Hi I am trying to follow the Getting Started guide for Jersey 2.0.
I did steps 1.1 and 1.2 as is. No problem there.
For step 1.3 I had a problem cause maven could not find the javax-annotation 1.2 but I solved it following the advice of another Stackoverflow user and added a repository to my pom.
Somvn clean test passes with no problems, BUT when I try to run mvn clean exec:java I get back
[WARNING] java.lang.ClassNotFoundException: com.example.Main
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)

The pom.xml is the one created by the following command:
mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=simple-service -Dpackage=com.example \
-DarchetypeVersion=2.0
where the only addition I 've made is the following:
<repositories>
<repository>
<id>java.net.repo</id>
<url>https://maven.java.net/content/groups/promoted/</url>
<layout>default</layout>
</repository>
</repositories>
In case it is of interest this is the output of mvn -version

I am able to reproduce your error. This has nothing to do with Jersey; it's an error you're making with Maven. mvn clean exec:java says: "delete all the .class files and then try to run the Main .class file". Since you deleted it, Maven can't find it. Here's a solution:
mvn clean compile exec:java
This should fix the problem in your question. This says "delete all the .class files, recompile them from source and then try to run the Main .class file"
To get past the next error you'll see, delete the <scope>test</scope> line from the client dependency in the pom.xml:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>

<scope>test</scope>

I am doing a maven build, but it gets an error related to one of the dependencies. If I (and other developers) build this on our local machines or on other linux servers, it builds with no problems. However, on one particular linux server, it gets the following error when building.
mvn clean install DskipTests=true -U
maven Build Error:

So I think there must be something different on this server that is causing the dependency error. Any ideas please?
I see it gets a java.security.InvalidAlgorithmParameterException, so this suggests that there is probably some restriction configured on the server that is preventing the dependency being downloaded to the server.

I fixed this issue. The problem was the Java version. I temporally build with Java 8 (to download the Cloudmersive api), then switched back to Java 7. Build is successful.
i been stuck with this for a while.
I am trying to automate the build and deploy (in nexus3) of several java modules and remove the need for manually set the module version in the projects pom.
My issue is that maven is ignoring the variables inside the pom files.
Parent pom:
<properties>
<revision>local</revision>
</properties>
<name>lib-cloud</name>
<groupId>com.company.lib</groupId>
<artifactId>lib-cloud</artifactId>
<version>${revision}</version>
<packaging>pom</packaging>
<modules>
<module>lib-cloud-main</module>
</modules>
and the child pom:
<properties>
<unrelatedVAR>2017.3.3</unrelatedVAR>
</properties>
<parent>
<groupId>com.company.lib</groupId>
<artifactId>lib-cloud</artifactId>
<version>${revision}</version>
</parent>
<artifactId>lib-cloud-main</artifactId>
<name>lib-cloud-main</name>
and then i build this with:
mvn -Drevision=3.1 clean package deploy
This build the code just fine, create a lib-cloud-main/target/lib-cloud-main-3.1.jar
In side the jar, i can already see that
lib-cloud-main-3.1.jar/maven/com.company.lib/lib-cloud-main/pom.xml have
<version>${revision}</version>
As version, instead 3.1 as i would expected, but still this artifact manages to be saved in nexus.
If i try to use it, however, maven trow the error when trying to get the pom:
[ERROR] Failed to execute goal on project core-backend-api: Could not resolve dependencies for project com.company.core:core-backend-api:jar:local: Failed to collect dependencies at com.company.lib:lib-cloud-main:jar:3.1: Failed to read artifact descriptor for com.company.lib:lib-cloud-main:jar:3.1: Could not transfer artifact com.company.lib:lib-cloud:pom:${revision} from/to company-maven-public (http://mvn.company.local/repository/maven-public/): Failed to transfer file: http://mvn.company.local/repository/maven-public/com/company/lib/lib-cloud/$%7Brevision%7D/lib-cloud-$%7Brevision%7D.pom. Return code is: 400 , ReasonPhrase:Invalid repository path.
I even tried to use
mvn release:update-versions -DdevelopmentVersion=3.1
As a way to overwrite the poms with a static value before the build but this methos STILL fail to touch the tag in any project children pom.
What i am doing wrong?

You should use release plugin to do this.
mvn release:update-versions -DautoVersionSubmodules=true
I'm experimenting with writing an openHab2 binding which is written in java. I'm a C++ guy and java is new to me. The offending code looks like this:
import org.apache.http.client.CredentialsProvider;
import org.apache.http.impl.client.BasicCredentialsProvider;
...
#Override
public void initialize() {
...
CredentialsProvider credsProvider = new BasicCredentialsProvider();
...
}
I added org.apache.httpcomponents.htpclient_4.5.2.v20170210-0925.jar to the buildpath as an external jar and the program builds without any problems.
This project uses Maven, which I'm not familiar with either, as the build system so I added:
<dependencies>
<dependency>
<groupId>org.apache.httpcomponent</groupId>
<artifactId>httpclient</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<scope>runtime</scope>
</dependency>
</dependencies>
to the pom.xml.
When I run the system I get this error:
2018-05-20 09:51:38.574 [ERROR] [.i.c.AbstractInvocationHandler:101 ]
- An error occurred while calling method 'ThingHandler.initialize()' on

- Exception occurred while initializing handler of thing 'testbinging:sample:0ac3dcf3':
org/apache/http/impl/client/BasicCredentialsProviderjava.lang.NoClassDefFoundError:

It look to my untrained eye like the runtime classpath is not set correctly.
I'm using eclipse-oxygen version Oxygen.3a Release(4.7.3a), Build id: 20181405.1200 and
$ mvn -version

It's because your dependencies are runtime:
<scope>runtime</scope>
You need to either change it to:
<scope>compile</scope>
Or delete the scope line, since this is the default scope.
Runtime dependencies aren't used at compile time. You can't read more about it: https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

I had the same problem, but moving back to Maven 3.0.5 solved the problem
I'm having a strange problem when trying to run a maven build that uses the jaxb2 plugin to do JAXB codegen (see stacktrace below). The best that I can figure is that there's some implementation of DTMManager that's being class loaded from a different JAR than the one in xalan-2.7.1; however, I have verified that the classpath that is used for running the jaxb:generate goal only has the one xalan-2.7.1.jar that contains a DTMManager or a DTMManagerDefault - so I have no clue what else might be getting in the way.
One final data point: our build specifies a 'snapshot' profile, which really only serves to also JAR up the sources (using maven-source-plugin) and publish them as artifacts. The failure scenario I described above only occurs when this profile is specified in addition to the default.
I'm using Maven 2.2.1 running on Sun's 64-bit JDK 1.6.0_21 on Linux x64 (Fedora 13) - see below the stacktrace for the 'mvn -v' info.
Any ideas on what the problem may be and/or how to go about debugging it? This has been causing me grief for the past few days and it's now blocking progress :(

The solution is to search for all dependencies on Xalan and xercesImpl in the classpath . These dependencies should be excluded.
Updated
I found an answer like this - see http://www.mail-archive.com/dev#qpid.apache.org/msg07295.html
Had a look at this closely and figured it was due to a classpath class
due to Sun bundling an older version of Xalan jar.
I have disabled this test until we come up with a decent solution.

To exclude the xalan and xercesImpl dependencies in Maven:
<dependency> <!-- ClassNotFoundException: org.jaxen.dom.DOMXPath -->

<version>1.1.3</version>

For me setting following JVM property worked.
