启用 Maven 依赖管理会禁用 Eclipse 中的重构菜单项

Question

有没有人注意到，在 Eclipse 中为项目启用 Maven 依赖关系管理后，Java 编辑器上下文菜单上的重构项消失了？

有解决办法吗？补丁还是升级？还是拼凑？

更多信息： 需要进一步断言项目/包资源管理器上的上下文菜单不受影响。重构项仍然存在。

受影响的是 Java 编辑器 - 重构项从上下文菜单中消失。

Answer 1

这不是我所经历的。下面的屏幕截图显示了Maven项目上下文菜单中的重构条目：

替代文本 http://a.yfrog.com/img842/3705/screenshot008b.png

以及上下文菜单中的重构条目此 Maven 项目 的 Java 资源（在 Java 编辑器中右键单击时也会得到）：

alt text http://a.yfrog.com/img201/9843/screenshot009n.png

但请注意，我没有像你一样使用 Eclipse 和 m2eclipse，我在外部创建 Maven 项目Eclipse 和导入...>现有的 Maven 项目（我不喜欢向导）。但不确定这会有所不同。

Answer 2

我发现很难回答我自己的问题，但是......

答案是：要在 Eclipse 中获取 Maven 托管项目，请勿使用 m2eclipse 菜单创建或启用 Maven 依赖项托管项目。那些 m2eclipse 菜单项已损坏。

您必须在 shell/命令窗口中使用 mvn archetype:generate 命令来创建该项目。

mvn archetype:generate \
 -DgroupId=holy.moly \
 -DartifactId=holymoly \
 -Dpackage=holy.moly \
 -Dversion=1.0-VOILA

然后在 Eclipse 中使用 import:maven:existing maven project 菜单项将该项目导入到 Eclipse 中。

一些产品提供了有关如何从 shell/命令窗口生成 Maven 项目，然后导入到 Eclipse 的各自建议。例如，Vaadin 的：

mvn archetype:generate \
-DarchetypeGroupId=com.vaadin \
-DarchetypeArtifactId=vaadin-archetype-clean \
-DarchetypeVersion=LATEST \
-DgroupId=holy.moly  \
-DartifactId=holymoly \
-Dversion=1.0 \
-Dpackaging=war

但是，尝试启用 GWT 会导致错误。

使用 IAM：
我正在编辑说我从我的 helios 设置之一卸载了 m2eclipse 并安装了 IAM。 IAM 没有导致任何菜单项消失。我能够启用 GWT。

重构项仍在菜单上，但尝试在 Java 编辑器上重构或在项目资源管理器上重命名文件将失败：
