[tycho-user] Tycho 1.2.0: Materialize-product generates invalid ini file

[Jörg Schaible <joerg.schaible@xxxxxxxxxxxxxxx>]

Hi,

we have a strange effect in our build. We have two product files 
configured for the materialize-product goal of the tycho-p2-director 
plugin and support 3 OS targets.

The generated ini files for one product are correct for all target OSes, 
but the ini files for the other product are "invalid" for all OSes, e.g. 
Windows:

============ %< ===================
-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
plugins/
org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834
-nl
de
--launcher.library
/data/head/temp/products/target/products/com.bpminspire.designer/win32/
win32/x86_64/plugins/
org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834
-startup
/data/head/temp/products/target/products/com.bpminspire.designer/win32/
win32/x86_64/plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
-vmargs
-Xms512m
-Xmx1024m
--add-modules=ALL-SYSTEM
============ %< ===================

The entries for startup and launcher.library are contained twice and the 
second entries with the absolute paths from the build server clobber the 
first (correct) ones, when the application tries to start. Obviously the 
start fails.

We compared the two product files and cannot find any relevant difference.

Any idea, what causes those entries with absolute paths in the generated 
ini files?

Regards,
Jörg
