Unable to compile and create .avro file from .avsc using Maven - maven

Question

I'm new to Maven and have been looking at tutorials and web for documentation on how to build a .avro from a schema file .avsc. Based on the documentation that on the apache.maven.org site. I have to add the following
<dependency>
<groupId>org.apache.avro</groupId>
<artifactId>avro</artifactId>
<version>1.7.5</version>
</dependency>
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>1.7.5</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>schema</goal>
</goals>
<configuration>
<sourceDirectory>${project.basedir}/src/main/avro/</sourceDirectory>
<outputDirectory>${project.basedir}/src/main/java/</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
I've added the same into my POM.xml file. I have 2 schema files (.avsc) and following is my directory structure with contents
ProjectDir
src
main
java
avrò
abc.avsc
resources
test
pom.xml
My POM.xml is
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Appreciate any help in this regard. thank you

Answer 1

After a lot of research I found that the problem was completely with my .avsc JSON problem. The "namespace" was totally wrong. As soon as I fixed it. The maven avro plugin created the java class from the schema.

Answer 2

First of it is not the JSON issue. Issue occurred due to addition of tag in t he pom.xml
Points to note :
defines the settings for plugins that will be inherited by child modules in your build. This tag is not required until it is parent POM.
i.e tag is used to manage plugin in child modules.
So no need to add the tag in pom.xml.
If there is any error "Plugin execution not covered by lifecycle configuration" then it is because of the older avro version try to look for latest version it will resolve the issue.

Answer 3

for anyone else that has has the issue.
Also if your configuration is being ignored then moving the configuration block under the plugin section works. It worked for me on the version 1.11.0. I found the fix in this stackoverflow.
Apache Avro maven plugin seems to be ignoring config
Also this github repo is very useful for testing out making a avro file in to java file. there is no custom configuration in it though which you can add yourself.

Also I found this command very useful for debugging f directories do not exist when it is producing the files. It tells you the exact problem.
mvn -X avro:schema
