Enabling maven dependency management disables refactor menu item in Eclipse

Question

Does anyone notice that after enabling Maven dependency management in Eclipse for a project, the refactor item on the context menu of Java editor disappears for that project?

Is there a solution to that? A patch or upgrade? Or a kludge?

Further Info: Need to further assert that the context menu on project/package explorer is unaffected. The refactor item is still there.

It is the Java Editor that is affected - where the refactor item disappeared from the context menu.

Answer 1

This is not what I'm experiencing. Below a screenshot showing the Refactoring entry in the contextual menu of a Maven Project:

And the Refactoring entry in the contextual menu of a Java Resource of this Maven Project (that I also get when right clicking in the Java editor):

But note that I'm not using Eclipse and m2eclipse like you are, I create Maven projects outside Eclipse and Import... > Existing Maven Projects (I'm not fan of wizards). Not sure this makes a difference though.

Answer 2

I find it hard to swallow answering my own question, but ...

The answer is: To obtain a maven managed project in Eclipse, do not use m2eclipse menu to create or enable as Maven dependency managed project. Those m2eclipse menu items are are broken.

You have to use mvn archetype:generate commands at the shell/command window to create that project.

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

And then in Eclipse use the import:maven:existing maven project menu item to import that project into Eclipse.

Some products give their respective advisory on how to generate a maven project from shell/command window, and then to be imported into Eclipse. For example, Vaadin's:

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

However, attempting to enable GWT would cause error.

Using IAM: I am editing to say that I uninstalled m2eclipse from one of my helios setup and installed IAM. IAM did not cause any menu items to disappear. I was able to enable GWT.

The refactor item was still on the menu but attempting to refactor on Java Editor or rename a file on Project explorer would fail:
