I tried to delete repositories and install again. I got this error always. It looks like I need help. I think my mojo plugin is broken but i re installed it several times. Any suggestions?
我试图删除存储库并重新安装。我总是收到这个错误。看起来我需要帮助。我认为我的 mojo 插件坏了，但我重新安装了几次。有什么建议？

Does the class org.apache.maven.shared.filtering.MavenFilteringExceptionexist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar?
该类是否org.apache.maven.shared.filtering.MavenFilteringException存在于file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar？
The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.
错误消息表明它没有。也许 JAR 以某种方式损坏了。
I'm also wondering where the version 1.0-beta-2comes from; I have 1.0on my disk. Try version 2.3of the WAR plugin.
我也想知道版本1.0-beta-2是从哪里来的；我有1.0我的硬盘上。尝试版本2.3的 WAR 插件。

Faced the same issue and resolved by upgrading my Maven from 3.0.4 to 3.1.1. Please try with v3.1.1 or any higher version if available
遇到同样的问题并通过将我的 Maven 从 3.0.4 升级到 3.1.1 来解决。如果可用，请尝试使用 v3.1.1 或任何更高版本

this happened to me too after adding the version tag, that was missing, to the maven-war-plugin (not sure what version was using by default, i changed to the latest, 2.6 in my case). I had to wipe .m2/repository to have the build succeed again.
在将缺少的版本标记添加到 maven-war-plugin 后，这也发生在我身上（不确定默认情况下使用的是哪个版本，我更改为最新版本，在我的情况下为 2.6）。我必须擦除 .m2/repository 才能再次成功构建。
I tried first to clean the maven-filtering folder (in the repo) but then instead of a MavenFilterException i was getting an ArchiverException. So i concluded the local repository was corrupted (for a version upgrade?) and i deleted everything.
我首先尝试清理 maven-filtering 文件夹（在 repo 中），但随后我收到了 ArchiverException 而不是 MavenFilterException。所以我得出结论本地存储库已损坏（用于版本升级？）并且我删除了所有内容。
That fixed it for me. Just clean your local repo.
那为我修好了。只需清理您的本地仓库。

Try to delete the maven folder at ~/.m2/repository/org/apache/mavenand build your project again to force the maven libraries be downloaded. This worked for me the last time I faced this java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFilteringException.
尝试删除~/.m2/repository/org/apache/maven 中的 maven 文件夹并再次构建您的项目以强制下载 maven 库。上次我遇到这个 java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFilteringException 时，这对我有用。

You should add maven-resources-pluginin your pom.xmlfile. Deleting ~/.m2/repositorydoes not work always.
您应该在pom.xml文件中添加maven-resources-plugin。删除~/.m2/repository并不总是有效。
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.4</version>
</plugin>
</plugins>
Now build your project again. It should be successful!
现在再次构建您的项目。应该会成功！

My solution below is for cases when default maven repositories are not accessible (e.g. due to firewalls).
我下面的解决方案适用于无法访问默认 maven 存储库的情况（例如，由于防火墙）。
In case the default repository is not accessible appropriate local <pluginRepository>has to be specified in the settings.xml. If it's the same as your local artifact repository it still needs to be added to the <pluginRepositories>section for plugin jars to be found. Regular <repositories>section is not used to fetch plugin jars.
如果默认存储库不可访问<pluginRepository>，则必须在 settings.xml 中指定适当的本地。如果它与您的本地工件存储库相同，则仍需要将其添加<pluginRepositories>到要找到插件 jar的部分。常规<repositories>部分不用于获取插件 jar。
In my case, however, the issue was caused by the fact that there were multiple plugin repositories defined in that section.
但是，就我而言，问题是由于该部分定义了多个插件存储库这一事实引起的。
The first repository in the list did not contain the required maven-filtering jar.
列表中的第一个存储库不包含所需的 maven 过滤 jar。
I had to change the order of <pluginRepository>definitions to ensure the first one contains maven-filtering.
我不得不更改<pluginRepository>定义的顺序以确保第一个包含 maven 过滤。
Changing of repository definitions typically requires to clean ~/.m2/repository and start fresh.
更改存储库定义通常需要清理 ~/.m2/repository 并重新开始。

Make sure your Java version matches the project's Java version requirement. This could be an another cause for such kinds of issues.
确保您的 Java 版本符合项目的 Java 版本要求。这可能是此类问题的另一个原因。
