Hi

first of all, I don't have a Mac, but I know many of you have one so you
could probably help me with UI tests failure on Mac, for one of my Xtext
project, https://github.com/LorenzoBettini/jbase (I already set
-XstartOnFirstThread when running on Mac)

A user reported UI tests failures on Mac,
https://github.com/LorenzoBettini/jbase/issues/3. The UI tests concern
content assist, workbench integration, and variable extract refactoring.

The tests that fail need the Java classpath. On the issue the complete
failure is reported, but the suspicious parts can be summarized:

ERRORS OMITTED: The type <JRE type> cannot be resolved. It is indirectly
referenced from required .class files...

java.lang.AssertionError: No such proposal: toString Found:

Loading target platform... DONE.
org.eclipse.jdt.internal.compiler.problem.AbortCompilation: Pb(324) The
type java.lang.Object cannot be resolved. It is indirectly referenced
from required .class files

Unbound classpath container: 'JRE System Library [JavaSE-1.6]' in
project 'TestProject'
The project cannot be built until build path errors are resolved
Couldn't resolve reference to JvmType 'String'.

So I guess that JRE is not picked when running UI tests. Surefire also
reports this message

objc[881]: Class JavaLaunchHelper is implemented in both
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/bin/java
and
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/lib/libinstrument.dylib.
One of the two will be used. Which one is undefined.

are there any special installation configurations for Java on Mac?

many thanks in advance
Lorenzo

did you set the -XstartOnFirstThread https://wiki.eclipse.org/Tycho/FAQ
but your problem seems different.

looks like jdt.launching.osx* is missing on the classpath

adding a dependeny to org.eclipse.jdt.launching.macosx gives an error that it is not available.
looks like the target platform config is messed up.

https://dev.eclipse.org/mhonarc/lists/tycho-user/msg06622.html
mentions a similar problem but has no solution for it

adding the plugin explicitely to the target file gives

Caused by: java.lang.IllegalStateException: org.eclipse.jdt.launching.macosx 3.3.0.v20150313-0517 cannot be installed in this environment because its filter is not applicable.
at org.eclipse.equinox.internal.p2.director.Slicer.validateInput(Slicer.java:106)
at org.eclipse.equinox.internal.p2.director.Slicer.slice(Slicer.java:57)
at org.eclipse.tycho.p2.util.resolution.AbstractSlicerResolutionStrategy.slice(AbstractSlicerResolutionStrategy.java:76)
... 29 more

(in my projects i always build against a binary built target)

i have no idea on how to fix this.
maybe the tycho mailing list is a better place to ask

Hi

what do you mean by "binary built target"?

I thought the error might be due to this info

objc[881]: Class JavaLaunchHelper is implemented in both
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/bin/java
and
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre/lib/libinstrument.dylib.
One of the two will be used. Which one is undefined.

Do you have a JRE or a JDK on your machine?

thanks in advance
Lorenzo

the following worked for me

- adapt the target-plaform-configuration places

<plugin>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>target-platform-configuration</artifactId>
				<configuration>
					<environments>
          			</environments>
					<dependency-resolution>
						<extraRequirements>
							<!-- to get the org.eclipse.osgi.compatibility.state plugin iff 
							the targeted Eclipse version (e.g., Luna) has it
							(backwards compatible with kepler and previous versions) -->
							<requirement>
								<type>eclipse-feature</type>
								<id>org.eclipse.rcp</id>
								<versionRange>0.0.0</versionRange>
							</requirement>
							
						</extraRequirements>
					</dependency-resolution>
				</configuration>
			</plugin>

and add the explict dependency to the manifest

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: jbase.tests
Bundle-Vendor: Lorenzo Bettini
Bundle-Version: 0.1.0.qualifier
Bundle-SymbolicName: jbase.tests; singleton:=true
Bundle-ActivationPolicy: lazy
Require-Bundle: jbase,
 jbase.ui,
 org.eclipse.core.runtime,
 org.eclipse.xtext.junit4,
 org.eclipse.xtext.xbase.lib,
 org.eclipse.ui.workbench;resolution:=optional,
 org.objectweb.asm;bundle-version="[5.0.1,6.0.0)";resolution:=optional,
 org.eclipse.xtext.xbase.junit,
 org.eclipse.jdt.core,
 org.eclipse.jdt.launching.macosx;resolution:=optional,
 jbase.testlanguage.tests,
 org.eclipse.xtext.common.types.ui,
 org.eclipse.ui.ide,
 org.eclipse.pde.core;bundle-version="3.10.101"
Import-Package: 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.core
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Export-Package: jbase,
 jbase

still the question why this does not happen automagically (tycho bug?)

This is already specified in the pom.xml of the tests plugin...
do you mean this has to be specified somewhere else?

Does it work also with this dependency?

org.eclipse.jdt.launching

i.e., the one that does not depend on the operating system?

I saw your pull request https://github.com/LorenzoBettini/jbase/pull/9
(the job for pull request fails, but that's due to my experiment for
using MacOSX build in Travis; this fails for other reasons)

But in your pull request I don't see the changes you mention: the only
commit of the pull request,
https://github.com/cdietrich/jbase/commit/edc4206fb747f7134861a2a39ccfac3b1cd1d912
, is the one which removes the <environment> specifications which I had
recently pushed... is that removal crucial for making it work?

thanks again
Lorenzo

no unfortunately not. thus i made the dependency optional in my pullreq.
(seems the git add missed the adoptions to the manifest)

and yes: it is not working if i list the environments explicitely

i found another solution

<plugin>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>target-platform-configuration</artifactId>
				<configuration>
					<dependency-resolution>
						<extraRequirements>
							<!-- to get the org.eclipse.osgi.compatibility.state plugin iff 
							the targeted Eclipse version (e.g., Luna) has it
							(backwards compatible with kepler and previous versions) -->
							<requirement>
								<type>eclipse-feature</type>
								<id>org.eclipse.rcp</id>
								<versionRange>0.0.0</versionRange>
							</requirement>
							<requirement>
								<type>eclipse-feature</type>
								<id>org.eclipse.jdt</id>
								<versionRange>0.0.0</versionRange>
							</requirement>
						</extraRequirements>
					</dependency-resolution>
				</configuration>
			</plugin>

Thank you Christian!
This really solves the problem :)
Apparently, org.eclipse.jdt feature drags in also jdt.launching.macosx
(even in Linux).

cheers
