I have been following the hibernate tutorial on http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/tutorial.html
and as others have pointed out in various web boards, it's incomplete.
When I run this command:
mvn exec:java -Dexec.mainClass="org.hibernate.tutorial.EventManager" -Dexec.args="store"

So I think the problem is obvious. When maven executes java, java doesn't know where to find my 'EventManager'. I tried the following on my command line:
set CLASSPATH=C:\Users\robe\Documents\hibernate\project1\src\main\java\org
What else could be wrong here?
Thanks!
I think your classpath is wrong. Try
set CLASSPATH=C:\Users\robe\Documents\hibernate\project1\src\main\java
You don't need the org. That is part of the full qualified class name. The full class name is org.hibernate.tutorial.EventManager
I am not familiar with this tutorial's problem. You may get other classpath errors. If you do you can add more to the class path by separating them by a semi colon.
Also you are setting the classpath in the cmd line. It will only be set for that session so you will have to run your mavem command in the same one. Or set it in your global environment variables
Try running:
mvn clean install
I know it sounds obvious, but when I tried to execute
mvn exec:java -Dexec.mainClass="org.hibernate.tutorial.EventManager" -Dexec.args="store"
I get the same error as you did. But after running mvn clean install the app started (I ran clean install for this code https://github.com/stivlo/hibernate-tutorial, it looks it is the same thing)

I'm attempting to run the sample project from How to setup akka persistence project : https://developer.lightbend.com/start/?group=akka&project=akka-samples-persistence-dc-java

Looking at the project source:
The package sample.persistence.multidc.ThumbsUpApp does not appear to exist. How to include the missing package sample.persistence.multidc.ThumbsUpApp ? Shouldn't this project execute without adding additional src code ?
It seems you are referencing a class name that doesn't exist in the project source.
You may use the following command instead.
mvn exec:java -Dexec.mainClass="sample.persistence.res.MainApp" -Dexec.args="cassandra"
So I am running
mvn exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”
for my Java project. It runs in Eclipse but with the command above, gives me the following errors:

I am using OS X El Capitan on a 64-bit MacBook Air mid-2012. What am I doing incorrectly?
The error is that you are giving the argument incorrectly. Your command should be:
mvn clean compile exec:java -Dexec.mainClass=com.utm.csc.HTMLParser -Dexec.args=http://www.simplehtmlguide.com
Notice the lack of quotes. This can be hinted from the error message:
java.lang.ClassNotFoundException: ”com.utm.csc.HTMLParser”
means that somehow, Java searched for a class called ”com.utm.csc.HTMLParser” but it didn't find any, simply because it is actually named com.utm.csc.HTMLParser, without the quotes.
Don't forget to compile first. exec:java doesn't do it by default.
mvn clean compile exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”
I have a big issue with my Jenkins on Mac OS. So I installed Jenkins, made a simple class and converted to Maven, created a new job on Jenkins and specify the pom.xml location ( which Jenkins sees it ok ) but when I try to build my class I always get an error as Jenkins cannot write mojo status or something.This is my console output

Regarding this error message:

I think it's more a permission problem.
Jenkins is running with a dedicated jenkins user.
Did you check this user has a R/W access in your working directory?
I tried running first of the WordCount examples and it works in Eclipse (I have Windows 7 OS), but not in shell, using the command:
mvn compile exec:java -Dexec.mainClass=com.google.cloud.dataflow.examples.MinimalWordCount
I have installed Maven and configured JAVA_HOME and Path variables and so on, however, I'm not sure what I must have missed. This is the output:

I am in the dark about how to proceed and would very much appreciate ideas of where to look next and other things to try.
Thanks!
You may have run into an issue with the documentation.
The command line you are using should work if you have cloned GoogleCloudPlatform/DataflowJavaSDK-examples. The mention of the particular repo to clone is way back in "getting started", not at all obvious if you head straight to WordCount Example Pipeline.
But if you generated the project from the Cloud Dataflow Plugin for Eclipse (or via a Maven archetype) then the examples are placed into your Java package. So instead of com.google.cloud.dataflow.examples.MinimalWordCount you will use the name my.java.project.MinimalWordCount, where my.java.project is whatever package name you chose when you created the project.
Or if you have cloned the SDK itself from GoogleCloudPlatform/DataflowJavaSDK then you will need to add -pl examples to your command line. This is because the SDK's repository is factored into maven modules; this flag instructs maven to run in the context of the examples module.
If you have a multi-module maven project (DataflowJavaSDK, not DataflowJavaSDK-examples), you can do mvn compile in the top directory, then cd into examples and then issue the mvn exec:java -Dexec.mainClass=... command there.
I installed Maven 3.1.1 for the first time. In the "Maven in 5 Minutes" getting-started guide
http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
it says to verify the installation with
mvn --version
I got the expected response:
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 11:22:22-0400)

OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"
In the next step, under "Creating a project" it says to create a new directory, open a command prompt in that directory, and execute
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
I created a directory called xjmaven, ran the command in it, and it's not working. This is the response:

I deleted pom.xml (it's the only file in the directory...the stuff it downloaded is not there), and started over again. Everything happens (badly) as I write above.
I remember trying Maven a few years ago, and could also not get past the getting-started stage.
If anyone has some advice on how to get past this, it would be appreciated. Really frustrated.
Maybe you are using Windows PowerShell?
If so, you'll need to put quotes around the parameter definitions:
mvn archetype:generate "-DarchetypeGroupId=org.apache.maven.archetypes" "-DgroupId=com.mycompany.app" "-DartifactId=my-app"
You have some syntactical errors while executing the generate goal. Moreover, you need not create the pom.xml or any dir sturcture. You will notice that the generate goal creates a directory with the same name given as the artifactId.
e.g. you are missing the convention like -DgroupId should be com.company.app (not a big issue though), having space in -Darchetype ArtifactId, etc.
I just tried below and it worked :
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
I was having a similar issue on powershell. I switched to command prompt and executed the same command and it works fine. Command that works on command prompt: mvn archetype:generate -DgroupId=com.myapp-DartifactId=hellomaven -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
The one that runs on powershell:
mvn archetype:generate "-DarchetypeGroupId=org.apache.maven.archetypes" "-DgroupId=com.myapp" "-DartifactId=my-app"
