I try to run tycho in ubuntu, but I face this error.
Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.14.1:build-qualifier (default-build-qualifier) on project tychodemo.bundle: Execution default-build-qualifier of goal org.eclipse.tycho:tycho-packaging-plugin:0.14.1:build-qualifier failed: Unable to load the mojo 'build-qualifier' in the plugin 'org.eclipse.tycho:tycho-packaging-plugin:0.14.1'. A required class is missing: org.eclipse.tycho.core.TychoProject
I guess it's related to my framework, because I do the same in another computer and tycho run succesfully.Can you detect my problem?
thanks in advance!
Class loader errors for Tycho classes are typically caused by mixing multiple Tycho versions in the same reactor. Being a build build extension, there must only be one version of Tycho active at a time.
To do this, check that your reactor uses the same version for the Tycho build extension and the Tycho plug-ins, e.g. by using the variable ${tycho-version} as version and defining that version in your parent POM:
<properties>
<tycho-version>0.14.1</tycho-version>
</properties>
Also make sure that all your modules reference the same parent POM, and not an older version of the POM.

All of a sudden all my Mule Maven projects are throwing this error when running mvn clean test:
java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException
at org.mule.tck.junit4.AbstractMuleTestCase.(AbstractMuleTestCase.java:71)
I can add a dependency for it, but I shoudln't really have to.
Nothings changed in my code. I am using Mule 3.4
You need commons-cli.jar in your classpath, add this Maven dependency to your pom
<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<version>1.1</version>
</dependency>
Update: OP's code was fixed after adding commons-cli 1.1 dependency.
Issue description and how to fix it: http://ricston.com/blog/mule-classnotfoundexception-tests-commons-cli/
In a nutshell, you probably have an incorrect JAR named commons-cli-1.2. Delete that and rerun your maven build. You should be good after that.
If the follogin dependency in available in the POM. it should be working fine.
<dependency>
<groupId>org.mule.tests</groupId>
<artifactId>mule-tests-functional</artifactId>
<version>3.4.0</version>
<scope>test</scope>
</dependency>
Then use mvn clean compile to update the dependency.
mvn eclipse:clean eclipse:eclipse clean compile
Hope this helps.
Maven behaviour isn't reproducible from one run to the next: apart from generic network problems and repository corruption problems, anything might be updated automatically at any time, breaking any step of the execution, even if you don't change any of your files.
Your error message about a class in some Apache Commons library suggests a disagreement between the version of that library Mule should be using (one that has the ParseException class) and the library version it actually loads (without the class and causing the exception).
Plausible version mismatch scenarios include an update to a buggy new version of Mule (maybe only to a wrong or corrupted POM) which specifies an incompatible library version, or a random upgrade or downgrade of the latest library version in your repository as a consequence of adding or updating something unrelated to Mule.
Analysis suggestions:
What plugins in your Maven repository have a snapshot version? Which ones of these snapshots were updated around the time the error first appeared?
Which library jars, and which versions, include the ParseException class? What depends on specific versions or on the latest version of those jars?
I am having an issue running tests using tycho due to an incorrect dependency resolution that, somehow, is placing the the old Google Collections .jar on the classpath and not the Guava one, despite the fact that at no point in any of my poms do I specify a dependency on collections (only guava).
My unit tests fail due to things like NoSuchMethodError (ImmutableList.copyOf), NoClassDefFoundError (Joiner), which I pretty much narrowed down to 'finding the wrong jar'. These same tests pass when ran manually in Eclipse.
Here is the relevant part of the pom:
<dependencies>
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>14.0.1</version>
</dependency>
...
</dependencies>
The phrase 'google collections' appears no where. The only other repository I specify is:
<repositories>
<repository>
<id>helios</id>
<layout>p2</layout>
<url>http://download.eclipse.org/releases/helios</url>
</repository>
</repositories>
My plugin imports 'com.google.common.base' and 'com.google.common.collect' as imported packages. I have my own bundled version of Guava 14 in my workspace for debugging, but in the POM I elect to not use my local module.
