您可以删除.m2文件夹本身，并强制MyEclipse在启动时重新下载所有依赖项。进入Window > Preferences > MyEclipse > Maven4MyEclipse。

由于删除了'maven-compiler-plugin 2.0.2'而出现上述错误 来自maven存储库。 对我来说，当我将'maven-compiler-plugin'降级到2.0或2.0.1版本时，上述错误得到了解决。

这件事也发生在我身上，对此你可能有两种解决办法

If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C:\Users\Mohit.Singh.m2\repository folder and then you have to run mvn eclipse:eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --> GO to maven --> Click on update project a window will appear check the force snapshot download option and hit on OK

我在Eclipse 3.6和m2eclipse中有类似的问题。

无法计算构建计划:未能将org.apache.maven.plugins:maven-resources-plugin:jar:2.4.3从http://repo1.maven.org/maven2传输到本地存储库中，直到central的更新间隔已过或强制更新，才会重新尝试解决方案。原始错误:无法从中心转移工件org.apache.maven.plugins: Maven -resources-plugin:jar:2.4.3 (http://repo1.maven.org/maven2): ConnectException project1未知Maven问题

删除所有maven*。来自本地存储库的lastUpdated文件(正如Deepak Joy建议的那样)解决了这个问题。

在我的例子中，我在spring工具4中得到了这个错误消息

ArtifactTransferException: org.codehaus.plexus:plexus-interpolation:jar:1.26 failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.codehaus.plexus:plexus-interpolation:jar:1.26 from/to central (https://repo.maven.apache.org/maven2): repo.maven.apache.org java.lang.reflect.InvocationTargetException

这是解决方案

步骤01 -首先关闭弹簧工具应用程序

步骤02 -进入路径C:\Users\User并删除。m2文件夹

步骤03 -现在去包探索和选择你的项目

第04步-现在右键单击您的项目，进入Maven，单击更新项目

如何卸载Spring Tool 4
