Eclipse Optimize Imports to Include Static Imports

Is there anyway to get Eclipse to automatically look for static imports? For example, now that I've finally upgraded to Junit 4, I'd like to be able to write:

assertEquals(expectedValue, actualValue);

hit Ctrl + Shift + O and have Eclipse add:

import static org.junit.Assert.assertEquals;

Maybe I'm asking too much.

I'm using Eclipse Europa, which also has the Favorite preference section:

Window > Preferences > Java > Editor > Content Assist > Favorites

In mine, I have the following entries (when adding, use "New Type" and omit the .*):

org.hamcrest.Matchers.*
org.hamcrest.CoreMatchers.*
org.junit.*
org.junit.Assert.*
org.junit.Assume.*
org.junit.matchers.JUnitMatchers.*

All but the third of those are static imports. By having those as favorites, if I type "assertT" and hit Ctrl+Space, Eclipse offers up assertThat as a suggestion, and if I pick it, it will add the proper static import to the file.


Ah - the trick is to simply add org.junit.Assert via New Type..., the .* is then implicit.
Is it correct that auto-import Ctrl+Shift+o won't add the necessary import, and in fact you must hover the cursor and choose Add static import.. option? It's a shame the usual auto-import selection list dialog doesn't display.
@J.Stoever - If you're using JUnit 4 you'll want to use the Hamcrest form: assertThat(value, is(expected));
I tried this with Eclipse Kepler, but to no avail. I restarted Eclipse as well. No autocompletion, no static import choice when hovvering or pressing CTRL + 1. Anyone experienced this?
Intellij Idea supports this out of the box. Shame eclipse doesn't.

If you highlight the method Assert.assertEquals(val1, val2) and hit Ctrl + Shift + M (Add Import), it will add it as a static import, at least in Eclipse 3.4.


In Eclipse Juno I've only managed to make it work if I highlight only the method and afterwards use the CTRL + SHIFT + M.
This should be the winner!
Works also for static fields A.X -> X (hightly A.X and Ctrl + Shift + M). Thanks. Exactly what i wanted.
Great! Was missing this feature so much
Works for me on Luna. Make sure your cursor is on the right side of the period. Wish I had learned about this years ago!

Eclipse 3.4 has a Favourites section under Window->Preferences->Java->Editor->Content Assist

If you use org.junit.Assert a lot, you might find some value to adding it there.

Not exactly what I wanted, but I found a workaround. In Eclipse 3.4 (Ganymede), go to

Window->Preferences->Java->Editor->Content Assist

and check the checkbox for Use static imports (only 1.5 or higher).

This will not bring in the import on an Optimize Imports, but if you do a Quick Fix (CTRL + 1) on the line it will give you the option to add the static import which is good enough.

From Content assist for static imports

To get content assist proposals for static members configure your list of favorite static members on the Opens the Favorites preference page Java > Editor > Content Assist > Favorites preference page. For example, if you have added java.util.Arrays.* or org.junit.Assert.* to this list, then all static methods of this type matching the completion prefix will be added to the proposals list.

Open Window » Preferences » Java » Editor » Content Assist » Favorites

For SpringFramework Tests, I would recommend to add the below as well

org.springframework.test.web.servlet.request.MockMvcRequestBuilders
org.springframework.test.web.servlet.request.MockMvcResponseBuilders
org.springframework.test.web.servlet.result.MockMvcResultHandlers
org.springframework.test.web.servlet.result.MockMvcResultMatchers
org.springframework.test.web.servlet.setup.MockMvcBuilders
org.mockito.Mockito

When you add above as new Type it automatically add .* to the package.

Shortcut for static import: CTRL + SHIFT + M

Select the constant, type

Ctrl + 1  (quick fix)

Select "Convert to static import." from the drop down.

"Quick fix" has options even though it is not an error.

In Eclipse 4.9, you can static import existing invocations using a quick fix.

A new quick fix has been implemented that allows the user to convert static field accesses and static methods to use a static import. It's also possible to replace all occurrences at the same time.
