Building android projects - testing and code coverage issues

Hi all

I'm working on a project  consisting of both .NET code and android java projects. We're trying to get both types of projects working in one TeamCity environment.

The .NET projects are being tested through some NUnit projects, and we use DotCover to produce coverage reports and all seems swell. Now, the android/java projects are being built using ant runners, and we've got som build-scripts both for the production and for the test projects, and the problem is, it seems, the creation of the java coverage reports.

We've created a build step with the following ant targets:

     clean emma debug install test

The build step is set to have "Emma coverage runner" enabled (with the option "Include source files in the coverage data" checked).

An error occures when running the build step, stating the following in the log snippet (full log file is attached). Also the android/java unit tests doesn't appear in the overall statistics of the build:

Does anyone have an idea to what the problem might be?

By the way, when I run the targets directly from a command line, the reports are built without any problems.

First of all if you have your own ant tasks using emma, you probably do not need to enable TeamCity Emma integration. Also note that Emma coverage is a bit deprecated, as Emma project itself is not longer supported. You could have better luck with IntelliJ IDEA coverage engine bundled with TeamCity.
