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 have an Eclipse based application which is being ported from Java 8 to Java 11. Since javax.xml and friends was removed from the JDK, I had to add it as an Import-Package to every plug-in that needed them.
Now however, when run this code
Marshaller marshaller = JAXBContext.newInstance(MyClass.class).createMarshaller();
I get the following exception:
java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)
at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)
at org.eclipse.osgi.internal.framework.ContextFinder.loadClass(ContextFinder.java:135)

at javax.xml.bind.ContextFinder.safeLoadClass(ContextFinder.java:480)
at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:184)
I can add com.sun.xml.bind, which should have the dependency, but nothing happens. This is understandable, since OSGi rules prevents hacking into another plug-in via reflection.
However I cannot add Require-Bundle nor Import-Package to the JDK or the bundle around javax.xml.bind.
There is a bug surrounding this issue, but I cannot find a good solution for my application in the comments. Still I assume it can be fixed for an Eclipse application, else Eclipse itself shouldn't be able to run on Java 11.
How do I fix this exception?
We found an OSGi compatible way to fix this exception:
add the following implementations to the target platform
org.apache.servicemix.specs.jaxb-api-2.2 (from Maven central)
com.sun.xml.bind (from the Eclipse platform; this is the one that contains the ContextFactory)
make sure these bundles are started with your application
make sure the Apache bundle is started before everything else
So in Tycho, this would look like this:
<bundleStartLevel>
<bundle>
<id>org.apache.servicemix.specs.jaxb-api-2.2</id>
<autoStart>true</autoStart>
<level>1</level>
</bundle>
</bundleStartLevel>
<dependencies>
<dependency>
<artifactId>org.eclipse.e4.rcp</artifactId>
<type>eclipse-feature</type>
</dependency>
<dependency>
<type>p2-installable-unit</type>
<artifactId>org.apache.servicemix.specs.jaxb-api-2.2</artifactId>
</dependency>
<dependency>
<type>p2-installable-unit</type>
<artifactId>com.sun.xml.bind</artifactId>
</dependency>
</dependencies>
I'm too using jaxb in my application (JMSToolBox) and too migrated from Java 1.8 to Java 11 and didn't had this problem
In my plugin, I have a "lib" directory with the"jaxb-ri"jar and its dependencies (from maven):
jaxb-api-2.3.1.jar
jaxb-runtime-2.3.2.jar
javax.activation-api-1.2.0.jar
istack-commons-runtime-3.0.7.jar
Then the plugin references those jars (MANIFEST.MF + build.properties) and I don't have any problem
The plugin is here
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)
See http://wiki.eclipse.org/Tycho/Release_Notes/0.16#Improvements_and_Fixes
I am trying to add a WSDL module to my existing application, but I'm struggling to get the dependencies resolved.
According to their website, this is the correct dependency
<dependency>
<groupId>org.ow2.easywsdl</groupId>
<artifactId>easywsdl-wsdl</artifactId>
<version>2.1</version>
</dependency>
After a search (search.maven.org), I already changed the version to 2.3 and there are a bunch of files that are downloaded into my local repository, but when running the application (with the websites demo code), I bump into this error:
java.lang.ClassNotFoundException: com.ebmwebsourcing.easycommons.uri.UriManager
And I believe it has something to do with the missing artifacts :
com.ebmwebsourcing.easycommons:easycommons.uri:jar:1.1
com.ebmwebsourcing.easycommons:easycommons.logger:jar:1.1
In particular the first one. Now, I'm relatively new to using Maven... How would I go about solving this?
Thanks.
The solution is to add the petalslink repository. Appearantly the standard maven repository doesn't contain the easycommons dependency. The petalslink repository does.
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)
