Eclipse没有Java facet 1.8版 [英] Eclipse has no Java facet version 1.8

问题描述

我正在使用eclipse Kepler（企业版），Java 8和M2Eclipse并尝试制作Web应用程序。我已经去帮忙了 - > eclipse marketplace并安装了这两个补丁：

I am using eclipse Kepler (enterprise edition), Java 8, and M2Eclipse and trying to make a web application. I have already gone to help -> eclipse marketplace and installed these two patches:

• Java 8支持Eclipse Kepler SR2


• Java 8支持m2e for Eclipse Kepler SR2

这些补丁解决了我的很多问题，但是一个遗迹。我在eclipse中做了一个maven - > update，它除了工作区中唯一的web应用程序外，还更新了我的所有项目。它给我一个弹出消息，说项目方面java版本1.8不存在

Those patches cleared up a lot of my problems, but one remains. I did a maven -> update from within eclipse, it went and updated all my projects except the only web app in my workspace. It gives me a pop up message that says "Version 1.8 of project facet java does not exist"

我打开了我的项目属性并单击了Project Facets。果然，java facet最大版本是1.7。所以我想知道为什么我的其他项目没有同样的问题。我查看了其他项目中的属性，发现它们都没有使用Project Facets。我想这可能是因为我使用标准版的eclipse而不是企业版制作了所有以前的项目。

I opened my project properties and clicked Project Facets. Sure enough, the java facet maximum version is 1.7. So I am wondering why I don't have the same problem on my other projects. I viewed the properties on my other projects and discovered that none of them are using Project Facets at all. I think this might be because I made all of the previous projects using a standard edition of eclipse, not an enterprise edition.

所以我想我有几个问题。我如何让eclipse识别java facet 1.8？有没有办法让我的网络应用程序不使用Project Facets？我应该将Project Facets添加到我的其他项目中吗？

So I guess I have a couple questions. How can I get eclipse to recognize the java facet 1.8? Is there a way I can have my web app not use Project Facets? Should I add Project Facets to my other projects?

推荐答案

刚遇到此问题。我的问题是tomcat服务器在JRE的错误位置查找。要解决此问题：

Just ran into this issue. My problem was with the tomcat server looking in the wrong place for the JRE. To fix that:

• 在服务器选项卡中双击服务器


• 打开运行时环境


• 更改JRE选择器。

希望这可以节省时间
