My problem was a internet problem while download the dependencies, so some files was breaking. I solved deleting the directory ".m2" and executing mvn clean install to re-install the dependencies.


You've got an end-tag dependencies but no start-tag dependencies
(missing tag should be between properties-tag and firts dependency)


Besides the <dependencies> tag missing, you have a problem on the <project> tag as well. This should do it:

This mostly happens when you changes versions of eclipse on a single system. Try clearing .m2 directory. It should resolve the issue.


Do Project->Clean, just clean up the project and the error is gone.

Maven parent - sharing bom dependencies with child artefacts

I have several Maven artefacts, who are all children of a parent which is used to centralise versions of dependencies in use.
For example, apple and pear are both children of maven-parent.
maven-parent defines version 3.12.0 of commons-lang3 and both children declare a dependency of commons-lang3, but do not need to specify the version and are consistent.
This works well, but I'd like to use the Google Cloud libraries in both apple and pear.
The documentation says this needs to be done using a bom dependencyManagement entry.
I've got this working on a per-project basis, but I can't get this centralise - both apple and pear would like different parts of Google Cloud but both should be using the same version of the libraries to do so.
This is especially important as pear depends on apple and could end up overriding it's dependency versions if not careful.
What I'd like to do is move the declaration of the version of Google's libraries-bom version of 24.0.0 into maven-parent.

take a look and see how I can fix this.
Cannot resolve commons-collections:commons-collections:2.1
Cannot resolve org.apache.commons:commons-collections4:4.4
Cannot resolve commons-digester:commons-digester:1.6
Cannot resolve xml-apis:xml-apis:1.0.b2
Cannot resolve commons-logging:commons-logging:1.0.4

The error is "Cannot resolve commons-collections:commons-collections:2.1"
It has nothing to do with "commons-validator" dependency.
The commons collection artifact has moved to a different location in maven artifactory.
Please check this out
https://mvnrepository.com/artifact/org.apache.commons/commons-collections4

try to change version of your package, but better find dependency in https://mvnrepository.com/ which you need, copy this text and try to reimport.

You are mixing junit 4 (in the test definition) and junit 5 (in your pom.xml).
If it is ok to use junit 4 for you, try with the following (edited) version of your pom.xml file; I have removed the surefire plugin configurations- the defaults work ok:

I have been following this:
http://www.openimaj.org/tutorial/processing-video.html
But for some reason the XuggleVideo classes and anything that has to do with video is not detected.
My project is divided in separate packages. I don't think that matters in maven anyway.
Is my pom.xml file setup wrong?

Use this repo <url>http://www.openimaj.org</url> instead <url>http://maven.apache.org</url>
