我在Maven Java项目中提到了标题错误。下面是一个好项目和我的问题项目的比较。
configurator, configurator,...
?即使没有错误标记,它看起来也很奇怪。我已阅读帖子:How to solve "Plugin execution not covered by lifecycle configuration" for Spring Data Maven Builds。
但它没有提供干净的镜头。它充满了解释,但没有规范的解决方案。
顺便说一下,我对Maven XML mess 感到非常沮丧,我必须找到一些替代方案。configurator
s。好的,我注意到在日食的Installation Details
中,没有m2e
个项目。奇怪的是如何在不安装的情况下导入maven项目。无论如何,我从http://www.eclipse.org/m2e/安装最新的1.6.2。而上述问题已经消失。
但这只是一个解决方案。我仍然不知道为什么会有这么多configurator
......
pom.xml

M2Eclipse需要明确说明如何处理绑定到项目构建生命周期某些阶段的所有Maven插件。这些指令被称为“生命周期映射”,因为它们定义了m2e
如何将项目pom.xml
文件中的信息映射到Eclipse配置。可以指示M2Eclipse执行插件执行的一个操作是委托给项目配置器。
配置程序映射告诉M2Eclipse使用projectConfigurators扩展点将用于匹配插件执行的工作空间项目配置映射委托给使用m2e注册的AbstractProjectConfigurator的实现。
这些扩展点位于每个Eclipse插件中。如果你看一下${ECLIPSE_HOME}\plugins
,你会发现一些名字以org.eclipse.m2e
开头的罐子。这些是M2Eclipse插件。
让我们以maven-war-plugin
的一些配置程序为例。要查看声明配置程序的位置,可以解压缩org.eclipse.m2e.wtp_1.2.1.20150819-2220.jar
(根据您的M2Eclipse版本名称可能不同)并打开文件lifecycle-mapping-metadata.xml
。对于war
包装,这就是我所拥有的:

你可以看到这声明了配置器。所有这些配置程序都是您在帖子中的对话框图片中看到的配置文件。
根据您的Eclipse安装,可以声明maven-war-plugin
的其他配置程序:
org.eclipse.m2e.wtp.jsf_1.2.1.20150819-2220.jar
org.eclipse.m2e.wtp.jaxrs_1.2.1.20150819-2220.jar
M2Eclipse extension development页面记录了如何创建新的m2e
扩展程序,并以antlr3-maven-plugin
为例。

你可以使用插件
基本上没有正确的配置这种类型的错误产生..
