eclipse 为什么我会收到“使用 GWT 的生命周期配置未涵盖插件执行”错误？

Why am I receiving a "Plugin execution not covered by lifecycle configuration with GWT" error?

提问by Neets

I'm using STS and I imported a GWT project from another machine. The project uses m2eclipse. I'm getting these two errors when building the project:

我正在使用 STS 并且我从另一台机器导入了一个 GWT 项目。该项目使用m2eclipse。构建项目时出现这两个错误：

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:gwt-maven-plugin:2.2.0:i18n (execution: default, phase: generate-sources)    pom.xml /contactsgwt    line 175
Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-war-plugin:2.1.1:exploded (execution: default, phase: compile)  pom.xml /contactsgwt    line 198

What's wrong? Is there any further configuration that needs to be done so the gwt maven pluginworks?

怎么了？是否有任何进一步的配置需要完成才能gwt maven plugin正常工作？

The pom.xmlcode causing the error:

If you use Eclipse Indigo (3.7) you have to activate the lifecycle plugin. See herefor more details.

如果您使用 Eclipse Indigo (3.7)，您必须激活生命周期插件。请参阅此处了解更多详情。

Just add this pluginManagementsection to your buildsection of your pom.xmlfile

只需将此pluginManagement部分添加到您build的pom.xml文件部分
