Ryan Skraba commented on AVRO-3179:
-----------------------------------
Hello! I just want to confirm that my generated class of Value had *{{public
void setNomandat(java.math.BigDecimal value)}}*
I'm not using Kafka or postgres in my example.
Are you setting the {*}enableDecimalLogicalType{*}? My maven plugin is
configured like this:
{code:java}
<build>
<plugins>
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>1.10.2</version>
<executions>
<execution>
<goals>
<goal>schema</goal>
<goal>protocol</goal>
<goal>idl-protocol</goal>
</goals>
<phase>generate-sources</phase>
<configuration>
<enableDecimalLogicalType>true</enableDecimalLogicalType>
<fieldVisibility>public</fieldVisibility>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build> {code}
And I'm using *{{mvn generate-sources}}* to generate the specific records.
You can also use avro-tools:
{code:java}
mvn dependency:get -Dartifact=org.apache.avro:avro-tools:1.10.2
java -jar
~/.m2/repository/org/apache/avro/avro-tools/1.10.2/avro-tools-1.10.2.jar
compile -bigDecimal schema table.avsc .
grep -r setNomandat .
# you should see public void setNomandat(java.math.BigDecimal value){code}
> ClassCastException: java.math.BigDecimal cannot be cast to java.nio.ByteBuffer

> Hello,
> I think we have the same problem as AVRO-2212.
> I have classCassException with a bigDecimal.
>
> Context :
> I am doing an ETL with postgres >> KafkaConnect >> KafkaStream
> I get schemas with mvn schema-registry:download
> I generate pojo with : mvn clean avro:schema
> Then I launch my app to stream a table source to a table target
> see schema here : [^table.avsc]
>
> I have fixed passing on the 1.10.1 version and it works. But When i take
> 1.10.2 I have the bug :
> Caused by: java.lang.ClassCastException: java.math.BigDecimal cannot be cast
> to java.nio.ByteBufferCaused by: java.lang.ClassCastException:
