Maven依赖项jar版本不同于pom.xml规范

Question

我不断得到原因:java.nio.file.nosuchfileException:C:\Program Files\Apache Software Foundation\Tomcat 9.0\WTPWebApps\WebApp\WEB-INF\lib\Jackson-DataBind-2.9.6.jar Exception。我的pom.xml文件中有2.9.6版本的依赖项，但Maven dependencies文件夹中有jackson-dataBind-2.11.2.jar。

有没有人知道这是什么原因，或者如何解决这个问题？为什么Jackson-DataBind-2.11.2.jar首先在那里？

这是我的pom.xml文件：

Answer 1

如果您正在使用eclipse，您可以右键单击您的项目，然后单击Maven>Update project...，然后选择Force Update of Snapshots/Releases复选框，然后单击OK。

如果您使用的是Intellij，在项目上右键单击Maven>Reimport

最后，您可以在项目根目录中MVN clean install或者如果您的项目中有maven包装器，则可以尝试通过终端在windows上MVNW clean install，或者在Linux上./MVNW clean install。
