Apache Avro RPC Quick Start.

avro-rpc-quickstart's Issues

When running mvn command in Windows, should use " instead of '

When I build the jar with java8 and run the mvn command in windows, I got the error:
[ERROR] Unknown lifecycle phase "pat".

mvn -v:
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: D:\apache-maven-3.3.9
Java version: 1.8.0_60, vendor: Oracle Corporation
Java home: C:\Java\jdk1.8.0_60\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 7", version: "6.1", arch: "amd64", family: "dos"

And I change the
 mvn -e exec:java -Dexec.mainClass=com.lyl.dfs.Main -Dexec.args='avro_user pat Hello_World' 

to

 mvn -e exec:java -Dexec.mainClass=com.lyl.dfs.Main -Dexec.args="avro_user pat Hello_World"

Then it works well...

avro-maven-plugin chicken-and-egg problem.

Thanks for putting this together!

I ran into an issue following the README. The avro-maven-plugin is in the same directory as pom.xml, as a result, when the maven install is run:

mvn install:install-file -Dfile=./avro-maven-plugin-1.0-SNAPSHOT.jar -DpomFile=./avro-maven-plugin-1.0-SNAPSHOT.pom

The project's pom is picked up and complains that the avro-maven-plugin can't be found (because it isn't installed yet). One solution would be to push the plugin into its own subdirectory directory sans pom.

Getting an ClassNotFound exception when using version 1.8.1 of avro

Hello I'm getting an error after downloading and executing:

mvn clean generate-sources

[ERROR] Failed to execute goal org.apache.avro:avro-maven-plugin:1.8.1:protocol (schemas) on project avro-rpc-quickstart: Execution schemas of goal org.apache.avro:avro-maven-plugin:1.8.1:protocol failed: A required class was missing while executing org.apache.avro:avro-maven-plugin:1.8.1:protocol: org/codehaus/jackson/node/TextNode [ERROR] ----------------------------------------------------- [ERROR] realm = plugin>org.apache.avro:avro-maven-plugin:1.8.1 [ERROR] strategy = org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy

I'm new to Avro and was looking for an example that works with version 1.8.1, so I found this project but also checking this code out I'm receiving the same error.
I tried first the explination on the official avro page where I received the same error while having everything configured as they mentioned.

I do see the jackson-mapper-asl-1.9.13.jar containing the missing class on my classpath (org.codehaus.jackson.node.TextNode.class) added by maven so I'm not sure why it is not working.

The only version that is working without error for me is Avro version 1.7.5. Newer versions than that are giving me the error mentioned above. Any tips or hint would be helpfull.

I'm running it under
OS: Ubuntu 16.04 LTS,
Java: JDK 1.8.0_121
IDE: Neon.2 Release (4.6.2)
maven: 3.3.9

Interoperability between Java and Ruby doesn't exist

I'm trying to build a Java server with a Ruby client and for some reason doesn't work, apparently there is a error comparing types between Java and Ruby which raise the following exception:

Any idea how to fix this?

Can convert Java project to use CharSequence but not String

Hi, great demo by the way.

I was trying to convert the Java project to use String, but can only get as far as changing Main.java to use String. I can get Mail.java and Message.java to use CharSequence, but I'm surprised that when everything is String I still get an error even though there are seemingly no more Utf8s left in the project:

Caused by: org.apache.avro.AvroRuntimeException: java.lang.ClassCastException: org.apache.avro.util.Utf8 cannot be cast to java.lang.String

    at org.apache.avro.ipc.NettyTransceiver$NettyClientAvroHandler.messageReceived(NettyTransceiver.java:613)

Any ideas on how to use String throughout?
Thanks
