Maven build fails with "package com.fasterxml.jackson does not exist"

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.*

mvn install:install-file is unable to install ojdbc7.jar at correct location

I am having difficulty in getting this ojdbc7 JAR file installed in the correct location. I tried the following from Windows 10 command prompt and got the BUILD SUCCESS message as shown below:

In my pom.xml, I do have the dependency defined as follows:
Is there anything I am doing wrong? Please let me know if I need to perform some additional testing?

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
C:\Users\john\.m2\repository\com\oracle\ojdbc7\12.1.0.1

Jenkins Non-readable POM

This error is posted in different forums even here. I have tried the different alternatives. I tried changing the POM permissions. I am using the default maven settings. JDK is 8, Maven 3.5.3.
I just want to try a very simple junit application. From the command line I have no problems running "mvn test"

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.

Any help appreciated.
I'm new to Maven. I got the below command from tutorials point

Can someone please help.

The relevant error is pointing to a connection problem:
Could not transfer artifact org.codehaus.groovy:groovy:jar:1.8.3
from/to central (http://repo.maven.apache.org/maven2): GET request
of: org/codehaus/groovy/groovy/1.8.3/groovy-1.8.3.jar from central
failed: Connection reset
The command which you posted actually runs fine on my machine. If you execute this maven command and you do not have the Groovy libraries yet, you will see that it actually downloads the following files:
https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy/1.8.3/groovy-1.8.3.pom
https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy/1.8.3/groovy-1.8.3.jar
It might be that you have only access to the internet via a proxy. In this case you will need to setup a proxy in the Maven configuration.
This blog here contains a fairly good description on how to setup a proxy for Maven, so that Maven can access the repository libraries.
Another option to tackle your problem would be to manually download this file using your browser:
https://repo.maven.apache.org/maven2/org/codehaus/groovy/groovy/1.8.3/groovy-1.8.3.jar
And then install it in your repository manually using:
mvn install:install-file -Dfile=<path-to-file> -DgroupId=org.codehaus.groovy \
-DartifactId=groovy -Dversion=1.8.3 -Dpackaging=jar
But normally you should not have to do this manual download + installation. Maven should be doing this for you.

-Dsonar.login=$SONAR_TOKEN \
-Dsonar.projectVersion=$INITIAL_VERSION
Why I am seeing this error No license for governance as I am not using any commercial sonar component (only sonar-java I suppose)?
The problem seems to be related to the fact that one of the plugins needs a commercial key, but How I can tell Travis to only install the java plugin?

Taking a look at your repository, you should not override the various parameters that the Travis Add-on is specifying for you.
More specifically, when you override SONAR_TOKEN on the Maven command line (at line 12), the consequence is that the token that you have encrypted and passed at line 11 of your .travis.yml file is completely wiped out. Because of this, your analysis is run like if you were anonymous.
So please follow the Get Started guide and simply run the following Maven command:
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent package sonar:sonar

sonar-governance plugin is commercial plugin.
