“未找到前缀的插件”在Eclipse中出错 [英] "Plugin not found for prefix" error in Eclipse

问题描述

在Eclipse中，我导入了一个使用maven jetty插件的基于maven的项目。如果我从命令行运行 mvn jetty：run ，一切都可以正常运行。如果我在Eclipse中添加运行配置并尝试运行它，我会收到错误消息：

In Eclipse I imported a maven-based project which uses maven jetty plugin. If I run mvn jetty:run from command line, everything works fine. If I add a run configuration in Eclipse and try to run it, I get the error message:

[ERROR] No plugin found for prefix 'jetty' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/home/eugene/.m2/repository), central (http://repo1.maven.org/maven2)] -> [Help 1]

在Eclipe运行配置中，我使用：

In the Eclipe run configuration, I use:

• 基本目录： $ {project_loc}


• 目标： ：运行


• Maven运行时：外部

[ Help1 ]页面。我在maven配置文件中没有pluginGroup设置，但是我在pom.xml中提到了jetty插件，所以我猜一切都应该是好的（特别是因为一切都在命令行中运行）。在执行jetty运行配置之前，我试图在Eclipse中运行Maven clean，但没有帮助。项目编译并通过所有测试，只有jetty：运行在Eclipse中不起作用。

I read the [Help1] page. I don't have pluginGroup settings in maven configuration files, but I have the jetty plugin mentioned in pom.xml, so I guess everything should be fine (especially because everything works in command-line). I tried to "Run as > Maven clean" in Eclipse before executing the jetty run configuration, but it didn't help. Project compiles and passes all tests, only jetty:run does not work in Eclipse.

请帮助，我是Eclipse& Maven新手感谢提前。

Please help, I'm an Eclipse & Maven newbie. Thanks in advance.

推荐答案

它也不适用于我的命令行。

It does not work for me from command-line either.

可以在 settings.xml 中添加以下内容后，检查它是否有效：记录了？

Can you check if it works after adding the following in settings.xml as documented?

<pluginGroups>
    <pluginGroup>org.mortbay.jetty</pluginGroup>
</pluginGroups>

另请注意，插件有两个不同版本 - 较旧的 maven jetty plugin 和较新的 jetty maven插件。

Also note that there are two different versions of the plugin - the older maven jetty plugin and the newer jetty maven plugin.
