MAVEN 无法解决依赖关系 [重复]

【中文标题】MAVEN 无法解决依赖关系 [重复]【英文标题】：MAVEN couldn't resolve the dependencies [duplicate] 【发布时间】：2020-08-27 11:57:58 【问题描述】：我正在开发一个在 Tomcat 上运行的基于 Maven 的 Web 应用程序。
我正在尝试将 log4j2 依赖项添加到我的 maven 项目中。但是，当我尝试构建我的项目时，底部的错误会发生。我尝试在本地安装 log4j 依赖项，但是我也无法让它工作。我想重新安装 Maven，但不知何故我只能停用它。如果您需要更多信息，请告诉我，以便我提供。
我尝试构建项目时的输出：
cd C:\...\Blockchain; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.8.0_161" cmd /c "\"\"C:\\Program Files\\NetBeans 8.2\\java\\maven\\bin\\mvn.bat\" -Dmaven.ext.class.path=\"C:\\Program Files\\NetBeans 8.2\\java\\maven-nblib\\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 install\""

我现在能够构建项目。但是，当我尝试创建 Logger 对象时出现以下错误。在以下代码中，getLogger() 函数带有红色下划线，并带有以下错误文本：
代码：
package com.blockchain.api.services;
import com.blockchain.logic.DependencyManager;
import com.blockchain.logic.PendingTransactions;
import com.blockchain.models.Block;
import com.blockchain.models.Transaction;
import com.blockchain.utils.SHA3Helper;
import org.apache.logging.log4j.core.Logger;
import java.net.URI;
import java.net.URISyntaxException;

import java.util.List;
import javax.ws.rs.*;

import javax.ws.rs.core.UriInfo;
/**

@Path("transactions")
public class TransactionService
private static Logger logger = Logger.getLogger(Transaction.class);
错误
cannot find symbol
symbol: method getLogger(Class<Transaction>)
location: class Logger
【问题讨论】：
我也有类似的问题。我不得不为几个依赖项排除一些库。 Gradle config 但也许它会帮助 compile(group: 'commons-logging', name: 'commons-logging-api', version: '1.1') exclude(module: 'servlet-api') compile (group: ' org.apache.commons'，名称：'commons-dbcp2'，版本：'2.2.0'）排除（模块：'commons-logging'） 您尝试使用 http 从存储库下载，但您需要 https。您是否在 pom 或设置中添加了存储库标签？ 你必须使用https而不是http ....已更改blog.sonatype.com/central-repository-moving-to-https 添加完整的pom.xml 文件以检查存储库和依赖项标签。如果它有一个父 pom，请检查它的存储库。
@Christian 我还没有添加存储库标签。但是，当我尝试添加它们时，该项目仍会尝试从同一地址下载依赖项。
【参考方案1】：
您的日志记录工件似乎不正确。你可以试试这个：
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
您可以在此处确认此路径： https://repo.maven.apache.org/maven2/org/apache/logging/log4j/log4j-core/2.13.0/
另见： https://logging.apache.org/log4j/2.x/maven-artifacts.html
