我正在尝试将一个 Protocol Buffer 消息导入到另一个 Protocol Buffer 消息中,但是无法识别导入。只要我不尝试将一个protobuf导入另一个protobuf,就会生成protobuf代码(在Java中),该代码将按预期编译并运行。
我正在使用:
我的gradle构建文件如下所示:
plugins {
id 'java'
id 'com.google.protobuf' version "0.8.8"
}
group 'tech.tablesaw'
version '1.0-SNAPSHOT'
sourceCompatibility = 9.0
def grpcVersion = '1.30.1' // CURRENT_GRPC_VERSION
def protobufVersion = '3.12.0'
def protocVersion = protobufVersion
repositories {
mavenCentral()
}
test {
useJUnitPlatform()
}
dependencies {
implementation "io.grpc:grpc-protobuf:${grpcVersion}"
implementation "io.grpc:grpc-stub:${grpcVersion}"
compileOnly "org.apache.tomcat:annotations-api:6.0.53"
// advanced - need this for JsonFormat
implementation "com.google.protobuf:protobuf-java-util:${protobufVersion}"
runtimeOnly "io.grpc:grpc-netty-shaded:${grpcVersion}"
testImplementation "io.grpc:grpc-testing:${grpcVersion}"
compile group: 'tech.tablesaw', name: 'tablesaw-core', version: '0.38.1'
testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version: '5.6.2'
testImplementation "org.mockito:mockito-core:2.28.2"
}
protobuf {
protoc { artifact = "com.google.protobuf:protoc:${protocVersion}" }
plugins {
grpc { artifact = "io.grpc:protoc-gen-grpc-java:${grpcVersion}" }
}
generateProtoTasks {
all()*.plugins { grpc {} }
}
}
// Inform IDEs like IntelliJ IDEA, Eclipse or NetBeans about the generated code.
sourceSets {
main {
java {
srcDirs 'build/generated/source/proto/main/grpc'
srcDirs 'build/generated/source/proto/main/java'
}
}
}
task TablesawServer(type: CreateStartScripts) {
mainClassName = 'tech.tablesaw.service.TableServiceServer'
applicationName = 'tablesaw-table-server'
outputDir = new File(project.buildDir, 'tmp')
}
task TablesawClient(type: CreateStartScripts) {
mainClassName = 'tech.tablesaw.service.TableServiceClient'
applicationName = 'tablesaw-table-client'
outputDir = new File(project.buildDir, 'tmp')
}
我的gradle信息看起来像这样:------------------------------------------------------------
Gradle 5.1.1

这是一个protobuf示例。 column_type.proto的导入失败。syntax = "proto3";
package tech.tablesaw.service.common;
import "tech/tablesaw/service/common/column_type.proto";
option java_multiple_files = true;
option java_package = "tech.tablesaw.service.common";
option java_outer_classname = "ColumnMetaProto";
option objc_class_prefix = "TSW";
// Proto file describing column metadata message.
// A column metadata object
message ColumnMetadata {
string name = 1;
int32 size = 2;
ColumnTypeEnum.ColumnType column_type = 3;
}
这是我要导入的文件:syntax = "proto3";
package tech.tablesaw.service.common;
option java_multiple_files = true;
option java_package = "tech.tablesaw.service.common";
option java_outer_classname = "ColumnTypeEnum";
option objc_class_prefix = "TSW";
enum ColumnType {
SHORT = 0;
INTEGER = 1;
LONG = 2;
FLOAT = 3;
BOOLEAN = 4;
STRING = 5;
DOUBLE = 6;
LOCAL_DATE = 7;
LOCAL_TIME = 8;
LOCAL_DATE_TIME = 9;
INSTANT = 10;
TEXT = 11;
SKIP = 12;
}
最后,这是protobuf在文件系统中的位置。src > main > java
> proto > tech > tablesaw > service > common > column_metadata.proto
> column_type.proto
最佳答案
看一看readme,它描述了如何添加其他路径。
默认情况下,intellij-protobuf-editor
使用项目配置的源根作为protobuf导入路径。如果这不正确,则可以在Settings > Languages & Frameworks > Protocol Buffers
中覆盖这些路径。取消选中“自动配置”,然后添加所需的任何路径。对于您的情况,您将添加.../src/main/java/proto
(其中...
表示项目的基本路径是什么)。
