T G commented on MCOBERTURA-65:
-------------------------------
To anyone who would like to aggregate Cobertura's reports in a multi-module
Maven project which has a large number of submodules and/or very long pathnames
for each, then use James's patch given above but add a few lines of code into
CoberturaReportMojo.java. If it is failing because of these long pathnames, the
only thing you will notice is that your reports will say all complexities are 0
when they are not in fact 0.
What's happening is that it uses cmd.exe to run its commands, and then tries to
include way too many, huge source files, which goes over the cmd.exe 8191
character limit, failing the report aggregation with a general exception.
Here's what you add to CoberturaReportMojo.java to fix it:
In private void executeReport(File curDataFile, File curOutputDirectory, List
curCompileSourceRoots), add:
CommandLineArguments cmdLineArgs;
cmdLineArgs = new CommandLineArguments();
cmdLineArgs.setUseCommandsFile(true);
task.setCmdLineArgs(cmdLineArgs);
after you set the task defaults and specifics, but before you check the
formatting. This is enough to change to using the command file to list all of
the sources which need to be included instead of listing each explicitly on the
command line.
You also need to add an import statement at the top:
import org.codehaus.mojo.cobertura.tasks.CommandLineArguments;
Rebuild and install the plugin, and this should fix these problems. Hope it
helps!
