I need to parse a json file in my maven project.
For that I started with a simple import in my java file (App.java)
package com.mycompany.app;
import com.fasterxml.jackson.*;// <-------- HERE
public class App
{
public static void main( String[] args )
{
}
}
Then, I tried to compile the project by using mvn package but I got an error:

Here is how I built my maven project:
I created my maven project:
mvn -B archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
I modified the file App.java (created by the previous command) to match with my file.
I modified pom.xml in order to add the dependency:
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.13.2</version>
</dependency>
Do you know how to solve this error?
I've already recently answered a similar question: the problem is that com.fasterxml.jackson is not a package, there is a folder com/fasterxml/jackson (see the source), but not a package. In Java, package is a namespace that contains at least one class. Asterix import imports non-recursively all the classes in the package. So, if you need, let's say, to use classes JsonParser.java and JacksonException.java from the package com.fasterxml.jackson.core, you may add an asterix import like that: com.fasterxml.jackson.core.*

I am trying to execute the maven project from java main
Please refer the code below.
public static void main(String args[]) throws MavenInvocationException
{
InvocationRequest request = new DefaultInvocationRequest();
request.setPomFile( new File( "C:\\Users\\DPKA764\\git\\be.axa.testautomation.phoenixiard\\pom.xml" ) );
request.setGoals( Arrays.asList( "clean", "install" ) );
Invoker invoker = new DefaultInvoker();
invoker.setMavenHome(new File("C:\\J\\apache-maven-3.5.3"));
System.out.println(""+invoker.getMavenHome());
invoker.execute( request );
System.out.println("suites are completed");
}
and when i execute the code as 'Java Application' it is throwing the following error.
[WARN] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance.

I'm trying to do this tutorial from Java EE 8 tutorial.
I'm following the instructions on how to install tutorial archetypes, which I've downloaded from this repository.
Error message printed in the bottom.
Is this related to the fact that the repository is archived, and the tutorials are outdated, or am I doing something wrong?

I could see that in mvn install command -DgroupId is not correct, instead of giving "-DgroupId=com.oracle.jdbc", you have given just "-DgroupId=com.oracle"
Maven tells you it is installing the jar to
C:\Users\l-john\.m2\repository\com\oracle\ojdbc7\12.1.0.1\ojdbc7-12.1.0.1.jar
But you are looking at

I don´t know what else I could try. I opened all the topics related to the problem.
Any other suggestion?
I had exact same problem - local maven build works and Jenkins fails with the same error as yours.
Once Jenkins job is started, it will import source code to /your-jenkins/workspace/your-job-name folder and then start building. In your DSL, you have to mention the path to your pom in the workspace.
Take a look at the Jenkins workspace view to see where your pom is located once the source code is downloaded. This will aid in resolving the problem.
in the -f option you have provided. the maven is unable to identify the pom to read
-f /Users/amhg/Documents/dev/intellik2/junitexample test
try giving in the complete name of the pom including .xml
-f /Users/amhg/Documents/dev/intellik2/junitexample nameofpom.xml
Please check what you have in your Jenkins Build -> Goals and in your Build -> POM.
You probably switched those two.
I am in the beginning phase of Maven. I created a project and was trying to use the command. what is missing at my end? I am trying to compile and run a TestSuite File:
mvn clean package

Maven works by creating a local repository in your desktop or the machine you have installed maven and running this goal.
In the process of maven running the goal, it first tries to get all the dependent jar files from Central repository as you have listed in your comments M1 or M2 and then stores them under C:/Users/yourname/.m2/repository folder (assuming you are using a windows machine) or the corresponding user folder in other OS systems.
Then it uses the jars to run the build as required per the goals given.
Now in your case, you got to figure out a way to connect to the repositories (check your settings.xml located in the .m2 folder in your User directory) and check if you can connect to the internet central maven repositories. If not you can get the jar file and manually install them as advised in the error you have got. Once you do that I think you should get past this issue. Let me know if you still have the issues.
In my case, it was caused by me doing an offline build (i.e. mvn -o install) and me not having that jar installed in my local Maven repository yet. Doing an online build (mvn install) fixed it.