I followed Sean Patrick Floyd's answer on this question (JUnit throws java.lang.NoSuchMethodError For com.google.common.collect.Iterables.tryFind), and had my test throw an exception with the location of the .jar that the Iterables class was loaded from. It spat back out:
java.lang.IllegalArgumentException: file:/C:/Documents and Settings/Erika Redmark/.m2/repository/p2/osgi/bundle/com.google.collect/0.8.0.v201102150722/com.google.collect-0.8.0.v201102150722.jar
This is where I am now stuck. This google-collections jar is coming seemingly out of no where, and I don't know how to stop it. As long as it is being resolved, my unit tests will fail. How can I stop Tycho from trying to get the old Google Collections?
Just to clarify, this has not stopped building and deployment; the plugin update site is on an CI platform and we have been able to install the plugin on different Eclipse IDEs, so this issue is only affecting the tests.
Please let me know if additional information is needed.
The plug-in com.google.collect 0.8.0.v201102150722 is part of the Helios p2 repository that you have configured in your POM. This means that this plug-in is part of the target platform and so may be used to resolve dependencies.
If you want to ensure that the bundle is not used, make sure that it is not part of the target platform. In your case, the easiest way to do this is to explicitly remove the plug-in from the target platform:
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho-version}</version>
<configuration>
<filters>
<filter>
<type>eclipse-plugin</type>
<id>com.google.collect</id>
<removeAll />
</filter>
</filters>
</configuration>
</plugin>
Next, you need to make sure that the guava plug-in is part of the target platform. You can add an artifact from a Maven repository to the target platform in the following way:
Declare a Maven dependency to the artifact in the dependencies section of the POM. You already have done this correctly.
Set the configuration parameter <pomDependencies> to consider on Tycho's target-platform-configuration plug-in.
Note that this will generally only work if the referenced artifact is already an OSGi bundle. This is the case here: com.google.guava:guava:14.0.1 seems to have all manifest headers needed by OSGi.
This should give you the result you wanted: In the test runtime, guava should now be used to match your com.google.common.* package imports.
And another general remark on declaring dependencies in Tycho: In Tycho, you can only declare dependencies in the PDE source files META-INF/MANIFEST.MF, feature.xml, etc.
The normal Maven-style dependencies declared in the POM do not add dependencies to the project. As explained above, the POM dependencies may only add artifacts to the target platform, i.e. the set of artifacts that may be used by Tycho to resolve the dependencies declared in the PDE source files. So in the end, the POM dependency may become part of the resolved dependencies, but only if the dependency resolver picks it for matching one of the declared dependencies.
by default, tycho will add any p2 artifacts you installed in your local maven repo to the target platform. If bundle com.google.collect exports the package which you import, it may be wired.
To stop tycho from including any locally installed artifacts, you can use -Dtycho.localArtifacts=ignore (or, remove the unwanted bundle from your local maven repo)

We have our project build using maven. We try to run our unit test cases in maven build itself and for doing that we need to add DB2 driver jar in the dependency of all the sub projects.
Instead of doing that, we need a solution to specify the absolute path of the jar file as a mvn command line argument to use it in the running of unit test cases.
This is because the driver jar is available in our app server lib folder and we don't want to specify it in the dependencies of our projects.
Couldn't find a suitable solution googling it, hence requesting for an expert solution here.
Any workaround would be of greater help.
Thanks in advance.
The usual way would be to add a dependency to the database driver and limit the dependency to testing (test scope). So the library is available for unit tests but will not deployed and jar'ed.
Practically spoken, I'd create a maven artifact for this driver (just a basic POM file) and place it on the build servers maven repository (or the nexus, if you use it for the projects).
I'm using a dependency with scope set to 'system' to reference a jar that is available in the container but not in any maven repository. In this case the jar is put in a folder named 'lib' in the project like this, :
<dependency>
<groupId>groupId</groupId>
<artifactId>artifactId</artifactId>
<version>version</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/library.jar</systemPath>
</dependency>
The groupId, artifactId and version can be set to any value you want, the trick was that system dependencies have to be given with an absolute path, which is worked around by using the project.basedir property. It should also be possible to specify the complete path as a property.
