I am working on a project consisting of .NET and Android projects. We are trying to get both types of projects working in the same TeamCity environment.
.NET projects are being tested through some NUnit projects, and we use DotCover to generate coverage reports, and everything seems to be swellable. Now, android / java projects are built using ant runners, and we have some build scripts for both production and test projects, and the problem is reporting java coverage.
We created a build step with the following ant goals:
clean emma debug install test
In the construction step, it was found that “Emma coverage coverage is turned on” is enabled (with checking the checkbox “Include source files in coverage data”).
When starting the build step, an error occurs that indicates the following in the log fragment (the full log file is attached). Another important issue is that the unit tests of android / java do not appear in the general build statistics.
Here is the footnote of the magazine:

Does anyone have an idea what might be the problem?
By the way, when I run targets directly from the command line, reports are generated without any problems.
