Summary: How to run an Eclipse Java Maven Project outside of Eclipse
Details:
I am a Maven newbie and I have created a very simple Maven project in Eclipse.
The Package Explorer view of my project is as follows:
The source code for the two simple Java files is as follows:
package Pkg01;
public class Calculator
{
public double add(double number1, double number2)
{
return number1 + number2;
}
public static void main(String[] args) {
Calculator calculator = new Calculator();
System.out.println(calculator.add(100, 200));
}
}
and
package Pkg01;
import junit.framework.TestCase;
public class TestCalculator extends TestCase
{
public void testAdd()
{
Calculator calculator = new Calculator();
double result = calculator.add(10, 50);
assertEquals(60, result, 0);
}
}
From within Eclipse I am able to run the Java Application, the Junit Test and the Maven test, without any issues.
My question is how can I invoke the mvn command from the DOS shell so that I can:
Run the Java Application
Run the Junit Test
Run the Maven test
BTW running mvn exec:java from the parent directory of the project is not executing the Java application for me.
My pom.xml file looks like this:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Here are the reasons why I feel that my question is not a duplicate.
I created a very simple project with maven-archetype-quickstart and my environment is correct because everything {i.e. (1) Run the Java Application, (2) Run the Junit Test and (3) Run the Maven test} works for me within the Eclipse IDE environment. The other poster was having trouble executing, which I don’t.
The comments that the other poster received were mainly for fixing his environment to get it running. I don't have that issue since, as already mentioned, everything works for me within the Eclipse IDE environment.
All I am asking is what I need to do get the following things working from the command shell:
Running the Java Application
Running the Junit Test
Running the Maven test
The error message states parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin.If you look at the exec:java documentation the required parameter is mainClass
I don't see exec-maven-plugin being configured in your pom.xml so you could execute Java programs using below command
mvn exec:java -Dexec.mainClass="com.example.Main"
Make sure you have compiled you code either using mvn compile or mvn install command before running mvn exec.. command
C:\data\development\app_code\my-app>mvn exec:java -Dexec.mainClass="com.mycompany.app.App"

I do see the same details being mentioned in the link by Karthikeyan Vaithilingam
Reference:
https://www.mojohaus.org/exec-maven-plugin/usage.html
OP Addendum
You have provided the solution for:
1. Running the Java Application
3. Running the Maven test
From the IDE I can also invoke:
2. Running the Junit Test
Admittedly this is very similar to 3. Running the Maven test but the output looks different.
Is there a way to do that from outside of the IDE environment?

I was using the followig command to build the project
mvn compile exec:java clean install
and it was working. I wished it to install sources to local repository and wrote
mvn compile exec:java source:jar clean install
and now it fails with

how to fix/overcome?
Try
mvn clean source:jar compile install exec:java
Or just:
mvn clean source:jar install exec:java
So basically you need to put the "clean" before the "source:jar"
or else installation for sources will fail
TL;DR
Maven does not find <importedGroupid>:<importedArtifactid>:jar:1.0 in repository file://<homeDirectory>/.m2/repository/. The package actually is in <homeDirectory>/.m2/repository/<importedGroupid>/<importedArtifactid>/1.0/
I do not presume to understand Maven, but the two potential reasons I could imagine are:
it gets confused with : and / (i.e. UNIX style path seperator vs. whatever : means in Maven), or
if : and / are actually interpreted as the same, the path it searches for includes another subdirectory level jar that is not present in the real directory structure.
Detailed Explanation
I was trying to import a package locally in Maven (as the package is not deployed online). Various answers (e.g., this, and this) on stackoverflow recommend running mvn install on the jar containing the package like so (assuming the jar is in /usr/share/java, is version 1.0, etc. etc.):
mvn install:install-file -Dfile=/usr/share/java/<importedArtifactid>-1.0-SNAPSHOT.jar -DgroupId=<importedGroupid> -DartifactId=<importedArtifactid> -Dversion=1.0 -Dpackaging=JAR -DgeneratePom=true
and defining this in the current package's pom.xml by adding:
<repository>
<id>repository</id>
<url>file://${user.home}/.m2/repository/</url>
</repository>
The mvn install command deploys the package into <homeDirectory>/.m2/repository/. So far, this works fine:
<prompt> $ mvn install:install-file -Dfile=/usr/share/java/<importedArtifactid>-1.0-SNAPSHOT.jar -DgroupId=<importedGroupid> -DartifactId=<importedArtifactid> -Dversion=1.0 -Dpackaging=JAR -DgeneratePom=true

I had the same issues and I found out that the problem was that some of tests tried to create a System link and it was not possible because I didn't start my IDE (IntellijIdea) as administrator in Windows.
I started Intellij as administrator and that solved the problem.
Skipping test is not a good practice when developing.
mvn -Dmaven.test.skip=true -DskipTests=true clean install
use this command

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 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)

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"
