Protobuf extension exception

[Taylor McKinnon]

Hi,

I'm trying to install the newly released Warp10 protobuf extension. I am able to install and configure it, and am able to see it load in the logs, however the first call to PROTOC causes an exception.

warp10_1 | Exception in thread "[Warp Macro Repository (/usr/local/share/warpscript)" java.lang.NoSuchMethodError: com.google.protobuf.DescriptorProtos$FileDescriptorProto.getDependencyList()Lcom/google/protobuf/ProtocolStringList;

Hi,

If you installed the extension downloading the jar from https://warpfleet.senx.io/browse/io.warp10/warp10-ext-protobuf and adding it to the classpath, you also need to do that for the 2 dependencies.

If you used the WarpFleet CLI (https://warpfleet.senx.io/doc#cookbook, section retrieve an artifact), the dependencies should have already been pulled and this is another problem.

I am currently using a docker image derived from the official warp 10 image where I manually download the deps from maven and install them into the /opt/warp10/lib/ directory. (The Dockerfile for the image can be found here)

I have also tried using warpfleet but received the same error.

There is an issue with the current version of the WarpFleet cli which does not correctly fetch the dependencies declared in the .pom files.

We have published a version of the Protobuf extension as an uberjar, check version 1.1.0-uberjar, it should solve your issue.

WarpFleet will be fixed in an upcoming release.

Hi, the WarpFleet CLI is fixed, it manages dependencies.

To update:  npm install -g @senx/warpfleet

Best regards.
