Is your feature request related to a problem? Please describe. In my proto file, I want to import protobuf include proto, such as: import "google/protobuf/descriptor.proto";

Describe the solution you'd like can config in pom.xml

Describe alternatives you've considered no

You need to include google protobuf library as a dependency. You will need it in any case if you are going to generate and compile java sources. Everything else happens automatically.

        <dependency>
            <groupId>com.google.protobuf</groupId>
            <artifactId>protobuf-java</artifactId>
            <version>3.6.1</version>
        </dependency>

@sergei-ivanov i tried the following pom.xml, but it failed.

            <groupId>org.xolstice.maven.plugins</groupId>
            <artifactId>protobuf-maven-plugin</artifactId>
            <version>0.6.1</version>
            <configuration>
                <clearOutputDirectory>false</clearOutputDirectory>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>compile</goal>
                        <goal>test-compile</goal>
                    </goals>
                </execution>
            </executions>
            <dependencies>
                <dependency>
                    <groupId>com.google.protobuf</groupId>
                    <artifactId>protobuf-java</artifactId>
                    <version>2.5.0</version>
                </dependency>
            </dependencies>
        </plugin>

As I mentioned on Gitter, version 2.5.0 of protobuf library is very old and it may not have google/protobuf/descriptor.proto file packaged. Check the contents of the JAR file. If you really need to use that old protobuf library, you may need to roll your own JAR dependency with .proto files for version 2.5.0 bundled into it.
