NoClassDefFoundError when running avro-maven-plugin:protocol goal
-----------------------------------------------------------------
Key: AVRO-868
URL: https://issues.apache.org/jira/browse/AVRO-868
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.5.2
Environment: Apache Maven 3.0.3, Java 1.6.0_26, Avro 1.5.2-rc1
(experienced on multiple OSes so don't think that's important)
Reporter: Alex Miller
Priority: Blocker
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:
Caused by: org.apache.maven.plugin.PluginContainerException: A
required class was missing while executing

It appears to me that there is a missing dependency on the
FileSetManager class (which is in the
org.apache.maven.shared:file-management artifact).
My plugin execution is pretty straightforward, just generating sources
from the avpr:
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro-version}</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>protocol</goal>
</goals>
</execution>
</executions>
</plugin>
You can find the project in question in the sherpa-protocol sub-module at
https://github.com/revelytix/spark. To reproduce:
1) git clone git://github.com/revelytix/spark.git
2) cd spark/sherpa-protocol
3) In pom.xml, change:
a) <avro-version>1.5.1</avro-version> to 1.5.2
b) Add repositories section:
<repositories>
<repository>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
<id>avro-rc</id>
<name>Avro RC</name>
<url>https://repository.apache.org/content/repositories/orgapacheavro-010</url>
</repository>
</repositories>
4) mvn -X -e compile
