我有以下POM,只有一个依赖:
<?xml version="1.0" encoding="UTF-8"?>
<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>com.xxx</groupId>
<artifactId>mavenproject1</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-parent</artifactId>
<version>1.3</version>
</dependency>
</dependencies>
</project>
我正在尝试使用mvn dependency:resolve -X -U
来解决单个依赖项,但是我遇到了以下异常。任何想法如何解决?其他人得到同样的问题?我不明白为什么它不会从中央解决

正确。没有jar
类型的工件,如果您未指定任何工件,则默认为默认工件。这个可行:
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-parent</artifactId>
<version>1.3</version>
<type>pom</type>
</dependency>
