Error while generating using proto definition

I'm using a mac m1 with open jdk 11 and trying to generate using proto definition.

openjdk version "11.0.18" 2023-01-17 LTS
OpenJDK Runtime Environment Zulu11.62+17-CA (build 11.0.18+10-LTS)
OpenJDK 64-Bit Server VM Zulu11.62+17-CA (build 11.0.18+10-LTS, mixed mode)

I have the following defined in the parent pom.

<plugin>
    <groupId>org.xolstice.maven.plugins</groupId>
    <artifactId>protobuf-maven-plugin</artifactId>
    <version>${protobuf-maven-plugin.version}</version>
    <configuration>
        <protocArtifact>
            com.google.protobuf:protoc:3.3.0:exe:${os.detected.classifier}
        </protocArtifact>
        <pluginId>grpc-java</pluginId>
        <pluginArtifact>
            io.grpc:protoc-gen-grpc-java:1.4.0:exe:${os.detected.classifier}
        </pluginArtifact>
        <clearOutputDirectory>false</clearOutputDirectory>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>compile-custom</goal>
                <goal>compile</goal>
            </goals>
        </execution>
    </executions>
</plugin>

When generating I'm getting the following error.

[ERROR] Failed to execute goal org.xolstice.maven.plugins:protobuf-maven-plugin:0.6.1:compile-custom (default) on project com.sample.resource.monitoring.service: Unable to resolve artifact: Missing:

As a work around I upgraded protoc to 3.17.3 and gen-grpc-java to 1.49.1. This fixed the issue but conflicts when I integrate with other services. For some of my fellow devs this works without any issue. So far I have not been able to find what's the issue with existing configurations.

Any idea on how to fix this?

Solution

  • It's known issue: https://github.com/grpc/grpc-java/issues/7690 but there are also suggestions what to in that case:

    1. replace ${os.detected.classifier} with osx-x86_64

    2. set maven active profile property os.detected.classifier to osx-x86_64
