MAVEN无法解析依赖项[重复]

Question

我正在开发一个运行在Tomcat上的基于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。然而，当我试图构建我的项目时，底部的错误发生了。我尝试在本地安装log4j依赖项，但我也无法使其正常工作。我想重新安装Maven，但不知为什么我只能停用它。如果你需要更多的信息，请告诉我，我可以提供。

当我尝试构建项目时输出：

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\""

您的日志记录工件似乎不正确。你能试试这个吗：

<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/
