Lifecycle M2E connector for maven-protoc-plugin

This is a m2e connector to be able to build Google Protobuf Maven builds inside eclipse.

Build

To build the plugin:

mvn package

This will both create the plugin jar and the eclipse feature.

It is necessary to use Maven 3, as Maven 2 can't build connectors.

Installation

In Eclipse Indigo:

1. open the Install New Software window from the Help menu.
2. Then click on the Add button
3. select the Archive button and point it to the: com.daysofwonder.tools.m2e-protoc-connector.feature/target/com.daysofwonder.tools.m2e-protoc-connector.feature-1.0.0.20111130-1035-site.zip file.
4. Accept the license terms and restart eclipse.

Usage

Once installed, and if your project has already been imported, you must use M2E "Update Project Configuration" to instruct eclipse and m2e to use the new connector.

You project POM should use the maven-protoc-plugin like this:

	<plugin>
		<groupId>com.google.protobuf.tools</groupId>
		<artifactId>maven-protoc-plugin</artifactId>
		<executions>
			<execution>
				<id>generate proto sources</id>
				<goals>
					<goal>compile</goal>
				</goals>
				<phase>generate-sources</phase>
				<configuration>
					<protoSourceRoot>${basedir}/src/main/proto/</protoSourceRoot>
					<includes>
						<param>**/*.proto</param>
					</includes>
				</configuration>
			</execution>
		</executions>
	</plugin>
