How to fix "Missing Gradle project configuration file" issue in Buildship?

Question

As an Eclipse user, I always liked the Gradle IDE. However, this plugin is now deprecated in favor of the new Buildship plugin.

After setting up a fresh Eclipse IDE with Buildship installed, I'm faced with the following error in all my Gradle projects:

missing gradle project configuration file: .settings/org.eclipse.buildship.core.prefs

There are several pages on google that deal with this issue, but all of them seem pretty outdated. There is also an entry in the bugtracker of the plugin which is set to "CLOSED FIXED". Well, apparently, it's not fixed.

Am I doing something wrong? Any ideas how to tackle this issue?

Answer 1

I've figured it out myself. The issue with the "missing gradle project configuration file" arises from the way the gradle project(s) are imported into Eclipse.

When importing a gradle project via the regular File -> Import -> General -> Existing Project into Workspace command, then it will not work and produce the aforementioned error.

However, if you import the very same project via File -> Import -> Gradle -> Existing Gradle Project, then you get a different import wizard, and with this wizard, it works like a charm.

I still think it's a bug because the choice of the import wizard should not matter. Still, choosing the proper wizard is a viable workaround.

Another option is to:

1. Move to your projects path (where gradle or gradlew is found)
2. Unix: sh gradlew cleaneclipse Win: gradlew cleaneclipse

Requires the apply plugin: 'eclipse' in your build.gradle

3. Refresh your Project in eclipse.
4. After that for Unix: sh gradlew eclipse Win: gradlew eclipse

Now the gradle nature will be missing in your eclipse-project. Open the context menu of your project -> configure -> add gradle nature

Now everything should be fine again.
