[tycho-user] Setting target-platform-configuration <environments> causes

[Andreas Sewe <andreas.sewe@xxxxxxxxxxxxxx>]

Hi,

I followed the advise in [1] to get rid of this warning:
 > [WARNING] No explicit target runtime environment configuration. Build
is platform dependent.

Unfortunately, adding <environments> to my target-platform-configuration
causes a failure further down the line when running my tests under OS X:

> [INFO] --- tycho-surefire-plugin:0.24.0:test (default-test) @ org.eclipse.recommenders.completion.rcp.tests ---
> [INFO] {osgi.os=win32, osgi.ws=win32, org.eclipse.update.install.features=true, osgi.arch=x86}
> [ERROR] Cannot resolve project dependencies:
> [ERROR]   You requested to install 'bundle org.eclipse.jdt.launching.macosx 0.0.0' but it could not be found
> [ERROR] 
> [ERROR] See http://wiki.eclipse.org/Tycho/Dependency_Resolution_Troubleshooting for help.

FYI, the tests' pom.xml contains the following:

>  <build>
>   <plugins>
>    <plugin>
>     <groupId>org.eclipse.tycho</groupId>
>     <artifactId>tycho-surefire-plugin</artifactId>

Can someone please explain to me what's going on here? Why is Tycho
using the win32 environment (in which org.eclipse.jdt.launching.macosx
of course cannot be found)?

Best wishes,

Andreas
