Incompatibility with grpc-java 1.33.0

[djaneluz]

My application uses grpc.version = 1.33.0 and the server works just fine. But when I add this client lib and try to use it, I get the error:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    net.devh.boot.grpc.client.channelfactory.ShadedNettyChannelFactory.newChannelBuilder(ShadedNettyChannelFactory.java:73)

The following method did not exist:

    'io.grpc.internal.AbstractManagedChannelImplBuilder io.grpc.netty.shaded.io.grpc.netty.NettyChannelBuilder.defaultLoadBalancingPolicy(java.lang.String)'

The method's class, io.grpc.netty.shaded.io.grpc.netty.NettyChannelBuilder, is available from the following locations:

    jar:file:/C:/Users/d_luz/.m2/repository/io/grpc/grpc-netty-shaded/1.33.0/grpc-netty-shaded-1.33.0.jar!/io/grpc/netty/shaded/io/grpc/netty/NettyChannelBuilder.class

The class hierarchy was loaded from the following locations:

    io.grpc.netty.shaded.io.grpc.netty.NettyChannelBuilder: file:/C:/Users/d_luz/.m2/repository/io/grpc/grpc-netty-shaded/1.33.0/grpc-netty-shaded-1.33.0.jar
    io.grpc.ForwardingChannelBuilder: file:/C:/Users/d_luz/.m2/repository/io/grpc/grpc-api/1.33.0/grpc-api-1.33.0.jar
    io.grpc.ManagedChannelBuilder: file:/C:/Users/d_luz/.m2/repository/io/grpc/grpc-api/1.33.0/grpc-api-1.33.0.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of io.grpc.netty.shaded.io.grpc.netty.NettyChannelBuilder


Process finished with exit code 1

I'm using the last version

    <dependency>
        <groupId>net.devh</groupId>
        <artifactId>grpc-client-spring-boot-starter</artifactId>
        <version>2.10.1.RELEASE</version>
    </dependency>

Which I noticed use an older version of io.grpc. I'm not sure if this is causing the problem.

Any ideas on how to fix this?

This looks like an incompatibility due to the grpc-java update.
Your options:

1. Downgrade grpc-java
2. Wait for the next release of this library
3. Temporarily overwrite/recompile the offending class (ShadedNettyChannelFactory) by copying it to your code.

Waiting for grpc-java v1.33.1 release
