hi, please check you run configuration: before launch section. there should be 'Build' item in the list. if it is not -- add it manually.

[fechy]

Hi, I get the same thing with the new IntelliJ 2017.3. Same error.

@dkimitsa the 'Build' item that you mention is in the list, and judging by the screenshot that @luveti added he has it too.

Both Run and Debug fail.

[Longri]

I'm having the same error, after the update to 2017.3

latest PlugIn-snapshot (10-Dec-2017 00:11)

[dkimitsa]

hi, updated to 2017.3 and was not able to run debug build of plugin as every open dialog just hang. Rolled back to 2017.2 for now. Will be back on it once there is something from Intellij (https://youtrack.jetbrains.com/issue/IDEA-183584)

[fechy]

Update just FYI, tried new IntelliJ 2017.3.1 update and the latest RoboVM 2.3.4-SNAPSHOT Plug in and the same result.

[luveti]

Oops didn't mean to close that! I wanted to point out that "Build" is definitely in there (it's in the screenshot above).

[misha-bear]

Hey guys, any update how to resolve this issue?

[dkimitsa]

still unable to debug due idea bug. will try different way later today

[dkimitsa]

meanwhile checked on Windows Idea 2017.3.2 and it was able to deploy and start application. sorry can't test on Mac yet

[dkimitsa]

@misha-bear
there is PR which fixes few moments. At least 2017.3.2 is working for me

[misha-bear]

@dkimitsa
Thanks a lot mate! I'm using 2017.3.2 on Mac. I'm trying to checkout your PR and build plugin locally.

[misha-bear]

Tried with the latest changes, still having the same problem :(
Looks like in RoboVmRunProfileState (line 52) runConfig.getConfig(); returns null. That's why line 57 fails with NullPointerException. Do you have any clues why it might be the case?

[dkimitsa]

@misha-bear thanks for result, the case is RoboVmCompileTask is not being called in stack of compiler by Idea. So it is not being configured and compiled to Native. this means that project was not imported properly

can you tell what version of gradle is being used ? is it wrapper or local gradle disctribution.
also would help if you try the case and then look into idea log file (help-show log in finder) for any possible exceptions there.
thank you

[dkimitsa]

@misha-bear there are new findings, it seems to be related to https://youtrack.jetbrains.com/issue/IDEA-122904 bug, could you please try removing android project from settings.gradle and build.gradle, resync project and try agains ?

[misha-bear]

Removing Andorid didn't help. Same result.
BUT I switched from IntelliJ to Android Studio, imported the same project, and everything started to work. So I'm going to use AS instead.
RoboVM is awesome! Thanks a lot for your work, mate.

[varrav]

I have found that problem appears only when Android is included while generating the project via gdx-setup.jar

There is a workaroud:
open ios.iml and remove

<component name="FacetManager">
    <facet type="android-gradle" name="Android-Gradle">
      <configuration>
        <option name="GRADLE_PROJECT_PATH" value=":ios" />
      </configuration>
    </facet>
    <facet type="java-gradle" name="Java-Gradle">
      <configuration>
        <option name="BUILD_FOLDER_PATH" value="$MODULE_DIR$/build" />
        <option name="BUILDABLE" value="true" />
      </configuration>
    </facet>
  </component>

ios projects starts to run.

In Android Studio 3.0 all works fine in any case

[fgnm]

I have the same issue after upgrade Android Studio from 3.0.1 to 3.1, removing lines suggested by @varrav worked, but every time I restart the IDE the problem appears again.. Is there a persistent solution?

[dotw]

I have upgraded my AS to 3.1 and get a similar issue. Following the suggestion of @varrav . The error is gone but the app failed to startup with ClassNotFound error.

[dotw]

update: I rearrange project dependencies again, add many duplicated dependencies to the core for ios. the app can run now. This confused me. Why the previous version doesn't these adjustments?

[marcdubs]

@varrav's comment fixed it for me. Thanks. Still strange, however.

[dkimitsa]

@marcdubs it is know bug at Idea/Google side. Here are some details https://youtrack.jetbrains.com/issue/IDEA-122904
I have been trying to fight it time-to-time with google code fixing etc but at some point fixes stopped working. I ended up with idea plugin that removes these facets. It has issues in AS3 but works for me in Idea. Details in the post by the link.
