缺少工件 org.springframework:spring-core:jar:4.3.0.RELEASE

Question

我尝试使用 maven-springboot 创建一个 webbservice。以下是我在 pom 文件中使用的依赖项。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <artifactId>SpringService</artifactId>

  <packaging>war</packaging>

  <name>SpringService Maven Webapp</name>
  <url>http://www.example.com</url>

  <properties>

        <maven.compiler.target>1.8</maven.compiler.target>
  </properties>

        </dependency>
          <dependency>

            <artifactId>jackson-databind</artifactId>
            <version>${jackson.library}</version>
        </dependency>
  </dependencies>

但是，我收到一个错误 Missing artifact org.springframework:spring-core:jar:4.3.0.RELEASE for spring-web, spring -core 和 spring-webmvc。请提出解决方案。

Answer 1

删除文件夹 /Users/username/.m2/repository/org/springframework 然后运行 ​​maven install 对我有用。
