Upgrade to Maven Jacoco plugin 0.7.7

New Features

    New Maven goal report-aggregate to create reports for multi-module projects (GitHub #388).
    New parameters title and footer for Maven reporting goals allow customization of generated reports.
    Renamed "dot" resources in generated HTML reports to become more web hosting friendly (GitHub #401).
    Experimental support for Java 9 class files (GitHub #406).

Fixed Bugs

    Don't suppress EOF errors in case of truncated execution data files (GitHub #397).

Non-functional Changes

    JaCoCo now depends on ASM 5.1.
    Empty probe arrays are not written to execution data files any more. This reduces exec file size significantly for per-test data dumps. (GitHub #387).
    More information about context is provided when unable to read input during analysis. (GitHub #400).
    Require at least Maven 3.0 for build of JaCoCo.
