RE: Compiling Avro Schemas

[Emir Munoz]

Hi Benjamin,

 

For me seems that you didn't build the project using maven (i.e., mvn clean
install). Hence, you probably have an empty gora-tutorial/lib/ folder.

If not, I would recommend you to add the bin/ folder of gora to the PATH.

-bash-4.1$ export PATH=$PATH:/home/gora-0.3/bin 

 

And then execute the compiler inside gora-tutorial folder.

-bash-4.1$ gora goracompiler src/main/avro/pageview.json src/main/java/

 

Cheers,

Emir

Hi

I followed the tutorial given in
http://gora.apache.org/current/tutorial.html

When reaching the section Compiling Avro schemas, the command 



 
$ bin/gora goracompiler

 

returns me:

-bash-4.1$ bin/gora goracompiler gora-tutorial/src/main/avro/pageview.json
gora-tutorial/src/main/java/

How can I fix that, please?
