i just tried to move from helios to maven with my gwt 2.4 application. so i began to follow the steps here: http://code.google.com/p/google-web-toolkit/wiki/WorkingWithMaven
我只是试图用我的 gwt 2.4 应用程序从 helios 移动到 maven。所以我开始按照这里的步骤操作：http: //code.google.com/p/google-web-toolkit/wiki/WorkingWithMaven
but on step 3 - installing the feature "m2e connector for build-helper-maven-plugin" i get an error from Eclipse:
但在第 3 步 - 安装功能“用于 build-helper-maven-plugin 的 m2e 连接器”时，我收到来自 Eclipse 的错误消息：
Cannot complete the install because one or more required items could not be found.
Software being installed: m2e connector for build-helper-maven-plugin 0.15.0.201109290002 (org.sonatype.m2e.buildhelper.feature.feature.group 0.15.0.201109290002)
Missing requirement: m2e connector for build-helper-maven-plugin 0.15.0.201109290002 (org.sonatype.m2e.buildhelper 0.15.0.201109290002) requires 'bundle org.eclipse.m2e.jdt [1.1.0,1.2.0)' but it could not be found
Cannot satisfy dependency:

Is there a workaround for that or did I do something wrong?

The problem is not the GWT Eclipse plugin but m2e, that currently is at 1.0.x version, and not 1.1.0 or higher as requested by the build-helper connector version 0.15. I suggest to install the build-helper connector later, and try to install the 0.14 version (that works on my machine). Use this repository: https://repository.sonatype.org/content/repositories/forge-sites/m2e-extras/0.14.0/N/0.14.0.201109282148/
问题不在于 GWT Eclipse 插件，而是 m2e，它目前是 1.0.x 版本，而不是构建助手连接器版本 0.15 所要求的 1.1.0 或更高版本。我建议稍后安装 build-helper 连接器，并尝试安装 0.14 版本（适用于我的机器）。使用这个存储库：https: //repository.sonatype.org/content/repositories/forge-sites/m2e-extras/0.14.0/N/0.14.0.201109282148/
If you need an update site (e.g. because you are working with RAD and can only use an update site) there is a modified 0.15.0 update site definition: m2eclipse with 0.14.0 connector
如果您需要更新站点（例如，因为您正在使用 RAD 并且只能使用更新站点），则可以修改0.15.0更新站点定义：m2eclipse with 0.14.0 connector
To get it working do this:
要使其正常工作，请执行以下操作：
- Go to Help\Install new software\
- Click on Add
- Click on Local
- Add the unzipped folder as location
- 转到帮助\安装新软件\
- 点击添加
- 点击本地
- 将解压后的文件夹添加为位置
In the selection choose the m2e connector for build-helper-maven-plugin in version 0.14.0.
在选择中，为 0.14.0 版本的 build-helper-maven-plugin 选择 m2e 连接器。

Found a solution. You can install the correct version with no dependency failure via your eclipse console.
找到了解决办法。您可以通过 eclipse 控制台安装正确的版本而不会出现依赖项失败。
Open the relevant pom.xml, via the overview view, you should see the error message in red at the top saying "Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:buid..(Click fro details)
Right click and select discover m2e connector
Eclipse marketplace will be displayed, with thecorrect and required m2e connector.
select the buildhelper and click finish.
Follow instructions and install, restart eclipse
Voila, following next build, these maven errors should not occur anymore.
打开相关的pom.xml，通过概览视图，您应该会在顶部看到红色错误消息“生命周期配置未涵盖插件执行：org.codehaus.mojo:buid..（点击查看详细信息）
右键单击并选择发现 m2e 连接器
将显示 Eclipse 市场，以及正确且必需的 m2e 连接器。
选择 buildhelper 并单击完成。
按照说明安装，重启eclipse
瞧，在下一次构建之后，这些 Maven 错误不应再发生。

To install required version of m2e you could use following repository m2e 1.1 milestone. It's not well tested yet but I did not notice any error.
要安装所需的 m2e 版本，您可以使用以下存储库m2e 1.1 里程碑。它还没有经过很好的测试，但我没有注意到任何错误。

I had a similar issue where STS (3.9.1.Release) was saying I had an update for: "m2e connector for build-helper-maven-plugin" but then it would never complete and kept bugging me about it.
我有一个类似的问题，STS (3.9.1.Release) 说我有一个更新：“用于 build-helper-maven-plugin 的 m2e 连接器”，但它永远不会完成并一直困扰着我。
I added the following SonaType repository: https://repository.sonatype.org/content/repositories/forge-sites/m2e-marketplace-p2-repo/
我添加了以下 SonaType 存储库：https://repository.sonatype.org/content/repositories/forge-sites/m2e-marketplace-p2-repo/
Then STS was able to do the update it wanted to do.
然后 STS 能够进行它想做的更新。

Have a look at the last message in the thread you asked at m2e-users at eclipse.org. I have not tried it, so.
查看您在 eclipse.org 上的 m2e-users 上询问的线程中的最后一条消息。我没试过，所以。
