Ben Hardy created MDEP-471:
------------------------------
Summary: Java 8 Method references are not detected
Key: MDEP-471
URL: https://jira.codehaus.org/browse/MDEP-471
Project: Maven Dependency Plugin
Issue Type: Bug
Components: analyze
Affects Versions: 2.9
Environment: Mac OSX
13.3.0 Darwin Kernel Version 13.3.0: Tue Jun 3 21:27:35 PDT 2014;
root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64
Reporter: Ben Hardy
It is possible to get the depedency plugin to fail to recognize methods
references.
For example, the following function declaration is the only place in its class
where the Guava "Lists" class is referenced (apart from imports):
public static <V> SequenceMap<String, Character, V> forStringKeys() {
return new SequenceMap<>(Lists::charactersOf);
}
We choose to fail when declared dependencies are thought to be unused, and this
usage is simply not detected, resulting in the following output and exception:
[WARNING] Unused declared dependencies found:
[WARNING] com.google.guava:guava:jar:18.0:compile
[INFO] ------------------------------------------------------------------------

Will try to get a test and patch attached to this once I figure out where your
test case class file resources are coming from.
