Eclipse：导入Maven项目，缺少maven-gae-plugin [英] Eclipse: Import Maven project, missing maven-gae-plugin

问题描述

来自Visual Studio，我对Eclipse IDE来说非常新鲜。
发现它非常困难。我似乎收到错误消息类型丢失...一个 LOT 。

我遇到的最新问题，我在哪里只是不能解决是这样的：
我试图编译并运行这个示例项目： http://code.google.com/p/gwtgae2011/

1. 当我选择checkout maven projects from SCM我的SCM下拉是空的...
   
   所以我刚刚用Hg手动检查出来，没问题。


2. 尝试导入>现有的Maven项目似乎阅读pom.xml，但显示错误：
   
   没有找到处理maven-gae-plugin的市场条目：0.8.1：在Eclipse中解压缩。请参阅帮助获取更多信息。

由于我没有通过eclipse中的更新或市场找到它，我下载maven-gae-plugin（http://code.google.com/p/maven-gae-plugin/downloads/list）我想把它放入plugins或dropins文件夹应该够了，显然不是所以...

问题：如何解决这个错误？
（我尝试了3.6和3.7） p>

对于覆盖这些主题的一些好的eclipse教程的链接也非常受欢迎！

谢谢！

解决方案

我遇到这个错误，对我有用的是：

• 评论插件


• 导入到eclipse


• 取消注释插件


• 发现错误在插件XML中


• 修复插件XML中的错误

我不确定，但似乎这是一个不清楚的错误，关于pom的一些事情.xml无效。

Coming from Visual Studio, I'm pretty new to the Eclipse IDE. And finding it very difficult. I seem to get error messages of the type "missing ..." a LOT.

The latest issue I'm having, where I just can't get around is this: I"m trying to compile & run this sample project: http://code.google.com/p/gwtgae2011/

1. When I choose "checkout maven projects from SCM" my SCM drop down is empty...
   So I just checked it out with Hg manually. No problem.
2. Trying Import > Existing Maven Project. Seems to read the pom.xml alright, but shows an error:
   "No marketplace entries found to handle maven-gae-plugin:0.8.1:unpack in Eclipse. Please see Help for more information."

Since I can't find it through updates or market within eclipse I downloaded maven-gae-plugin (http://code.google.com/p/maven-gae-plugin/downloads/list). I figured just dropping it into the "plugins" or "dropins" folder should be enough. Apparently not so...

Question: How do I fix this error? (I tried both 3.6 & 3.7)

Links to some good eclipse tutorials covering these kinds of topics are very welcome too!

THANKS!

解决方案

I ran into this error, what worked for me was:

• Comment the plugin
• Import into eclipse
• Uncomment the plugin
• Discover an error in the plugin XML
• Fix error found in the plugin XML

I am not certain, but it seems like this is a unclear error that something about the pom.xml is invalid.
