gradle protobuf plugin not functioning - gradle

Question

I am using the below mentioned protobuf gradle plugin in one project where its working fine but when I referenced the same plugin in a different project, 'gradle clean' is consistently giving me the error copied below:
relevant parts of build.grade (v3.4)
apply plugin: 'com.google.protobuf'
buildscript {
repositories {
mavenCentral()
mavenLocal()
jcenter()
}
dependencies {
// classpath "net.ltgt.gradle:gradle-errorprone-plugin:0.0.9"
// classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.4'
classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.0'
}
}
def grpcVersion = '1.1.2'
dependencies {
compile "io.grpc:grpc-netty:${grpcVersion}"
compile "io.grpc:grpc-protobuf:${grpcVersion}"
compile "io.grpc:grpc-stub:${grpcVersion}"
}
protobuf {
protoc {
Artifact = 'com.google.protobuf:protoc:3.2.0'
}
plugins {
grpc {
Artifact = "io.grpc:protoc-gen-grpc-java:${grpcVersion}"
}
}
generateProtoTasks {
all()*.plugins {
grpc {
// To generate deprecated interfaces and static bindService method,
// turn the enable_deprecated option to true below:
option 'enable_deprecated=false'
}
}
}
}
error when I run gradle clean
* What went wrong:
Could not compile build file '/xyz/xyz/build.gradle'.
> startup failed:
build file '/xyz/xyz/build.gradle': 102: you tried to assign a value to the class 'org.gradle.api.component.Artifact'
# line 102, column 9.
Artifact = 'com.google.protobuf:protoc:3.2.0'
^
build file '/xyz/xyz/build.gradle': 106: you tried to assign a value to the class 'org.gradle.api.component.Artifact'
# line 106, column 13.
Artifact = "io.grpc:protoc-gen-grpc-java:${grpcVersion}"
I have tried protobuf plugins 0.8.0. and 0.8.1 but both give the same error. v0.8.0 works as is in a different project. Any thoughts on how to troubleshoot this further would be appreciated.

Answer 1

It should be artifact, not Artifact. The latter is a class that you try to assign to which will not work, the former is a property you assign to.
