Hello all.

I've got the following problem when trying to headless build my feature:
the compiler fails with this message:

> # Eclipse Java Compiler 0.894_R34x, 3.4.2 release, Copyright IBM Corp 2000, 2008. All rights reserved.
> ----------
> 1. ERROR in C:\Users\FORGES_dev\FORGES\temp\ForgesClientAutomaticBuild\p lugins\com.airbus.forges.client.team\src\com\airbus\forges\c lient\ForgesTeamPlugin.java (at line 16)
> import com.airbus.forges.ws.model.Profile;
> ^^^^^^^^^^^^^^^^^^^^
> The import com.airbus.forges.ws cannot be resolved

My plugin breakdown is as follow :
- the "com.airbus.forges.client.team" plugin requires the
"com.airbus.forges.server.api" plugin and re-exports this dependency,
- the "com.airbus.forges.server.api" plugin exports this 3 packages :
com.airbus.forges.ws.api
com.airbus.forges.ws.model
com.airbus.forges.ws.util

My context is Eclipse 3.4.2 and the PDE build within Eclipse is successfull.

Can you help me in achieving this headless build ?
Thank you.

You can check the classpath being used for the compile by looking in the
generated com.airbus.forges.client.team/build.xml script.

One possibility is that the classpath is correct but
com.airbus.forges.server.api has not been compiled yet.

In 3.4, plugins are compiled according to the feature structure. The
features are visited depth first. The plug-ins within a given feature
are sorted according to dependencies, but this sorting does not cross
the feature boundaries.

This probably works from in the IDE because the classpath generally gets
the com.airbus.forges.server.api/bin folder as well.

You can either re-arrange your feature structure, or upgrade your
builder to 3.5 and define the property "flattenDependencies=true".
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=212467. (You may also
be interested in https://bugs.eclipse.org/bugs/show_bug.cgi?id=238177)

Note it is possible to use a 3.5 builder and still target 3.4.2 for your
release. Just use a baseLocation that is separate from the eclipse
running the build. The Eclipse SDK is currently in final release
candidates for 3.5. RC4 is here:

Thank you for your help.

After re-arranging the order of my plug-ins in the feature definition, my
headless build worked fine. I can remain with my 3.42 Eclipse release.
My IDE PDE build still works also, that's great !
