class not found exception when running protostuff-compiler

[sbisht]

Hi protostuff team / users 

I am trying to run protostuff-compiler but always getting classNotFoundException.  io/protostuff/parser/DefaultProtoLoader is present protostuff-parser jar. 

sbisht@MacBook-Pro:~/repos/protostuff/protostuff-compiler/target$ java -cp ../../protostuff-parser/target/protostuff-parser-1.3.7-SNAPSHOT.jar -jar protostuff-compiler-1.3.7-SNAPSHOT.jar

Hi,

I afraid you cannot run protostuff compiler this way: it has many other dependencies (in addition to parser module).

Can you use maven for code generation? We have an instruction here: http://www.protostuff.io/documentation/maven-plugin/

Thanks for the response. 

I have a gradle project and would like to call protostuff compiler during the build time. Is there a gradle equivalent of maven plugin?

Hi @sbisht,

Just released new version - 1.3.7 that includes compiler jar with all dependencies:

https://repo1.maven.org/maven2/io/protostuff/protostuff-compiler/1.3.7/protostuff-compiler-1.3.7-jar-with-dependencies.jar

You can run it using "java -jar" command.

About gradle - you can try this project: https://github.com/ramonwirsch/protostuff-gradle-plugin
