android - Gradle: FAILURE: Could not determine which tasks to execute

Question

Upgraded to Android Studio 0.2.0 and got the following error. The error got resolved after applying suggested solution but now the following error appeared.

Gradle: 
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'assemble' not found in root project 'MerlinCheckProject'.
* Try:
Run gradle tasks to get a list of available tasks.

I have no clue what the error is how to solve it. Appreciate help.

Answer 1

Remove <component name="FacetManager"> ... </component> from your iml file.

From http://tools.android.com/knownissues:

If you get the following error message:

Gradle: FAILURE: Could not determine which tasks to execute.

• What went wrong: Task 'assemble' not found in root project 'MyProject'.

• Try: Run gradle tasks to get a list of available tasks.

The real problem is that previous version of Android Studio misconfigured the IDEA file (e.g. MyProject.iml) -- it added an extra <component name="FacetManager"> XML element that shouldn't be present. In the case above, the solution is to edit MyProject.iml and to remove the <component name="FacetManager"> part as shown here:

<?xml version="1.0" encoding="UTF-8"?>
<module external.system.id="GRADLE" type="JAVA_MODULE" version="4">
  <component name="FacetManager">
    ...remove this element and everything inside such as <facet> elements...
  </component>
  <component name="NewModuleRootManager" inherit-compiler-output="true">
    ...keep this part...
  </component>
</module>

Alternatively you could remove the project's .idea folder and iml files and re-import your sources into a new Android Studio project.

In the next release we'll fix this -- there will be a "fix this" button to do that fix automatically for you.
