I am new to gRPC , this is my simple .proto file
syntax = "proto3";
option java_package = "destiny.identity.services.grpc";
service EchoService {
rpc echo (EchoRequest) returns (EchoReply) {}
}
message EchoRequest {
string name=1;
}
message EchoReply {
string message = 1;
}
when compiles , the generated EchoServiceOuterClass.java has a lot of
incompatibilities :
Error:(83, 13) java: incompatible types: java.io.IOException cannot be
converted to java.lang.String
Error:(152, 18) java: memoizedSize has private access in
com.google.protobuf.AbstractMessage
Error:(159, 7) java: memoizedSize has private access in
com.google.protobuf.AbstractMessage
Error:(394, 18) java: cannot find symbol
symbol: method unwrapIOException()
location: variable e of type
com.google.protobuf.InvalidProtocolBufferException
Error:(586, 13) java: incompatible types: java.io.IOException cannot be
converted to java.lang.String
Error:(655, 18) java: memoizedSize has private access in
com.google.protobuf.AbstractMessage
Error:(662, 7) java: memoizedSize has private access in
com.google.protobuf.AbstractMessage
Error:(897, 18) java: cannot find symbol
symbol: method unwrapIOException()
location: variable e of type
com.google.protobuf.InvalidProtocolBufferException
What may be wrong ?
This is my pom.xml
<plugin>
<groupId>org.xolstice.maven.plugins</groupId>
<artifactId>protobuf-maven-plugin</artifactId>
<version>0.5.0</version>
<configuration>
<!--
The version of protoc must match protobuf-java. If you don't depend on
protobuf-java directly, you will be transitively depending on the
protobuf-java version that grpc depends on.
-->
<protocArtifact>com.google.protobuf:protoc:3.0.0:exe:${os.detected.classifier}</protocArtifact>
<pluginId>grpc-java</pluginId>
<pluginArtifact>io.grpc:protoc-gen-grpc-java:1.0.0:exe:${os.detected.classifier}</pluginArtifact>
</configuration>
<executions>

And the io.grpc's grpc-netty , grpc-protobuf , grpc-stub are all version of
1.0.0
