Hi
I managed to solve the problem of building with tycho in the presence of
the generated dependencies on org.hamcrest as follows:
- in the tycho pom file I add this repository (so there's no need of
using the swtbot repository):
<repository>
<id>orbit</id>
<layout>p2</layout>
<url>http://download.eclipse.org/tools/orbit/downloads/drops/R20110523182458/repository/</url>
</repository>
- this however is not enough... I don't know whether it is a tycho
thing, but it cannot resolve org.hamcrest (and download it) if it is
just an imported package: I have to add org.hamcrest as a required
bundle in the MANIFEST.MF, thus
Require-Bundle: ...
org.eclipse.core.runtime,
org.eclipse.xtext.junit4,
org.junit4,
org.eclipse.ui.workbench;resolution:=optional,
org.eclipse.xtext.xbase.junit;bundle-version="2.3.0",
org.eclipse.xtext.xbase;bundle-version="2.3.0",
org.eclipse.jdt.core;bundle-version="3.7.3",
org.hamcrest <---------- MANUALLY ADDED
Import-Package: org.apache.commons.logging,
org.apache.log4j,
org.junit;version="4.5.0",
org.junit.runner;version="4.5.0",
org.junit.runner.manipulation;version="4.5.0",
org.junit.runner.notification;version="4.5.0",
org.junit.runners;version="4.5.0",
org.junit.runners.model;version="4.5.0",
org.hamcrest,
org.hamcrest.core
is this a bug? would it do harm to generate in the MANIFEST.MF of the
test plugin also org.hamcrest as required bundle (besides as an imported
package)?
cheers
Lorenzo

Hi Lorenzo,
I think we fixed an issue in the unit test generator fragment that added
the package import for org.harmcrest by accident. Only
org.harmcrest.core is requrired (or the other way round - anyway, only
one of both imports was valid where the other one cause issues). Could
you please try with the latest nightlies?
Regards,
Sebastian

Hi Sebastian
I tried
http://download.eclipse.org/modeling/tmf/xtext/updates/composite/latest/
i.e., 2.3.0.v201205191342 and I still get this MANIFEST.MF for the test
plugin, which shows the same problem (which, again, can be fixed by
adding org.hamcrest as a Require-Bundle and not just Import-Package):
Require-Bundle: org.xtext.example.mydsl,
org.xtext.example.mydsl.ui,
org.eclipse.core.runtime,
org.eclipse.xtext.junit4,
org.junit4,
org.eclipse.ui.workbench;resolution:=optional,
org.eclipse.xtext.xbase.junit;bundle-version="2.3.0",
org.eclipse.xtext.xbase;bundle-version="2.3.0",
org.eclipse.jdt.core;bundle-version="3.7.3"
Import-Package: org.apache.commons.logging,
org.apache.log4j,
org.junit;version="4.5.0",
org.junit.runner;version="4.5.0",
org.junit.runner.manipulation;version="4.5.0",
org.junit.runner.notification;version="4.5.0",
org.junit.runners;version="4.5.0",
org.junit.runners.model;version="4.5.0",
org.hamcrest,
org.hamcrest.core

Hi Lorenzo,
this bug was fixed on 15.05, so your version v20120519 contains the fix already, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=379521
I've tried both wizard and generator with the most recent version 2.3.0.v201205201426 and all works as expected. Only the org.hamcrest.core package import is generated.
Best regards,
Dennis.
P.S.: You can't import org.hamcrest package because it's hidden/protected, see the bug report for more information.

Hi Dennis
sorry I hadn't realized my workspace was using a target platform based
on xtext 2.3.0M7 so I wasn't actually using the latest generator :)
with the current 2.3.0.v201205210926 the generated MANIFEST.MF for the
test plugin is
Require-Bundle: org.xtext.example.mydsl,
org.xtext.example.mydsl.ui,
org.eclipse.core.runtime,
org.eclipse.xtext.junit4,
org.junit4,
org.eclipse.ui.workbench;resolution:=optional,
org.eclipse.xtext.xbase.junit;bundle-version="2.3.0",
org.eclipse.xtext.xbase;bundle-version="2.3.0",
org.eclipse.jdt.core;bundle-version="3.7.3"
Import-Package: org.apache.commons.logging,
org.apache.log4j,
org.junit.runner;version="4.5.0",
org.junit.runner.manipulation;version="4.5.0",
org.junit.runner.notification;version="4.5.0",
org.junit.runners;version="4.5.0",
org.junit.runners.model;version="4.5.0",
org.hamcrest.core
which keeps Tycho happy :)
thanks
Lorenzo
