Failed to execute goal org.xolstice.maven.plugins:protobuf-maven-plugin:0.6.1:compile-custom protoc did not exit cleanly

Question

I've been struggling with the following error.

[ERROR] Failed to execute goal org.xolstice.maven.plugins:protobuf-maven-plugin:0.6.1:compile-custom (compile) on project grpc: protoc did not exit cleanly. Review output for more information. -> [Help 1]

I have a parent pom where I have defined plugin under pluginManagement tag. In child pom I am using the plugin defined in parent pom. Here is how my pom file looks like.

Parent pom:

<pluginManagement>
             <plugin>
                <groupId>org.xolstice.maven.plugins</groupId>
                <artifactId>protobuf-maven-plugin</artifactId>
                <version>0.6.1</version>
             </plugin>
</pluginManagement>

Child pom:

    </plugins>
         <plugin>
            <groupId>org.xolstice.maven.plugins</groupId>