We have our project build using maven. We try to run our unit test cases in maven build itself and for doing that we need to add DB2 driver jar in the dependency of all the sub projects.
Well, the maven way would be to declare the DB2 driver as dependency with a test scope in a parent project.
Instead of doing that, we need a solution to specify the absolute path of the jar file as a mvn command line argument to use it in the running of unit test cases.
You could use the additionalClasspathElement in the plugin configuration to pass the path to the driver:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<additionalClasspathElements>
<additionalClasspathElement>path/to/additional/resources</additionalClasspathElement>
</additionalClasspathElements>
</configuration>
</plugin>
If you variablelize it, you could pass the value on the command line.
But to be honest, I can't understand why you don't install the driver in a corporate repository and declare it as dependency. And if you don't have a corporate repository, use a file based repo as described in this previous answer (please, don't use the system scope bad practice). There is no good reason to go the hacky way.
We've just recently converted our project to using Maven for builds and dependency management, and after the conversion I'm getting the following exception while trying to run any JSFUnit tests in my project.
Exception class=[java.lang.UnsupportedOperationException]
com.gargoylesoftware.htmlunit.ScriptException: CSSRule com.steadystate.css.dom.CSSCharsetRuleImpl is not yet supported.
at com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine$HtmlUnitContextAction.run(JavaScriptEngine.java:527)
at net.sourceforge.htmlunit.corejs.javascript.Context.call(Context.java:537)
...
All the dependencies and JARs for JSFUnit were pulled with Maven using the JBoss repository (http://repository.jboss.com/maven2/).
We're using the following dependencies in the project:
jboss-jsfunit-core 1.2.0.Final
jboss-jsfunit-richfaces 1.2.0.Final
richfaces-ui 3.3.2.GA
openfaces 2.0
JSF 1.2_12
Facelets 1.1.14
Before the dependencies were being managed by Maven, we were able to run our JSFUnit tests just fine. I was able to semi-fix the issue by using a ss_css2.jar file that someone had tucked into our WEB-INF/lib directory (from before the Maven conversion). I'm hoping to find out if there's something else I can do to fix the dependencies in Maven rather than resorting to managing some of the dependencies myself.
You're very likely getting an "incompatible" version of HtmlUnit or another JAR (pulled transitively). Try with the version you were using previously and declare it under the dependencyManagement section, e.g.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>2.7</version><!-- put "your" version here -->
</dependency>
</dependencies>
</dependencyManagement>
Or, if you changed any version, try to revert to the exact previous state (by the way, could you clarify the differences between the previous versions and the one currently used?).
Update: It appears that the problem was related to the version of the cssparser artifact. I hadn't all the required elements to figure this out but the OP did :)
I changed the version from jFreeChart in the pom.xml of my maven project from 1.0.12 to 1.0.13.
Now I get the error
"The type org.jfree.ui.layer cannot be resolved to a type. It is indirectly referenced from required class files."
What does this mean? I just updated the jfreechart dependency.
The type is in the JCommons library. I think the problem is that the JFreeChart has not been properly distributed to maven in version 1.0.13. In the IBiblio directory listing, you can see that a .pom file is missing (as opposed to version 1.0.12, where it's present).
This means that maven has no ideas what the dependencies are. It still downloads the artifact through it's filename by convention, but it doesn't know anything about the context.
Now you can either complain to the vendor and demand a proper pom or create your own pom file (start with the old version and adjust it until things start working) and deploy it to your company's repository (or your local repository) using install:install-file or deploy:deploy-file.
My guess is that you'll at least have to include the following dependency
<dependency>
<groupId>jfree</groupId>
<artifactId>jcommon</artifactId>
<version>1.0.15</version>
</dependency>
(If you want to do it the easy way, just add the above dependency to your own project pom)
