[jira] [Commented] (AVRO-868) NoClassDefFoundError when running avro-maven-plugin:protocol goal

    [ https://issues.apache.org/jira/browse/AVRO-868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13085241#comment-13085241 ] 

Holger Hoffstätte commented on AVRO-868:
----------------------------------------

I upgraded to 1.5.2 today and have been successfully using the protocol goal without any problem. Same maven version (3.0.3), JDK 1.6.25 etc. No idea why Alex is seeing this.

> I have a project that generates Java classes from a avpr using the avro-maven-plugin's protocol goal.  When I switch from Avro 1.5.1 (everything works perfectly) to 1.5.2-rc1 (also happened with rc0), I get the following error:
