Michael Zav'yalov created MCOMPILER-278:
-------------------------------------------
Summary: Incremental build does not track inter-module
dependencies.
Key: MCOMPILER-278
URL: https://issues.apache.org/jira/browse/MCOMPILER-278
Project: Maven Compiler Plugin
Issue Type: Bug
Affects Versions: 3.1
Reporter: Michael Zav'yalov
When useIncrementalCompilation=true the plugin actually assumes that this
incremental compilation is supported by compiler itself (I state it because of
all source files are always sent to compiler).
But plugin provides an additional optimization - it can detect that there are
no changes at all, so calling compiler can be skipped. It is especially
critical for javac that does not support incremental build since 1.3.
Unfortunately, plugin ignores claspath dependencies that are not directory,
i.e. - jars, so when dependent jar is modified (in incompatible way) - our
project is not re-compiled.
