Gradle still not working with Eclipse 4.4.0 about eclipse-integration-gradle HOT 4 CLOSED

Did you try executing "./gradlew build” from the command line for your project by any chance? It might be the problem with Gradle itself rather than Gradle Eclipse tooling…
Perhaps the best way to tackle this would be for you to give us a sample project such that we could reproduce it. Any chance you can provide us with a sample project?

While many 4.4.1 related issues have been fixed over the last few days, it seems that there're still some fixes needed.

I'm working off of the latest nightly build from 10.4.2014 (which i assume will eventually turn into 3.6.2) of the integration plugin. The project uses the Gradle wrapper, using Gradle version 2.1.

When building the model for a Gradle project in the import dialog i receive the following error:

We tell our users (libGDX) to use the Gradle Integration for Eclipse. This is currently a huge blocker for us and thousands of end users on Eclipse 4.4 and we'd appreciate any help with this.

Terribly sorry, it's already been a long day. It indeed seems to be an issue with our build files. However, performing a build on the CLI or importing and building via Intellij IDEA works as intended. I'll see if i can track the issue down within the Gradle integration plugin.

Here's a test project: http://libgdx.badlogicgames.com/downloads/test.zip

However, it appears that the problem lies within the Android project's build.gradle file. Setting this up on your end would require you to install the Android SDK and modifying local.properties to point to the proper Android SDK directory. Probably to much work. We try to figure this out and report back.

from eclipse-integration-gradle.

We tracked it down to an issue in our build file, see line 85 here: https://github.com/libgdx/libgdx/blob/b88e96ba2c445d30d4202e593f819c2c300f4f96/extensions/gdx-setup/src/com/badlogic/gdx/setup/resources/android/build.gradle#L85

Instead we have to append this as an array/list now:

https://github.com/libgdx/libgdx/blob/master/extensions/gdx-setup/src/com/badlogic/gdx/setup/resources/android/build.gradle#L85

Now, the question is why CLI Gradle and Intellij IDEA had no problem with the old way of doing things. If this may indicate an issue in the Gradle Integration plugin and we could help in any way let me know.

Thanks and keep up the good work!

from eclipse-integration-gradle.

To me this look like it is most likely a bug in gradle tooling api implementation and/or the gradle eclipse plugin (i.e. gradle's plugin for eclipse not STS plugins for gradle). What you were doing seems like it should probably work (without wrapping an extra '[...]' around your code).
However the error comes from gradle code, not STS/eclipse code.

Useful to try: When you generate the eclipse classpath using commandline gradle... e.g: "./gradlew cleanEclipse eclipse" does it also give the same error?

If so then it would be wortwhile to follow up but raising a gradle bug report.
