How to run a maven project on mac - java

I am trying to run a simple maven project from the mac terminal.
Here is my pom.xml
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>HelloWorld</artifactId>
<version>1.0</version>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<build>
<plugins>
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<!-- here we specify that we want to use the main method within the Controller class -->
<mainClass>com.helloworld.Countries</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<!-- https://mvnrepository.com/artifact/com.googlecode.json-simple/json-simple -->
<dependency>
<groupId>com.googlecode.json-simple</groupId>
<artifactId>json-simple</artifactId>
<version>1.1.1</version>
</dependency>
</dependencies>
</project>
I did maven package.
and when I try to run:
java -jar target/HelloWorld-1.0.jar
… I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/simple/JSONValue
Is the java.lang.NoClassDefFoundError only on macOS? I did the same project on Windows and it works fine.
Is there anyway that we can make this independent of OS?

Solution was to use Maven-shade-plugin. Here is my final POM.

How to configure pom files and TeamCity to build dependent modules in maven java project?

I have project which consists from two modules. One of them considered to be main. So the second depends on first. Also I should generate javadoc jar files for modules. The output should be four .jar files: 2 module jar files and two javadoc jar files.
Locally, to generate both jar files I should repeat these step several times (I don't know why):
Build first one and install to local maven repository.
Then I can build second one.
Without installation of first modules I can't achieve packaging phase, because when I test second module it cannot find first module jar file.
Could I do all of these steps by one build process?

You just call mvn clean install on the parent project. It will build both modules in the right order.
I found solution. The error was received because mainmod module was accessible for secondmod module only for test scope <scope>test</scope>. Then I added new dependency with same artifactId, groupId and version, but assigned compile scope. Of course, it shows me warning about repeatition. However, it solves the problem.
Thanks for all!

AspectJ module dependency with Maven - How get working the Inter-type declarations methods of a dependency module

This is my situation:
I have a maven project my-project-aj-dependency composed by two jar modules:
my-project-aj-dependencyJarWithAJ (where I have an Inter-type declaration, see the ahah() method below inside the aspect AppWithAj_Ahah.aj)
my-project-aj-dependencyJarWithoutAJ
My problem is that I would like to use some declared method defined in the aspect of the first module inside the second module, but probably I missed something.
My poms configuration is the following:

Where AppWithAj.java is:
package org.my.project.aj.dependencyJarWithAJ;
public class AppWithAj {
public static void main( String[] args ){
System.out.println( "Hello World!" );
}
}
and AppWithAj_Ahah.aj is:
package org.my.project.aj.dependencyJarWithAJ;
public aspect AppWithAj_Ahah {
public String AppWithAj.ahah(){
return "Ahahahah!";
}
}
and finally App.java is:
package org.my.project.aj.dependencyJarWithoutAJ;
import org.my.project.aj.dependencyJarWithAJ.AppWithAj;
public class App {
public static void main( String[] args ) {
System.out.println( "Hello World! " + new AppWithAj().ahah());
}
}
Your solution is way too complicated:
The AspectJ (AJ) module needs the AJ Maven plugin and a dependency on aspectjrt. So far, so good.
But the declared aspect only affects a class within its own module, extending it via ITD. So there is no need to use the AJ compiler on the pure Java module which only calls a method from the AJ module. It is irrelevant that the called method was created by ITD, to the other module it looks just like normal Java.
Consequently, all the non-AJ module needs is a normal dependency on the AJ module because it uses one of its classes. The AJ runtime dependency is transitive and should be used automatically.

Then you should see something like this on the console:
(...)
[INFO] --- exec-maven-plugin:1.4.0:java (default-cli) # my-project-aj-dependencyJarWithoutAJ ---
Hello World! Ahahahah!
Remove Exec Maven from both the root and the plain Java POMs in order to get even shorter POMs.
I got it working with this pom configuration:

Here I show it working: AspectJ module dependency with Maven
Edit:
It seems that if the nonAj project doesn't have a AspectJ nature it warns you near the .aj defined methods (although it works fine if you simply launch it, for eclipse it is not an error, by the way this not allow you to use the autocomplete ad fills the code with wanings...). This is the snapshot:

Can't load imported class with .jar

I currently have a java-based maven project which when run, spins up jetty server and load a web app to the localhost:4567. I want to deploy this app to a server on a CentOS virtual machine but I'm not sure where to start. CentOS currently has an Apache server running, an has maven, DB, and other dependencies are installed.
I packaged the project as a .jar but I'm currently unable to run the .jar file. I get an Exception "java.lang.NoClassDefFoundError: spark/Route" when I run the jar file via command prompt or IDE.
pom.xml looks like this:

As far as I know I shouldn't have to put Spark Java into my class-path. Any one know whats going on here?
You should use the maven-assembly-plugin to build a single executable jar with dependencies included, also known as fat jar.
Instead of the maven-jar-plugin, try using the following in your pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<executions>
<execution>

In the current .pom you are building an ear and you are giving the same ear as a warModule.
You should give a .war artefact for webmodule in the ear-plugin

EAR is packing two copies of WAR and JAR projects

My Maven EAR project packs my EAR with two copies of each of my libraries. One copy is always appended with the version (In my case 1.0-SNAPSHOT). Is there something screwed up in my POMs?
I keep getting these type of errors when i try and deploy to server:
Servlet [blah...] and Servlet [blah..] have the same url pattern: [/RegistrationService_V10].
My EAR project POM looks like this :
<?xml version="1.0" encoding="UTF-8"?>

In the maven-ear-plugin, you have to specify your ejbmodule and webmodule
<plugin>
<artifactId>maven-ear-plugin</artifactId>
<version>2.8</version>
<configuration>
<modules>
<ejbModule>
<groupId>com.huwag</groupId>
<artifactId>AlmexOffice-ejb</artifactId>
</ejbModule>
<webModule>
<groupId>com.huwag</groupId>
<artifactId>AlmexOffice-web</artifactId>
<contextRoot>/custom-context-root</contextRoot>
</webModule>
</modules>
</configuration>
</plugin>
Could you give us the feedback if it works better?
