Java 意外的可传递依赖项版本

使用spring boot设置一个干净的

Maven

项目，以便使用

JUnit

4和5进行测试，我最终得到以下依赖项：

通过

spring boot starter测试

在3.1.0版中定义

Mockito

。然而，项目junit55具有版本1.9.10的字节伙伴依赖性，而OpenPatricianModel具有版本1.10.1的字节伙伴依赖性。该依赖项在项目中没有明确定义

---

我怎么可能对OpenPatricianModel有不同的字节伙伴依赖关系，我怎么才能找到它的来源。

字节伙伴依赖关系被至少一个比

org.springframework.boot:spring boot starter test

多的依赖关系临时拉入。通过您的

OpenPatricianModel

的依赖关系树中的byte buddy范围，您可以看到这一点。请注意，范围是

compile

，而不是

test

找出哪个依赖项正在引入它的最佳方法是在spring boot starter测试的声明中添加对

byte buddy

依赖项的排除。比如：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>net.bytebuddy</groupId>
            <artifactId>byte-buddy</artifactId>
        </exclusion>
        <exclusion>
            <groupId>net.bytebuddy</groupId>
            <artifactId>byte-buddy-agent</artifactId>
        </exclusion>
    </exclusions>
</dependency>

org.springframework.boot
弹簧起动试验
测试
net.bytebuddy
字节伙伴
net.bytebuddy
字节好友代理

---

然后，通过再次运行

mvn-dependency:tree

，您应该能够看到哪个依赖项正在引入。请注意，可能不止一个，在这种情况下，您将不得不再次进行相同的练习。

真奇怪。您是否明确定义了任何存储库？或者您的父项目是否定义了可能导致mockito的不同pom文件的存储库？（这不太可能是因为这是一个发布版本）@ernest_k：没有明确定义存储库。junit55没有父pom，而OpenPatricianModel有一个处理依赖关系管理的pom。
