Hello all,

It's been a while i am trying to make a nightly build of my RCP application,
but when I run the pde-build ant task, the pde runs well at the begining,
and then fails with errors like :
"The type [type] is already defined"

I've found a bug for this :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=146324

But it seems to be closed. At the end someone say the problem had nothing to
do with Eclipse but didn't post what was the problem. In my situation,
everything compile fine with the UI compiler.

Thank you very much for your help,
Christophe.

Is it possible that the error is real?

One thing I could imagine is if you had 2 source files defining the same
type, and in the workspace, one of those is filtered out with exclusions
on the source folder. The headless build does not have access to the
workspace and does not currently support exclusions on the source folder.

Hello and thank you for your reply,

Nop this compilation error is not real. I got this error for many files of
this plugin, each of these file only exists one time and is not filtered
through some project settings for the "UI" compilation.
But the first error raised is on a class implementing the interface ICommand
(this interface comes from my code). The eclipse core components also
defines an interface named ICommand (but, of course, in another package and
plugin). Could there be problems ?

For example, for the first class on which I get this error, here is the
sequence of output from ant referencing this file :
[java] [javac] [parsing
F:\tmp\build\plugins\com.neXtep.designer.installer\src\com\n extep\installer\impl\DatabaseCommand.java

[java] [javac] ^^^^^^^^^^^^^^^

[java] [javac] ----------

Everything comes from the same plugin compilation inside a @dot: element.
I am out of ideas of what to try, what to test or what to check to
understand what is going on.

Thank you very much,
Christophe.
