Hello,

When doing a Tycho build, Tycho stumbles over one my test plugins, throwing a no NoClassDefFoundError over javafx/collections/FXCollections, as follows :

Quote:

Running be.groups.portfolio.service.codelist.CodelistItemsTest

Needless to say, I have neither compiling issues nor problems to launch the tests from inside the IDE.

I have no idea where as to look for this problem, any ideas ... ?

So what version of java is the build running on? Is it running on the
same computer you develop? e.g. when you run the build on a linux server
make sure you run with OracleJDK and/or an OpenJDK you downloaded
yourself because the stock one from linux distros does not holds JavaFX

The build runs on my personal computer (Windows 7), no server is involved.

I tried with both Java 8_40 and 8_31, with the same issue.

Oh the test fails because our OSGi hook is not loaded! I need to did up how we made Jenny happy - you to add some extra code to your pom

I added the following configuration for the classloader hook in the tycho surefire test plugin, but that doesn't change anything :

<plugin>
		        <groupId>org.eclipse.tycho</groupId>
		        <artifactId>tycho-surefire-plugin</artifactId>
		        <version>${tycho-version}</version>
		        <executions>
		          <execution>
		            <id>JUnitTest</id>
		            <goals>
		              <goal>test</goal>
		            </goals>
		            <!-- <phase>install</phase>-->
		            <configuration>
		              <!--<useSystemClassLoader>false</useSystemClassLoader>-->
		              <useUIHarness>true</useUIHarness>
		              <useUIThread>true</useUIThread>
		            <extraClasspathElements>

						</extraClasspathElements>
		            </configuration>
		          </execution>
		        </executions>
		      </plugin>

I also tried adding the VM_Argument -"Dosgi.framework.extensions=org.eclipse.fx.osgi" to the run configuration of the Maven build... Without success either.

The important part is the framework-extensions stuff

Unfortunately adding this (stripping of the Jemmy specifics) doesn't work either. I get a PluginExecutionException:

Quote:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.22.0:test (default) on project be.groups.portfolio.service.codelistprovider.test: Execution default of goal org.eclipse.tycho:tycho-surefire-plugin:0.22.0:test failed:

Maven's error message is a bit cryptic : any idea what this means? Googling it up is not of any help...

You better ask at the tycho mailing list. As I'm not really a
tycho/maven expert. How does you pom.xml look like now? Did you by
chance forget to modify the packing type is should be
<packaging>eclipse-test-plugin</packaging>?

Hello,

I went for advice to the Tycho mailing list and the problem was the test goal : leaving the goal unspecified (with default goal integration test) solves this problem (cf. bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=440094).

I have, however, another problem now, for which the mailing list couldn't give an answer: Tycho cannot find the framework extension org.eclipse.fx.osgi :

Quote:

Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.22.0:test (default-test) on project be.groups.portfolio.service.codelistprovider.test: Failed to resolve framework extension org.eclipse.fx.runtime:org.eclipse.fx.osgi:jar: Missing:

The POM of my test plugin looks like this now :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

The commented areas can be toggled on or off without impacting the error.
Do I need something more to make the extension work... ?

Could it be that the fragment has to be installed into your local maven
repo? I will touch this area once I've managed to get TestFX through the
IP chain which unfortunately takes for a freaking long time because the
IP team is swapped with work.

Hello,

Just in case some-one would have the same issue : following the instruction mvn install:install-file -DgroupId=org.eclipse.fx.runtime -DartifactId=org.eclipse.fx.osgi -Dversion=0.0.0 -Dpackaging=jar -Dfile=/path/to/file works very nicely.

I also tried bypassing the local Nexus server and fetch directly from Maven central, no success either.

Hi,

The other option is that you start kicking out the "org.eclipse.fx.osgi"
by reconfiguring Equinox to consult the ext-classpath.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=462634
