Add sample ear project, runs without any issues.
Update example so it is an multi-module build. Still not able to
reproduce the issue.
Skip execution of report when target/classes does not exist.
Forgot to include fix: Skip execution of report when target/classes does not exist.
Add an empty resource file, so target/classes is created. Otherwise
the check for an existing outputDirectory will hide the error for
the invalid data-file.
Move IT for missing target/classes to it-multi-module so now new IT is
needed.
Add fixed bug to changes.
Merge pull request #169 from jacoco/issue-169
