I've created a simple project in Java Maven. I can run this project by:
1:
java -cp target/MavenTestApp-1.0-SNAPSHOT.jar org.koushik.javabrains.App
But I would like to run it by:
2:
java -jar target/MavenTestApp-1.0-SNAPSHOT.jar
To run it by second method I need to change manifest file. I am using maven so I think that in this case I need to change the pom.xml file. My pom.xml file is:
<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">
<modelVersion>4.0.0</modelVersion>
<groupId>org.koushik.javabrains</groupId>
<artifactId>MavenTestApp</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>MavenTestApp</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
I need to add something like this:
<mainClass>org.koushik.javabrains.App</mainClass>
But I not pretty sure where and how to do that? Could you also tell me if this line is good:
2:
java -jar target/MavenTestApp-1.0-SNAPSHOT.jar
Maybe at the end of this line there should be something or it is sufficient? Thanks.
Take a look at the Maven jar plugin documentation.
You will need to configure something similar in your .pom:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
...
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>org.koushik.javabrains.App</mainClass>
</manifest>
</archive>
</configuration>
...
</plugin>
</plugins>
</build>
...
</project>

I am using maven project for UI automation and I need to run some tests in multiple environment and multiple browsers.
I have created added the pom.xml file and declared the properties in it. But when i execute it through the terminal i get errors.
command i used-
mvn clean
mvn test -Denvironment=test -Dbrowser=chrome

You have error during the parson pom.xml file I checked it into my Idea and corrected. You didn't have </project> tag and <dependencies> </dependencies> were redundant. Also there should be answer

After this the file builds correctly.

I have seen u r POM couple of ties and have seen my local pom how I have defined my dependencies and POM
I found 2 things
You have defined the properties already in which u can directly add the value
(Here in your case it is environment and Browser)
else define alone as follows in properties
${environment}
I haven't seen end for the Project in the POM.
Try adding that and that should work.

I am trying to test the basic structure of my GUI application that I started using WindowBuilder. I am also using Maven so that I can just download the dependencies from their repository.
I don't have any errors when I do a "Maven Clean" or a "Maven Install", but when I try to do "Run As--->Java Application", I get the following error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-win32-3044 in java.library.path
swt-win32-3044 was what I found in the Maven Repository to satisfy the requirements for the WindowBuilder. I don't have any errors in my POM file, but here is what I have...
<project xmlns="http://maven.apache.org/POM/4.0.0"

Any help would be greatly appreciated. Thanks.
So I changed the POM around a little bit. I tried a different Maven dependency for WindowBuilder and changed my syntax for defining the maven-surefire-plugin.

It now launches the Java application window as expected.
I am using maven in my project & I've put database.properties file under
maven resources folder.
I am accessing it in spring application context
<context:property-placeholder location="classpath:database.properties" />
But I don't understand why I am getting this file not found error on server start.
Could not load properties; nested exception is
java.io.FileNotFoundException: class path resource
[database.properties] cannot be opened because it does not exist
To my knowledge whatever resource is put under resources folder it is added to the classpath automatically by maven.

NOTE: Seems like there is some problem with the M2E plugin of eclipse luna. Executed the same code in Juno & it worked fine.
That's not enough to build a deployable war file with maven. You need at least the war plugin. There's a thorough tutorial here:
http://crunchify.com/how-to-create-a-war-file-from-eclipse-using-maven-plugin-apache-maven-war-plugin-usage/
Your pom will look something like below, and you'll need to run mvn clean install against that.
Also I see you have a spring app, where are the spring dependencies in the pom file?

Hello all I'm pretty new to using maven to build Java project so I'm sure the solution to my problem will be quite easy. I have installed the Eclipse Maven plugin and created a maven project. I now wish to package this project and distribute it as a runnable jar file. However when I run
mvn package
and then try to run the jar file I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: main/Formatter
The pom for this particular file looks like so:
<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">

Any help would be greatly appreciated.
You need to specify the main class in the jar plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>main.Formatter</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
If you want to distribute a single jar you need to use a single-jarifier (fatjar, jarjar, onejar, etc.)
