在执行Maven项目时：
mvn -X org.apache.maven.plugins:maven-dependency-plugin:3.1.2:go-offline --settings settings.xml
我收到以下错误：
...

在我的pom.xml中，我没有这种依赖性。我项目中的任何地方都没有提到jcifs:jcifs:jar。我还尝试了mvn dependency:tree -Dverbose和mvn dependency:tree -X，它们在输出中都没有jcifs:jcifs:jar:1.3.12。关于如何跟踪正在发生的事情的任何想法？

看起来像mvn回购中的jcifs:jcifs:1.3.12。
您可以尝试替换还是添加mvn依赖项
<dependency>
<groupId>jcifs</groupId>
<artifactId>jcifs</artifactId>
<version>1.3.17</version>
</dependency>
答案 1 :(得分：0)
看起来您的项目无法下载依赖项。尝试进行强制更新。
mvn -U clean install
答案 2 :(得分：0)
那么您需要确定它所指的是什么pom。您的项目不得正确配置或损坏。
尝试使缓存无效并重新启动
然后mvn clean install
发布到File => Maven => Synchronise
或
使用命令mvn -U idea:idea。这将刷新完整的缓存。
答案 3 :(得分：0)
我发现，如果我将以下内容升级到最新版本，那么我的问题就可以解决：
from:
<dependency>
<groupId>net.sourceforge.jtds</groupId>
<artifactId>jtds</artifactId>
<version>1.2.7</version>
</dependency>
to
<dependency>
<groupId>net.sourceforge.jtds</groupId>
<artifactId>jtds</artifactId>
<version>1.3.1</version>
</dependency>
