我从micronaut.lanch下载了一个简单的grpc项目，我可以构建它，直到我添加了Kotlin gRPC插件。
除了build.gradle.kts中的更改之外，除了原始的scafolded项目之外，没有其他任何东西。
我是在build.gradle.kts中编辑的。
首先，为了匹配IntelliJ Kotlin版本
plugins {
id("org.jetbrains.kotlin.jvm") version "1.4.21"
id("org.jetbrains.kotlin.kapt") version "1.4.21"
id("org.jetbrains.kotlin.plugin.allopen") version "1.4.21"其次，为kotlin grpc proto自动生成的文件添加了文件夹
sourceSets {
main {
java {
...
srcDirs ("build/generated/source/proto/main/grpckt")最后
protobuf {
protoc {
artifact = "com.google.protobuf:protoc:3.14.0"
}
plugins {
id("grpc") {
artifact = "io.grpc:protoc-gen-grpc-java:1.33.1"
}
id("grpckt")
{ artifact = "io.grpc:protoc-gen-grpc-kotlin:0.1.2" }
}
generateProtoTasks {
ofSourceSet("main").forEach {
it.plugins {
// Apply the "grpc" plugin whose spec is defined above, without options.
id("grpc")
id("grpckt")
}
}
}
}无论是从INtelliJ构建还是直接从命令行构建，结果都是
C:\_d\toLearn\kafka-proto\build\tmp\kapt3\stubs\main\com\test\KafkaProtoServiceGrpcKt.java:35: error: incompatible types: NonExistentClass cannot be converted to Annotation
@error.NonExistentClass()*已编辑
tasks {
compileKotlin {
kotlinOptions {
jvmTarget = "11"
}
dependsOn ="generateProto" //how add this ?????
}
compileTestKotlin {
kotlinOptions {
jvmTarget = "11"
}
}
}*编辑2
我试过另一个项目。我从头开始，我又被同样的问题卡住了。
这是build.gradle
plugins {
id("org.jetbrains.kotlin.jvm") version "1.4.10"
id("org.jetbrains.kotlin.kapt") version "1.4.10"
id("org.jetbrains.kotlin.plugin.allopen") version "1.4.10"
id("com.github.johnrengelman.shadow") version "6.1.0"
id("io.micronaut.application") version "1.2.0"
id("com.google.protobuf") version "0.8.13"
}
version = "0.1"
group = "com.tolearn"
repositories {
mavenCentral()
jcenter()
}
micronaut {
testRuntime("junit5")
processing {
incremental(true)
annotations("com.tolearn.*")
}
}
//https://stackoverflow.com/a/55646891/4148175

// correctErrorTypes true
//}

}
application {

}
java {

}
tasks {
compileKotlin {
kotlinOptions {
jvmTarget = "11"
}
dependsOn ':generateProto'
}
compileTestKotlin {
kotlinOptions {
jvmTarget = "11"
}
}
}
sourceSets {
main {
java {
srcDirs("build/generated/source/proto/main/grpc")
srcDirs 'build/generated/source/proto/main/grpckt'
srcDirs("build/generated/source/proto/main/java")
}
}
}
protobuf {
protoc { artifact = "com.google.protobuf:protoc:3.14.0" }
plugins {
grpc { artifact = "io.grpc:protoc-gen-grpc-java:1.33.1" }
grpckt { artifact = "io.grpc:protoc-gen-grpc-kotlin:1.0.0:jdk7@jar"}
}
generateProtoTasks {
all()*.plugins {
grpc {}
grpckt {}
}
}
}该问题在自动生成的存根上出现

多亏了https://github.com/grpc/grpc-kotlin/issues/220的帮助，我通过添加api("io.grpc:grpc-kotlin-stub:1.0.0")修复了这个问题。
所以我的build.gradle现在是：
plugins {
id("org.jetbrains.kotlin.jvm") version "1.4.10"
id("org.jetbrains.kotlin.kapt") version "1.4.10"
id("org.jetbrains.kotlin.plugin.allopen") version "1.4.10"
id("com.github.johnrengelman.shadow") version "6.1.0"
id("io.micronaut.application") version "1.2.0"
id("com.google.protobuf") version "0.8.13"
}
version = "0.1"
group = "com.tolearn"
repositories {
mavenCentral()
jcenter()
}
micronaut {
testRuntime("junit5")
processing {
incremental(true)
annotations("com.tolearn.*")
}
}
//https://stackoverflow.com/a/55646891/4148175
