IJavaModelCoverage -> getProjects empty

[Mario Ackerl]

Hi,

while running JUnit Tests with coverage I got empty csv files (only header) when writing them down, but exec files were written with content. 

When I look into coverage view in eclipse the elemnts also stay empty. However if I re-import a written exec file it gets populated.

The reason seems to be that IJavaModelCoverage->getProjects() returns an empty IJavaProject array. What could be the reasons?

Thanks,

Mario

Hallo Mario,

can you please explain step by step what you are doing to get the CSV file?

Cheers,

Hi Marc,

I will try to get the major pieces:)

First of all background - we are talking about an enterprise application using an development environment based on eclipse. The build system is using https://www.eclipse.org/tea/. 

We also program within the IDE some pieces (like starting a unit test or recording coverage) - and the IDE is also used in headless mode as the eclipse build is not possible without. 

First step is to record coverage by using a CoverageLaunch

Then there is an ISessionListener implemented that stores the ICoverageSessions on "sessionAdded".

Finally those sessions are added to an ISessionManager and the sessions are written to disk

with coverageReportWriter containing

I hope that makes things clearer :)

Thanks,

Mario

Hi,

while writing down I found the answer ... our problem is at the beginning .. when selecting the plugins. .. So can be closed :)

Thanks,
