Suddenly problems with vaadin's maven repository

Flow
1

I’m building my vaadin project with maven for years now. But today all vaadin projects fail to compile or update. I tested the behavior also with a completely new archetype project, but it failed too:

I followed the guide on https://vaadin.com/wiki/-/wiki/Main/Creating+a+Maven+project to create the architype project.

Hi Stefan,
did you try to clear your local repository?

4

Yes. I completely removed my local copy and I tested it now also on another computer. The Sonatype maven repository seems to be corrupted.

It’s reproducable:

  • create a new project mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.1.8 - build it
mvn package

I am having the same problem on our integration server which starts from a completely clean maven repo. Here is the relevant section from the log:

I updated the pom to refer to Vaadin 7.2.3 and cleared out everything and now I get the following error

Cannot find parent: org.codehaus.mojo:mojo-parent for project: com.vaadin:vaadin-maven-plugin:maven-plugin:7.2.3 for project com.vaadin:vaadin-maven-plugin:maven-plugin:7.2.3 Incidentaly this is the same error that was causing the checksum to fail because in maven couldn’t find a valid reference to mojo-parent (on oss.sonatype.org).

Hi, Same issue here…

The issue I guess is that vaadin-maven-plugin defines a parent:

org.codehaus.mojo mojo-parent 30

and the plugin repository from archetype point to :

vaadin-snapshots
http://oss.sonatype.org/content/repositories/vaadin-snapshots/

true

Then maven try to find the vaadin-maven-plugin at that pluging repository and in not found with some error page,

I think some how the pom.xml from vaadin-maven-plugin mudt be fixed…

Thanks in advance!

hello,

i was bitten by the same problem and after removing my .m2 directory i could not compile any vaadin maven project anymore.
the fix is upgrading to maven 3 (i was still using maven 2 as this is the maven that comes with ubuntu)

greetings,
frank

Ah yes, with maven 3 it works!

Thanks a lot, Frank!
