Maven plugin to create proto files

[rajesh]

Hi,
I was searching if there are any existing plugins which will ,
create proto files from the message files given the location and
stumbled across this .

http://groups.google.com/group/protobuf/browse_thread/thread/e3982ec04d23a0e3

What is the outcome of this discussion, is the plugin ready to be
used??? if so where is t and how do I use it. Right now Iam using some
thing like thsi in my pom file:

----- snip---
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.3</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<configuration>
<tasks>
<mkdir dir="target/generated-sources"/>
<exec executable="protoc">
<arg value="--java_out=target/
generated-sources"/>
<arg value="src/main/protobuf/
test.proto"/>
</exec>
</tasks>
<sourceRoot>target/generated-sources</
sourceRoot>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>

However I get copilation errors when I run mvn package.

Rajesh,

It looks like your issue is that you haven't set the appropriate
source version in your maven build. It defaults to a source version
for Java 1.3, but protoc creates 1.5 source. See
http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html
