maven - 如何解决 pom.xml 中的依赖错误

Question

我是 Maven 的新手，在 pom.xml 文件中添加依赖项时出现此错误。下面是我的 pom.xml 文件:

<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">
  <modelVersion>4.0.0</modelVersion>
  <groupId>CrunchifyRESTJerseyExample</groupId>
  <artifactId>CrunchifyRESTJerseyExample</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <dependencies>
    <dependency>
        <groupId>asm.jar</groupId>
        <artifactId>asm.jar</artifactId>
        <version>3.3.1</version>
    </dependency>
    <dependency>
        <groupId>jersey-bundle.jar</groupId>
        <artifactId>jersey-bundle.jar</artifactId>
        <version>1.18.1</version>
    </dependency>
    <dependency>
        <groupId>json.jar</groupId>
        <artifactId>json.jar</artifactId>
        <version>20140107</version>
    </dependency>
    <dependency>
        <groupId>jersey-core.jar</groupId>
        <artifactId>jersey-core.jar</artifactId>
        <version>1.18.1</version>
    </dependency>
    <dependency>
        <groupId>jersey-bundle</groupId>
        <artifactId>jersey-bundle</artifactId>
        <version>1.18.1</version>
    </dependency>
  </dependencies>
</project>

对于每个依赖项，都会显示错误

Missing artifact json.jar:json.jar:jar:20140107
Missing artifact asm.jar:asm.jar:jar:3.3.1
Missing artifact jersey-bundle.jar:jersey-bundle.jar:jar:1.18.1
Missing artifact jersey-bundle:jersey-bundle:jar:1.18.1
Missing artifact jersey-core.jar:jersey-core.jar:jar:1.18.1

请帮我解决这个问题。

谢谢!!

不能直接写jar的名字。大多数时候 groupId 指的是“packages”，而 artifactId 指的是依赖项的名称。如需示例，请转至 http://mvnrepository.com/artifact/com.sun.jersey/jersey-core/1.18.3
