Maven error - java.lang.NoClassDefFoundError: org/slf4j/helpers/MarkerIgnoringBase

Question

Getting up and running with Maven.

Trying to build a project I\'ve inherited. I\'ve resolved majority of the issues but am now seeing a weird error:

Answer 1

Thats an open issue in Maven https://issues.apache.org/jira/browse/MNG-5787. I was facing the exact same issue and got it fixed by upgrading Maven from 3.3.1 to 3.3.9.

Answer 2

For all AEM users, who experience the same problem after generating a maven project with the archetype: I solved the problem by updating the version of the content-package-maven-plugin to version 0.0.24:

            <plugin>
                <groupId>com.day.jcr.vault</groupId>
                <artifactId>content-package-maven-plugin</artifactId>
                <version>0.0.24</version>
                <extensions>true</extensions>
                <configuration>
                    <failOnError>true</failOnError>
                    <username>${crx.username}</username>
                    <password>${crx.password}</password>
                </configuration>
            </plugin>

Answer 5

In the end I chose the simplest solution which didn't require a work around of custom POM configuration.

Reverted to using Maven 3.2.5

Answer 6

I had the same problem, I'm using MAC-OS

this command wasnt working:

mvn -PautoInstallPackage install

then I had to go to this folder

/usr/local/apache-maven/apache-maven-3.3.3/

and then i download the 3.0 version and put those files inside ...

and is working !!!!!!!!!!!!!

so I put the folder apache-maven-3.0.5 but I changed the name to apache-maven-3.3.3, then I closed the terminal, re-opened it and put

export PATH=$PATH:/usr/local/apache-maven/apache-maven-3.3.3/bin

and voila !!!!!!!!!!! is working !!

NOW I CAN USE

mvn -PautoInstallPackage install

TO UPLOAD MY PROJECTS TO AEM CRX/DE
