example of using a custom protoc plugin with gradle

[Jorg Heymans]

Hi,

We have created a java plugin to customize the sources protoc generates. It was fairly straightforward to configure this in a maven build but now we have the requirement to add it in a gradle proto project as well. The documentation is a bit sparse (at least for a gradle newbie) on how to do this https://github.com/google/protobuf-gradle-plugin#customize-code-generation-tasks , it seems to assume a good working knowledge of Gradle. So given that we have a jar containing our plugin Main class, how would i set it up in a gradle build ? In maven it looks like this:

                    <protocPlugins>

                        <protocPlugin>

                            <id>CustomProtoPlugin</id>

                            <groupId>a.b.c</groupId>

                            <artifactId>my-plugin</artifactId>

                            <version>1.0</version>

                            <mainClass>CustomPlugin</mainClass>

                            <jvmArgs>

                                <jvmArg>-DprojectProtoSourceDirectory=${project.basedir}/src/main/proto</jvmArg>

                            </jvmArgs>

                        </protocPlugin>

                    </protocPlugins>

Any projects out there that have this working ?

Thanks,

Jorg
