Spring 2.2.1构建错误无法找到工件com.fasterxml.jackson：jackson-bom：pom：2.10.5

Question

我是 Spring boot 框架的新手，我spring-boot-starter-parent 在我的父 pom 中添加了 spring-boot-starter-parent

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.1.RELEASE</version>
        <relativePath/>     
</parent>

pom.xml

                </configuration>
            </plugin>

        </plugins>

    </build>
    <modules>

    </modules>
</project>

现在它显示了一个错误pom.xml。

Project build error: Non-resolvable import POM: Could not find artifact com.fasterxml.jackson:jackson-bom:pom:2.10.5 in central (https://repo.maven.apache.org/maven2)

我尝试了以下解决方案

• 更新我的maven项目
• 删除并重建.m2文件夹

请对上述查询提出建议。

Answer 1

maven 尝试解析的 jackson-bom 版本不在 maven 存储库中。当我检查最新版本时，版本是2.10.1。那么，您可以检查一下您的 pom.xml 中是否在任何地方显式设置了 jackson 版本吗？。如果您尝试删除它并让 Maven 解析来自 spring 的版本。
