与Maven依赖项有关的问题:UnsolvableVersionConflictException [英] Issues with maven dependencies: UnsolvableVersionConflictException

问题描述

我是grpc和java的新手.

Im new in grpc and java.

我的依赖项有很大的问题:

I have a big problem with my dependencies:

由以下原因引起:org.eclipse.aether.collection.UnsolvableVersionConflictException:无法解决[io.grpc:grpc-all:jar:1.27.1-> io.grpc:grpc-core:jar:[1.27]之间的版本冲突.1,1.27.1]，io.grpc:grpc-all:jar:1.27.1-> io.grpc:grpc-netty:jar:1.27.1-> io.grpc:grpc-core:jar:[1.27.1,1.27.1]，io.grpc:grpc-all:jar:1.27.1-> io.grpc:grpc-okhttp:jar:1.27.1-> io.grpc:grpc-core:jar:[1.27.1,1.27.1]，io.grpc:grpc-all:jar:1.27.1-> io.grpc:grpc-testing:jar:1.27.1-> io.grpc:grpc-core:jar:[1.27.1,1.27.1]，net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE-> net.devh:grpc-common-spring-boot:jar:2.6.2.RELEASE-> io.grpc:grpc-core:jar:1.25.0，net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE-> io.grpc:grpc-netty-shaded:jar:1.25.0-> io.grpc:grpc-core:jar:[1.25.0,1.25.0]，net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE-> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE-> io.grpc:grpc-services:jar:1.25.0-> io.grpc:grpc-core:jar:[1.25.0,1.25.0]]

Caused by: org.eclipse.aether.collection.UnsolvableVersionConflictException: Could not resolve version conflict among [io.grpc:grpc-all:jar:1.27.1 -> io.grpc:grpc-core:jar:[1.27.1,1.27.1], io.grpc:grpc-all:jar:1.27.1 -> io.grpc:grpc-netty:jar:1.27.1 -> io.grpc:grpc-core:jar:[1.27.1,1.27.1], io.grpc:grpc-all:jar:1.27.1 -> io.grpc:grpc-okhttp:jar:1.27.1 -> io.grpc:grpc-core:jar:[1.27.1,1.27.1], io.grpc:grpc-all:jar:1.27.1 -> io.grpc:grpc-testing:jar:1.27.1 -> io.grpc:grpc-core:jar:[1.27.1,1.27.1], net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE -> net.devh:grpc-common-spring-boot:jar:2.6.2.RELEASE -> io.grpc:grpc-core:jar:1.25.0, net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE -> io.grpc:grpc-netty-shaded:jar:1.25.0 -> io.grpc:grpc-core:jar:[1.25.0,1.25.0], net.devh:grpc-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-starter:jar:2.6.2.RELEASE -> net.devh:grpc-server-spring-boot-autoconfigure:jar:2.6.2.RELEASE -> io.grpc:grpc-services:jar:1.25.0 -> io.grpc:grpc-core:jar:[1.25.0,1.25.0]]

感谢所有建议.

推荐答案

添加对 io.grpc:grpc-netty-shaded:jar:1.27.1 和 io.grpc的依赖:grpc-services:jar:1.27.1 .这些工件目前未包含在grpc-all中.

Add a dependency on io.grpc:grpc-netty-shaded:jar:1.27.1 and io.grpc:grpc-services:jar:1.27.1. These artifacts aren't presently included in grpc-all.

    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-netty-shaded</artifactId>
        <version>1.27.1</version>
    </dependency>
    <dependency>
        <groupId>io.grpc</groupId>
        <artifactId>grpc-services</artifactId>
        <version>1.27.1</version>
    </dependency>

请注意，gRPC团队希望您避免使用grpc-all，而是参考您需要的特定依赖项；grpc-all引入了比许多用户所需更多的依赖项.

As a note, gRPC team would prefer you to avoid grpc-all and instead reference the specific dependencies you need; grpc-all pulls in far more dependencies than many users need.
