为什么我收到“不具有使用GWT的生命周期配置覆盖的”插件执行“错误？

问题描述

我正在使用STS，我从另一台机器导入了GWT项目。该项目使用m2eclipse。在构建项目时我收到这两个错误：

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:

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

怎么了？有没有进一步的配置需要做，所以 gwt maven插件的工作？

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

pom.xml 导致错误的代码：

推荐答案

如果您使用Eclipse Indigo（3.7）激活生命周期插件。
有关详细信息，请参阅。

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

只需将这个 pluginManagement 部分添加到您的 build 部分的 pom.xml 文件

Just add this pluginManagement section to your build section of your pom.xml file

<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
                <lifecycleMappingMetadata>
                    <pluginExecutions>
                        <pluginExecution>
                            <pluginExecutionFilter>
                                <groupId>org.codehaus.mojo</groupId>
