java - 项目将无法识别任何 Maven 依赖项

Question

当我 maven install 我的项目时，出现以下错误:

Failed to execute goal on project xxx Could not resolve dependencies for project yyy:xxx:1.0:

这些依赖项都包含在我的pom.xml中。知道如何解决这个问题吗？我尝试添加settings.xml，但没有成功。 Settings.xml:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>C:\Users\abc\.m2\repository</localRepository>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies/>
  <profiles/>
  <activeProfiles/>

请帮忙，我被困住了。

您需要配置您的settings.xml 以指向托管您正在查找的 Artifact 的一个或多个存储库。它们将被下载到您的本地存储库中。例如:

<profiles>
    <profile>
        <id>central</id>
        <activation>
           <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>central</id>
                <url>http://repo1.maven.org/maven2</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>central</id>
                <url>http://repo1.maven.org/maven2</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </pluginRepository>
        </pluginRepositories>
    </profile>
</profiles>
